The DC-7 Diagnostic Ultrasound System is applicable for adults, pregnant women, pediatric patients and neonates. It is intended for use in abdominal, cardiac, small organ (breast, testes, thyroid, etc.), peripheral vascular, fetal, transvaginal, pediatric, transcranial (adult cephalic and neonatal cephalic), musculoskeletal (conventional and superficial), intraoperative, and urology exams.
The DC-7 Diagnostic Ultrasound System is a general purpose, portable, software controlled, ultrasound diagnostic system. Its function is to acquire and display ultrasound images in B-mode, M-mode, Color mode, Color M mode, CW mode, CW mode, Power/DirPower mode, TDI mode or the combined mode (i.e. B/M Mode). This system is a Track 3 device that employs an array of probes that include linear array probe, convex array probe, phased array probe and volume probe with a frequency range of approximately 1.8 MHz to 12.0 MHz. This modification will provide users with 3 additional transducers, some additional optional features called STIC, Stress Echo, iPage, and etc. These modifications all lead to overall quality and image enhancement.
The DC-7 Diagnostic Ultrasound System is a general purpose ultrasound system with various transducers and modes of operation. The provided text is a 510(k) summary for this device, seeking substantial equivalence to predicate devices, and outlines its intended use, non-clinical tests, and technological characteristics. The document does not contain specific acceptance criteria and a study proving the device meets those criteria in the way typically expected for an AI/CADe device.
Instead, the document details the Indications for Use (IFU) for the DC-7 Diagnostic Ultrasound System and its various transducers across different clinical applications and modes of operation. The "acceptance criteria" here are implicitly that the new system and its transducers can perform these functions ("P" for previously cleared, "N" for new indications) safely and effectively, demonstrating substantial equivalence to the listed predicate devices.
Here's a breakdown based on your request, interpreting "acceptance criteria" as the claimed capabilities and "study" as the information provided for regulatory clearance:
1. Table of Acceptance Criteria and Reported Device Performance
Since this is a 510(k) clearance for a general-purpose ultrasound system and not a specific AI/CADe algorithm with performance metrics like sensitivity/specificity, the "acceptance criteria" are the claimed modes of operation and clinical applications for each transducer. The "reported device performance" is that the system and transducers are capable of these indicated uses, demonstrating substantial equivalence to predicate devices.
The tables for each transducer (e.g., 3C5A, C5-2, V10-4, L12-4, P7-3, etc.) list the following "acceptance criteria" (indicated by 'P' for previously cleared or 'N' for new) and their reported performance (the presence of 'P' or 'N' in the table signifies the device meets these criteria for the given transducer):

P = Previously cleared by FDA; N = New indication (for this specific K-number, it implies new to this device or transducer combination)
Entries are filled based on the collective information from all transducer tables where "P" or "N" is indicated for at least one transducer. Some specific cells might be blank for certain transducers, meaning that mode/application is not indicated for that specific transducer.
The "study" proving these criteria are met is the "Non-clinical Tests" and the demonstration of "Technological Characteristics" being substantially equivalent to predicate devices.
2. Sample Size Used for the Test Set and the Data Provenance
- The 510(k) summary does not describe a specific "test set" in terms of patient data for a clinical study comparing performance metrics.
- Instead, the submission relies on non-clinical tests (acoustic output, biocompatibility, cleaning/disinfection, thermal/electrical/mechanical safety) and comparison of technological characteristics to predicate devices to establish substantial equivalence.
- Data provenance: Not applicable in the context of a clinical test set from patient data. The provenance for the non-clinical tests would be internal laboratory testing by the manufacturer.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
- Not applicable. This is a clearance for a general diagnostic ultrasound system based on technological equivalence and safety standards, not an AI/CADe device requiring expert-established ground truth for a clinical performance study.
4. Adjudication Method for the Test Set
- Not applicable, as no clinical test set requiring expert adjudication is described in the provided summary.
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 not an AI/CADe device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
- Not applicable. This is not an AI/CADe device.
7. The Type of Ground Truth Used
- Not applicable. The clearance is based on adherence to medical safety standards (IEC, ISO), acoustic output, biocompatibility, and demonstrated technological equivalence to legally marketed predicate devices, rather than comparison to a clinical ground truth like pathology or outcomes data for a specific diagnostic task.
8. The Sample Size for the Training Set
- Not applicable. This is a hardware/software system, not an AI/CADe algorithm requiring a training set from patient data in the context of medical imaging.
9. How the Ground Truth for the Training Set Was Established
- Not applicable. As above, this is not an AI/CADe algorithm with a training set.
In summary: The provided 510(k) summary for the Mindray DC-7 Diagnostic Ultrasound System is for a general-purpose diagnostic imaging device, not an AI or CADe product. Therefore, the "acceptance criteria" and "study" described align with the requirements for establishing substantial equivalence for such a device, focusing on safety, performance, and technological similarity to already cleared predicate devices, rather than detailed performance metrics from clinical trials or AI algorithm validation.

The provided text is a 510(k) summary for the Mindray DC-3/DC-3T Diagnostic Ultrasound System. It is a declaration of substantial equivalence to previously cleared devices, rather than a study outlining acceptance criteria and device performance. As such, the input does not contain the information needed to directly answer all parts of your request.
Here's an analysis based on the available information:
1. Table of Acceptance Criteria and Reported Device Performance:
The document is a 510(k) summary, which a regulatory submission to demonstrate that a new device is as safe and effective as a legally marketed predicate device. This type of submission does not typically include a table of acceptance criteria or quantitative performance metrics from a specific study designed to prove the device meets these criteria. Instead, it asserts equivalence based on technological characteristics and adherence to safety standards.
2. Sample Size Used for the Test Set and Data Provenance:
No studies with a "test set" are described, nor is there information about sample sizes or data provenance (e.g., country of origin, retrospective/prospective). The 510(k) relies on comparison to existing predicate devices and compliance with recognized standards.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
Since no specific study evaluating the device's diagnostic performance against a ground truth is described, there is no information on the number or qualifications of experts used for establishing ground truth.
4. Adjudication Method for the Test Set:
No adjudication method is mentioned as no specific test set-based study is presented.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done:
No MRMC comparative effectiveness study is described in this 510(k) summary. The document focuses on establishing substantial equivalence based on technological characteristics and adherence to safety standards, not on demonstrating improved human reader performance with AI assistance.
6. If a Standalone Study (Algorithm Only Without Human-in-the-Loop Performance) Was Done:
This device is a general-purpose diagnostic ultrasound system, not an AI-powered algorithm. Therefore, a standalone algorithm-only study is not applicable and not mentioned. The declaration is for the complete ultrasound system.
7. The Type of Ground Truth Used:
No ground truth is mentioned as no specific diagnostic performance study is presented. The "ground truth" in a 510(k) for a general ultrasound system is typically considered to be compliance with established safety and performance standards for diagnostic ultrasound and equivalence to predicate devices.
8. The Sample Size for the Training Set:
This information is not applicable. The device is a traditional ultrasound system, not an AI model that requires a training set of data.
9. How the Ground Truth for the Training Set Was Established:
This information is not applicable for the same reasons as (8).
Summary of available information from the document:
- Acceptance Criteria/Performance: The submission claims the device "has been found to conform with applicable medical safety standards" (UD 2, UD 3, IEC 60601-1, IEC 60601-1-1, IEC 60601-1-2, IEC 60601-2-37, IEC 60601-1-4, ISO 10993-1, and IEC 62304) and is "substantially equivalent" to predicate devices (Mindray DC-7(K101041), Mindray DC-3/DC-3T (K091941) and Mindray M5(K102991)). This implies that the 'acceptance criteria' are primarily regulatory compliance and demonstration of equivalence to existing devices.
- Study Design: This is a 510(k) summary, which is a regulatory submission asserting substantial equivalence, not reporting a clinical study with detailed performance metrics. It does not describe a clinical study in the format one might expect for device performance evaluation against specific metrics.
- Intended Use: The device is broadly applicable for adults, pregnant women, pediatric patients, and neonates for various exams including gynecology, obstetrics, abdominal, cardiac, vascular, and small parts.
- Transducers: A list of compatible transducers (3C5A, 6C2, 7L5, 6CV1, 6LE7, 7LT4, 7L4A, 6LB7, D6-2, 7L6, 3C1, 10L4, 2P2) is provided, each with specific "Indications for Use" forms detailing the clinical applications and modes of operation they support.
