Study Details (Non-Clinical Testing for Substantial Equivalence)
-
Sample size used for the test set and the data provenance:
- The document describes non-clinical testing which typically does not involve a "test set" of patient data in the same way an AI algorithm study would. Instead, it involves testing the hardware and software against engineering specifications and regulatory standards.
- No specific sample sizes for image data or patient cases are mentioned, as this is not a clinical performance study. The "test set" consists of the physical device components and software.
- Data provenance: N/A for this type of non-clinical testing. The "testing" is conducted on the manufactured device itself or its components.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable (N/A). The "ground truth" for non-clinical engineering and regulatory compliance testing is established by the specifications and standards themselves, not by expert interpretation of medical images. For example, the ground truth for "Electrical Safety" is whether the device meets the specified limits in IEC 60601-1, which is measured by test equipment, not human experts.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- N/A. Adjudication methods are relevant for studies involving human interpretation where consensus is needed to establish ground truth for medical conditions. This document details engineering compliance testing.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No MRMC study was done. This submission is for a diagnostic ultrasound system, not an AI-assisted diagnostic tool. There is no mention of AI assistance for human readers.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- No standalone algorithm performance was done in the context of diagnostic interpretation. This is a medical imaging device, not a standalone AI diagnostic algorithm.
-
The type of ground truth used:
- For the non-clinical testing, the "ground truth" is defined by established engineering standards (e.g., IEC 60601-1, IEC 60601-2-37, ISO 10993) and the device's internal performance specifications. For instance, the ground truth for "Acoustic Output" is the maximum derated ISPTA and Mechanical Index values allowed by the standard, and the device is tested to ensure it operates within these limits.
-
The sample size for the training set:
- N/A. This is a hardware and software system, not an AI/machine learning model that requires a "training set" of data in the common sense. The software validation refers to standard software development lifecycle testing, not AI model training.
-
How the ground truth for the training set was established:
- N/A, as there is no "training set" in the context of AI.
Summary of the Study:
The "study" described in the provided document is a comprehensive set of non-clinical, engineering, and regulatory compliance tests.

The device is intended for use by a qualified physician for ultrasound evaluation of: Ophthalmic; Fetal/obstetric, gynecological; Abdominal (renal, GYN/Pelvic; Intra-operative (abdominal, thoracic, and vascular), Intra-operative neurological; Pediatric; Small organ (thyroid, breast, testes, etc), Adult & Neonatal Cephalic; Trans-rectal, Trans-vaginal, Trans-cranial, Trans-esophageal (non-cardiac); Musculoskeletal (conventional & superficial); 3D/4D; Cardiac - Adult/Pediatric/Fetal; Echo, Intra-Cardiac; Pelvic: Peripheral vascular; harmonic tissue and contrast imaging and Tissue elasticity, Vet and others as stated in 1.3.
The ZONARE ZS3 is a general purpose diagnostic ultrasound system which consists of a the previous cleared portable scanner integrated into the ZONARE z.one Ultra Smartcart to enable the user to focus on performing patient scans with a more streamline unit. No longer convertible, the ZONARE ZS3 will still be considered a mobile system as it will be lightweight and easy to move from room to room. The new system, which uses the same software base as the currently approved z.one Ultra ultrasound system, will have . hardware changes which are minimal, but require some redesign in the cart base in order to put working components of the scanner inside the cart. Otherwise, the user interface and other features/functionalities of the system are substantially equivalent to the ZONARE Ultra Ultrasound System in both indications for use and system functionality. The new ZS3 will be based on the ZONARE's patented zone sonography, and with the scanner's internal components now inside the cart base, the ZS3, without compromising safety and effectiveness, should improve image quality through a higher signal to noise ratio, as well as support a wider range of future enhancements. Features, such as multi transducer ports will be standard in the system as will an embedded hard drive and DVD. The system with the ZONARE Ultra current suite of transducers. Signals received from the transducer module are digitized and preprocessed. The transducer module comes into contact with the patient and both transmit and receive ultrasound energy. There is no difference between the currently cleared ZONARE transducers (K101091) and the transducers as shown in this submission for the ZS3. The system provides holders for transducer models, and will be offered with battery chargers and other accessories. The modification for this submission includes no new indication for use but does have 1 transducer the C10-3 added as appendix E to the ZONARE z.one Ultra Ultrasound system which will be declared new to this system.
The provided document describes a 510(k) premarket notification for the ZONARE ZS3 Ultrasound System. This submission asserts substantial equivalence to previously cleared devices. It does not contain information about specific acceptance criteria, device performance, or a study designed to prove the device meets performance criteria in the way a clinical trial for a novel device would.
Instead, the document focuses on:
- Predicate Device Comparison: Demonstrating that the ZONARE ZS3 is substantially equivalent to currently marketed ZONARE z.one Ultra Ultrasound System (K082326, K101091) and other predicate devices in terms of features, functionality, indications for use, safety, effectiveness, software, materials, and design/construction.
- Non-clinical tests: Compliance with applicable medical device quality systems and safety standards (e.g., ISO 14971, IEC/UL 60601-1, IEC 62304, ISO 10993, AIUM Medical Ultrasound Safety).
- Indications for Use: Listing the various clinical applications and modes of operation for the system and its associated transducers. The document distinguishes between "new" (N) indications for the system (which usually refers to the C10-3 transducer being new to this specific system, but its indications are compared against existing ones) versus "previously cleared by FDA 510(k)" (P) for other transducers, implying that the performance for these previously cleared indications was established by prior submissions.
Based on the provided text, a conventional "acceptance criteria" table and a "study proving the device meets the acceptance criteria" as requested does not exist in the typical sense for a clinical performance study. The submission relies on demonstrating substantial equivalence to a predicate device, which usually means showing that the new device is as safe and effective as the predicate without necessarily conducting new clinical efficacy studies.
Specifically, the document states: "Clinical Tests: Not Required". This is a key piece of information.
Therefore, many of the requested fields cannot be directly answered from the provided text, as the regulatory pathway chosen (510(k)) and the nature of the submission (substantial equivalence to a predicate device with minimal hardware changes and the same software) did not necessitate the types of studies that would generate such data.
Here's how to address the request based on the available information:
1. A table of acceptance criteria and the reported device performance
As "Clinical Tests: Not Required" is stated, there are no specific clinical acceptance criteria or reported device performance metrics from a dedicated clinical study for this 510(k) submission. The acceptance criteria for substantial equivalence are that the device is as safe and effective as legally marketed predicate devices. The "performance" is implicitly demonstrated through compliance with non-clinical safety standards and the established performance of the predicate device with which it shares key components and software.
| Acceptance Criteria Category | Specific Criteria (Implied by 510(k) route) | Reported Device Performance |
|---|---|---|
| Clinical Performance | Not Applicable (Clinical Tests: Not Required). The device must be "as safe and effective" as the predicate devices (ZONARE z.one Ultra Ultrasound System K082326, K101091) for its stated Indications for Use. This implies its image quality, diagnostic accuracy, and functionality are comparable to the predicate. | Not Applicable (Clinical Tests: Not Required). The device is stated to have the "same software revision, driving both systems" (ZS3 and z.one Ultra), same indications for use and system functionality, and minimal hardware changes. It "should improve image quality through a higher signal to noise ratio" as a potential future enhancement, but this is not reported as a measured performance metric. |
| Non-Clinical Performance | Compliance with: - ISO 14971 (Risk Management) - IEC/UL 60601-1 (Electrical Safety) - IEC 60601-1-1 (Systems Safety) - IEC 60601-1-2 (EMC) - IEC 60601-1-4 (Programmable Medical Systems) - IEC 60601-2-37 (Ultrasonic Diagnostic Safety) - IEC 62304 (Software Life Cycle) - ISO 10993 (Biocompatibility) - AIUM Medical Ultrasound Safety - Verification and Validation - Cleaning and Disinfection effectiveness - Thermal, Electrical, and Mechanical safety, Acoustic output | "The device has been evaluated according to the applicable medical device quality systems, safety standards...", and "The device conforms to applicable medical device safety standards and compliance for safety and effectiveness which is verified through defined verification and validation, and market surveillance." |

- Adjudication Method: Not applicable. Clinical tests were not required.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Study: No, an MRMC comparative effectiveness study was not done. The device is a diagnostic ultrasound system, not an AI-assisted diagnostic tool in the sense of providing enhanced interpretation.
- Effect Size of Human Reader Improvement with AI: Not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone Performance Study: No, this is not an algorithm-only device. It's an ultrasound imaging system that requires human operation and interpretation.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Type of Ground Truth: Not applicable. Clinical tests were not required. The "ground truth" for demonstrating substantial equivalence rests on the established safety and effectiveness of the predicate ZONARE z.one Ultra Ultrasound System.
8. The sample size for the training set
- Sample Size for Training Set: Not applicable. This device is not an AI/machine learning device that typically involves a training set for model development in the context of a clinical performance study.

| Compliance with Applicable Medical Device Safety Standards | "The device conforms to applicable medical device safety standards..." (See list of ISO/IEC standards above) |
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "Clinical Tests: Not Required."
This indicates that no dedicated clinical test set (i.e., a set of patient data specifically collected for performance evaluation against a ground truth) was used in this 510(k) submission. The basis for safety and effectiveness is the substantial equivalence to previously cleared devices and compliance with non-clinical standards.
Therefore, information regarding data provenance (country of origin, retrospective/prospective) and sample size for a test set is not applicable to this submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Since no clinical tests or dedicated test sets were used, there were no experts required for establishing ground truth from such a set.
4. Adjudication Method for the Test Set
Not applicable, as no dedicated clinical test set was used.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance
Not applicable. This is a 510(k) submission for an ultrasound system, not an AI-powered diagnostic device. The application does not mention any AI components or MRMC studies.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is a medical imaging system, not an algorithm being submitted for standalone performance evaluation.
7. The Type of Ground Truth Used (Expert Consensus, Pathology, Outcomes Data, etc.)
The document does not describe the use of specific ground truth types (like pathology or outcomes data) in a clinical study context for this submission, as no clinical studies were deemed necessary. The ground truth for demonstrating safety and effectiveness relied on the established performance of the predicate devices and the compliance with engineering and safety standards.
8. The Sample Size for the Training Set
Not applicable. Given that "Clinical Tests" were "Not Required" and there's no mention of an algorithm or AI being developed, there would be no training set in the context of device performance evaluation. The device development process would have involved engineering testing and verification, but not "training data" in the sense of machine learning.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as no training set (for an algorithm/AI) was mentioned or used in this submission.

The z.one Ultra is a general purpose diagnostic ultrasound system. It consists of a portable scanner approximately 8 inches wide and 3 inches high that can be held by the user in one hand and includes buttons for controlling the system and a screen that display ultrasound mages and user interface. The portable scanner can be held by the user in one hand accommodates a removable transducer module. Signals received from the transducer module are digitized and preprocessed. The transducer module comes into contact with the patient and receive ultrasound energy.
The docking station (aka carts) provides holders for the portable scanner, and transducer modules, as well as battery chargers and other accessories. The modification for this submission include new features and functionality that will enhance user convenience and work flow as well as provide clinicians with new indications of use.
The provided document is a 510(k) premarket notification for the ZONARE z.one Ultra Ultrasound System. This type of submission is for demonstrating substantial equivalence to legally marketed predicate devices, not for proving the device meets acceptance criteria through clinical studies in the same way a new, high-risk device might.
The document explicitly states: "Clinical Tests: Non Required" and then elaborates: "ZONARE designs and develops their products according to 21 CFR 820, ISO 13485:2003 quality systems. The device conforms to applicable medical device safety standards and compliance for safety and effectiveness is verified through defined evaluation and market surveillance. Conforming to the required worldwide ultrasound standards, enables ZONARE to state that the ZONARE z.one Ultra Diagnostic Ultrasound System is substantially equivalent with respect to safety and effectiveness to devices current cleared for market."
Therefore, many of the requested categories related to clinical study design and performance metrics cannot be directly extracted from this document, as such studies were not required for this type of submission. The "acceptance criteria" here largely refer to the device's ability to perform its intended functions similarly to predicate devices and adherence to safety standards.
Here's a breakdown based on the available information:
1. Table of Acceptance Criteria and Reported Device Performance
Since formal clinical studies with specific performance metrics are not required and therefore not reported in this 510(k), I can only infer the "acceptance criteria" as meeting the general capabilities and safety standards demonstrated by predicate devices.
| Acceptance Criterion (Inferred from 510(k) context) | Reported Device Performance and Compliance |
|---|---|
| Intended Use Equivalence: The device must perform the same diagnostic ultrasound imaging or fluid flow analysis for the human body as predicate devices across various clinical applications and modes of operation. | The ZONARE z.one Ultra is reported as "comparable and substantially equivalent to the currently marketed ZONARE z.one and the Voluson i, Siemens Acuson S2000, and Philips iU22 in terms of portability, features and functionality." The document provides detailed tables for each transducer type (Curvilinear, Phased Array, Endo-Cavity, Linear, Tran-Esophageal, AUX CW) showing the clinical applications and modes of operation. Each table indicates whether an application is a "P" (previously cleared by FDA 510k # 022858, implying equivalence to the existing ZONARE z.one) or "N" (new indication). For "P" indications, the device is considered to perform equivalently to the predicate. For "N" indications, the device is being introduced for those uses, likely based on similarity to other cleared devices or demonstrating safety and basic functionality in non-clinical tests. Examples of supported modes for various transducers include: - B¹ (B-Mode and Harmonic Imaging): P (Previously cleared) or E (Added under Appendix E) or N (New indication) across most applications. - M (M-Mode): P or E or N across most applications. - PWD² (Pulsed Wave Doppler and HPRF): P or E or N across most applications. - CWD (Continuous Wave Doppler): P or N for specific applications (e.g., Fetal, Abdominal, Pediatric, Neonatal Cephalic, Adult Cephalic, Cardiac Adult & Pediatric, Peripheral Vascular for the main system, and specific entries for some transducers). - Color Doppler³ (Color Doppler, Directional Power Doppler, Power Doppler): P or E or N across most applications. - Combined Modes⁴: P or E or N across most applications. - Other⁵,⁸ (e.g., Color M-Mode, Freehand tissue elasticity): P or E or N for relevant applications. The presence of "P" or "E" in these tables fundamentally means that for those indications and modes, the ZONARE z.one Ultra performs equivalently to the already cleared ZONARE z.one (K022858) or other cleared predicate devices. The "N" indications represent new proposed uses for the system or specific transducers, which are deemed safe and effective through substantial equivalence to other devices or non-clinical testing. |
| Safety and Effectiveness Standard Adherence: The device must conform to applicable medical device safety standards. | "The device has been evaluated according to the applicable medical device safety standards for acoustic output, biocompatibility, cleaning, and disinfection effectiveness as well as thermal, electrical, and mechanical safety." "The device conforms to applicable medical device safety standards and compliance for safety and effectiveness is verified through defined evaluation and market surveillance." "ZONARE designs and develops their products according to 21 CFR 820, ISO 13485:2003 quality systems." |
| Predicate Device Features Equivalence: The device must have the same important safety and effectiveness features, design, materials, and construction as predicate devices. | "Additionally, they [ZONARE z.one Ultra and predicate devices] have the same important safety and effectiveness features, as well as design, materials, and construction." |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not applicable. No clinical test set (in the sense of patient data for performance evaluation) was specified as "Clinical Tests: Non Required."
- Data Provenance: Not applicable. No clinical data was used for a test set. The validation relies on substantial equivalence and adherence to safety standards.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
- Not applicable, as no clinical test set requiring expert ground truth was performed for this 510(k) submission.
4. Adjudication Method for the Test Set
- Not applicable, as no clinical test set requiring adjudication was performed.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, What was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
- Not applicable. This document is for a diagnostic ultrasound system, not an AI-assisted device, and no MRMC study was conducted or required.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
- Not applicable. This is not an algorithmic/AI device; it's a hardware system.
7. The Type of Ground Truth Used
- Ground Truth: In the context of this 510(k), the "ground truth" for the device's safety and effectiveness is established by its substantial equivalence to legally marketed predicate devices and its compliance with recognized medical device safety standards. This is not a "ground truth" in the clinical data sense (e.g., pathology, outcomes data). The existing ZONARE z.one (K022858), GE Voluson i (K053435), Philips iU22 (K042540), and Siemens Acuson S2000 (K072786) served as predicates.
8. The Sample Size for the Training Set
- Not applicable. The device is a diagnostic ultrasound system, not an AI/machine learning model that typically undergoes a "training" phase with a dataset.
9. How the Ground Truth for the Training Set was Established
- Not applicable for the same reason as above.
