The Sonosite Diagnostic Ultrasound Systems are full featured, general purpose, software controlled, diagnostic ultrasound system used to acquire and display high-resolution, real-time ultrasound data through multiple imaging modes. They are intended to be used for general purpose ultrasound examination, cardiac imaging, fetal imaging and OB/GYN applications, vascular imaging and trans-rectal applications and fluid flow analysis among others. Some Sonosite Ultrasound Systems (Sonosite PX) also have needle guidance capabilities. They are intended to be used by qualified physicians and trained professionals in various patient care settings including hospitals, clinics, and point-of-care settings. Software modes/applications, scanning protocols, and pre-installed settings or functionality to create dedicated settings for imaging of specific anatomy are available with the subject Sonosite Ultrasound Systems and may vary among the different model configurations. The Sonosite Ultrasound Systems work on either battery or AC power. Some Sonosite Diagnostic Ultrasound Systems support Bluetooth and wireless connectivity for image transfer and over-the-air (OTA) software updates. The diagnostic ultrasound systems are manufactured with hardware components which consist of: 1) a primary console (e.g., workstation, tablet with touchscreen) with built-in software components, features, and various clinical applications, and 2) a range of compatible ultrasound transducers. A suite of compatible transducers are offered with the Sonosic Ultrasound Systems. These include linear array, curved array, phased array, intra-cavitary, static probes and trans-esophageal transducers. Linear array transducers (prefixed with the letter L) produce a rectangular field of view with uniform beam density throughout and are useful for imaging shallow structures and small parts. Curved array transducers (prefixed with the letter C) allow for a wider field of vith decreased line density at depth and reduced lateral resolution. They are the ideal probe for lung ultrasound imaging. Phased array transducers (prefixed with the letter P) are small faced transducers allowing for imaging in small spaces. They are able to change the focus of the ultrasound beam. It is the optimal transducer recommended for cardiac imaging. Trans-esophageal transducers (prefixed with the letters TE) are commonly used for evaluation of cardiac and aortic structures. Intra-cavitary transducers (prefixed with the letters IC) are used for trans-rectal ultrasounds. Some models may have additional previously-cleared accessories, or components which are manufactured by other manufacturers.

The provided document is a 510(k) Summary for multiple FUJIFILM Sonosite Diagnostic Ultrasound Systems. It primarily focuses on demonstrating substantial equivalence to previously cleared predicate devices. The document explicitly states: "Relevant performance data does not apply to this submission. Design control measures described within the submission support a decision of substantial equivalence."

Therefore, the document does not include a study or acceptance criteria related to a new device or algorithm performance evaluation. Instead, it relies on the predicate devices' established safety and effectiveness. The modifications mentioned are primarily "Additional user labeling ... for patients with coronavirus disease 2019 (COVID-19)" based on existing methods or society guidelines, not a new AI-powered diagnostic feature.

Given this, I cannot provide the requested information about acceptance criteria, device performance, sample sizes, ground truth, experts, or MRMC studies, as these types of studies were explicitly stated as not applicable to this submission.

This device is indicated for Prescription Use Only.

The Sonosite PX Ultrasound System is intended to be used in medical practices, clinical environments, including Healthicare facilities, Hospitals, Clinics and clinical point-of-care for diagnosis of patients.

The Sonosite PX Ultrasound System is a full featured, general purpose, software controlled, diagnostic ultrasound system used to acquire and display high-resolution, real-time ultrasound data in 2D, M-Mode (including Simultaneous M-Mode), Pulsed Wave (PW) Doppler (including Pulsed Wave Tissue Doppler), Continuous Wave (CW) Doppler, Color Power Doppler (including Velocity Color Doppler), Tissue Harmonic Imaging or in a combination of these modes. The Sonosite PX Ultrasound System also includes needle guidance capability. The system is capable of working with two different types of needle guide brackets available, including 1) Fixed-angle, in-plane brackets where a pair of guidelines are generated that represent the path of the needle and 2) Transverse-angle, out-of-plane brackets (adjustable depths) where the quidelines appear down the center of the imaqe. Each Sonosite PX transducer has an appropriate needle quide bracket kit to support needle quidance with the system.

The provided text is a 510(k) Pre-Market Notification for the FUJIFILM SonoSite PX Ultrasound System. It focuses on demonstrating substantial equivalence to existing predicate devices (SonoSite Edge II Ultrasound System and SonoSite X-Porte Ultrasound System) rather than presenting a study to prove acceptance criteria for a new AI/algorithm-based diagnostic device.

Therefore, many of the requested details about acceptance criteria, device performance metrics, sample sizes, ground truth establishment, and comparative effectiveness studies are not applicable as they are specific to studies evaluating the performance of diagnostic algorithms.

However, I can extract and summarize the information that is present:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not provide a table of acceptance criteria with specific performance metrics (e.g., sensitivity, specificity, AUC) for an AI or algorithmic function. Instead, it demonstrates substantial equivalence to predicate devices based on technological characteristics and compliance with safety standards.

The "reported device performance" in this context refers to the device's ability to perform various ultrasound imaging modes across different clinical applications, which is considered equivalent to the predicate devices.

2. Sample size used for the test set and data provenance:

• Not Applicable. The document explicitly states: "The Sonosite PX Ultrasound System and transducers, subject of this submission, did not require clinical studies to support the determination of substantial equivalence." Non-clinical tests were conducted for safety and technological characteristics, not for clinical performance evaluation comparable to an AI algorithm's test set.

3. Number of experts used to establish the ground truth for the test set and qualifications of those experts:

• Not Applicable. No clinical test set requiring expert ground truth was conducted for this submission. The device is a general-purpose ultrasound system, and its functionality relies on the interpretation of images by qualified healthcare professionals.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

• Not Applicable. No clinical test set requiring adjudication was performed.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs. without AI assistance:

• Not Applicable. This is a submission for a general-purpose ultrasound imaging system, not an AI-assisted diagnostic algorithm. Therefore, no MRMC study comparing human readers with and without AI assistance was conducted or mentioned.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• Not Applicable. This device is an imaging system, not a standalone algorithm. Its intended use is for qualified physicians and healthcare professionals to perform evaluations using the ultrasound images.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Not Applicable. As no clinical studies were performed to establish performance metrics for a diagnostic algorithm, no specific ground truth type was established for that purpose. The "ground truth" for demonstrating substantial equivalence was conformity to recognized safety standards and verification of technological functionality against predicate devices.

8. The sample size for the training set:

• Not Applicable. This device is an ultrasound system. While it includes "software controlled" elements and features like "Speckle reduction algorithm" and "SonoMB/MBe Image Compounding," these are traditional image processing techniques inherent to ultrasound technology, not machine learning algorithms that would require a distinct "training set" in the modern AI sense.

9. How the ground truth for the training set was established:

• Not Applicable. See point 8.
