Device Description

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.

AI/ML Overview

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.
