The Versana Premier is a general purpose, Track 3, diagnostic ultrasound system for use by qualified and trained healthcare professionals. The system is a mobile console that includes an operator control panel, display monitor and transducers. The console provides digital acquisition, processing and display capability. The system has an internal battery to allow for acquisition while the system is not plugged into a power source. The operator control panel includes function keys, trackball, an alfa-numeric keyboard and a touch panel as input sources of the device. The variety of transducers include convex, linear, sector, dual and mechanical 4D transducers. The access types include trans- body surface, transrectal, transvaginal and transcranial. Data can be imported or exported by DVD, USB, LAN or WiFi if the USB wireless adapter is connected to the system. An external ECG module has been verified to use as input for gating during scanning. The system has a HDMI port, VGA connection port, S-Video port, and a Composite Out port connection. The system has an external AC outlet to allow connection of a printer box of the console and an option for external Printer USB Isolator for other printers to connect. The system supports one way, Bluetooth communication capability from the system to a personal device to allow for sharing of the patient's data/images when the external Bluetooth USB adapter is connected to the system.

The provided text is a 510(k) Premarket Notification Submission for the GE Versana Premier ultrasound system. This document focuses on demonstrating substantial equivalence to existing predicate devices, rather than proving that a new AI-powered diagnostic device meets specific performance acceptance criteria through a dedicated clinical study.

Therefore, the information required to populate the fields related to acceptance criteria, ground truth, sample size, expert adjudication, and comparative effectiveness studies is not present in this document. The document explicitly states: "The subject of this premarket submission, Versana Premier, did not require clinical studies to support substantial equivalence."

The only mention of an "Artificial Intelligence (AI) feature" is "Whizz Label," and no performance data or study details are provided for this feature. The document indicates that the Versana Premier employs "the same fundamental scientific technology as its predicate device and reference devices," and that it is "substantially equivalent ... with regard to intended use, imaging capabilities, technological characteristics, imaging modes, hardware, and safety effectiveness."

Here's what can be extracted from the document regarding the AI feature, acknowledging the absence of the requested study details:

• AI Feature Mentioned: Whizz Label is an Artificial Intelligence (AI) feature that is being added.

All other requested information cannot be found in the provided document:

1. A table of acceptance criteria and the reported device performance: Not provided.
2. Sample sized used for the test set and the data provenance: Not provided.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not provided.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not provided.
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: Explicitly stated that clinical studies were not required.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not provided.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not provided.
8. The sample size for the training set: Not provided.
9. How the ground truth for the training set was established: Not provided.

Vscan Air is a battery-operated software-based general-purpose ultrasound imaging system for use by qualified and trained healthcare professionals or practitioners that are legally authorized by law in the country, state or other local municipality in which he or she practices. The users may or may not be working under supervision or authority of a physician. Users may also include medical students working under the supervision or authority of a physician during their education / training. The device is enabling visualization and measurement of anatomical structures and fluid including blood flow.

Vscan Air's pocket-sized portability and simplified user interface enables integration into training sessions and examinations in professional healthcare facilities (ex. Hospital, clinic, medical office), home environment, road/air ambulance and other environments as described in the user manual. The information can be used for basic/focused assessments and adjunctively with other medical data for clinical diagnosis purposes during routine, periodic follow-up, and triage.

Vscan Air supports Black/ white (B-mode), Color flow (Color doppler), Combined (B + Color Doppler) and Harmonic imaging modes with both the curved and linear array transducers.

With the curved array transducer of the dual headed probe solution, the specific clinical applications and exam types include: abdominal, fetal/obstetrics, gynecological, urology, thoracic/lung, cardiac (adult and pediatric, 40 kg and above), vascular/peripheral vascular, musculoskeletal (conventional guidance (includes free hand needle/catheter placement, fluid drainage, nerve block and biopsy).

With the linear array transducer of the dual headed probe solution, the specific clinical applications and exam types include: vascular/peripheral vascular, musculoskeletal (conventional and superficial), small organs, thoraciclung, ophthalmic, pediatrics, neonatal cephalic, interventional guidance (includes free hand needle/catheter placement, fluid drainage, nerve block, vascular access and biopsy).

Vscan Air™ is a battery-operated general-purpose diagnostic ultrasound imaging system for use by qualified and trained healthcare professionals. It enables ultrasound imaging guidance, visualization and measurement of anatomical structures and fluid.
Vscan Air consists of an app which can be installed on Android™ or iOS devices, and a probe which uses wireless technology for communication.

Its pocket-sized portability and simplified user interface enable integration into training sessions and examinations in professional healthcare facilities (ex. Hospital, clinic, medical office), home environment, road/air ambulance and in other environments. The information can be used for basic/focused assessments and adjunctively with other medical data for clinical diagnosis purposes during routine, periodic follow-up, and triage assessments for adult, pediatric and neonatal patients. Vscan Air can also be useful for interventional guidance.

The provided document indicates that the Vscan Air device did not require clinical studies to support substantial equivalence. Therefore, there is no detailed information regarding acceptance criteria, device performance, sample sizes for test or training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment for a study proving the device meets acceptance criteria.

The document primarily focuses on non-clinical tests to demonstrate substantial equivalence to predicate devices. These non-clinical tests pertain to acoustic output, biocompatibility, cleaning and disinfection, as well as thermal, electrical, electromagnetic, mechanical safety, and wireless communication. The device was found to conform to applicable medical device safety standards.

Summary of Non-Clinical Tests and Conformance:

Key takeaway regarding clinical studies:

• Clinical Studies: "The subject of this premarket submission, Vscan Air, did not require clinical studies to support substantial equivalence."

Therefore, the requested information regarding a study proving acceptance criteria for clinical performance is not available in the provided text. The submission relied on non-clinical testing and comparison to predicate devices to establish substantial equivalence.
