The VIAMO Diagnostic Ultrasound System is indicated for the visualization of structures, characteristics and dynamic processes with the human body using ultrasound and to provide image information for diagnosis in the following clinical applications: fetal, abdominal, pediatric, small organs, trans-vaginal, neonatal cephalic, adult cephalic, cardiac, peripheral vascular and musculo-skeletal (both conventional and superficial).

Device Description

Viamo V4.0 is a Track 3 ultrasound system. It is a full-digital system that utilizes a wide range of probes (flat linear array, convex array and sector array) with a frequency range of approximately 2.5 MHz to 12 MHz. The slim pole-cart allows the system to be easily moved in the medical facility to perform examinations. The main unit, which can be detached from the cart by one-touch operation, is powered by an internal battery.

AI/ML Overview

Here's a summary of the acceptance criteria and the study information based on the provided 510(k) summary:

This device (VIAMO MODEL SSA-640A V4.0) is a diagnostic ultrasound system and is primarily demonstrating substantial equivalence to a predicate device (Viamo SSA-640A v2.0 Ultrasound System, K100067) by showing that its new features do not alter the existing indications for use or raise new questions of safety and effectiveness.

1. Table of Acceptance Criteria and Reported Device Performance

For the new features (addition of two transducers and "Vascularity Index"), the acceptance criteria and reported performance are implicitly demonstrated through bench testing to ensure they meet established safety and effectiveness standards, rather than defining specific statistical performance metrics.

Feature	Acceptance Criteria (Implicit)	Reported Device Performance
Added Transducers (PVT-712BT, PST-50BT)	Safe and effective for their indicated clinical applications (trans-vaginal for PVT-712BT; abdominal, pediatric, neonatal cephalic, adult cephalic, cardiac adult, cardiac pediatric for PST-50BT). Performance equivalent to current cleared transducers where applicable.	B-mode accuracy and Doppler mode velocity accuracy confirmed effectiveness. Electrical, thermal, and acoustic power tests confirmed safety. The new transducers do not change the cleared intended use.
Vascularity Index	Accurate display of the area of blood flow in power mode to support diagnostic use.	Accuracy test of the "Vascularity Index" was conducted and confirmed effectiveness. The addition does not change the effectiveness and safety of the device.
New Display Format for Dual Images	Functions as intended without compromising image quality or safety.	Implied to be effective through general safety and effectiveness statement; no specific performance tests mentioned for this particular feature beyond general device safety.

2. Sample Size Used for the Test Set and Data Provenance

Sample Size for Test Set: Not explicitly stated in the provided document. The document refers to "bench tests" and implies that these tests were conducted internally or at the manufacturer's facility to verify the features.
Data Provenance: Not specified. Given that only bench testing was conducted, the "data" would likely be derived from internal engineering and performance measurements. The manufacturer is Panasonic Healthcare Co., Ltd. in Japan.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not applicable. The document states that "Viamo V4.0 did not require clinical studies to support substantial equivalence." Therefore, no ground truth established by clinical experts for a test set is described. The assessment relied on engineering and performance testing against established standards.

4. Adjudication Method for the Test Set

Not applicable, as no clinical test set requiring expert adjudication was conducted.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study was mentioned or conducted. The submission focuses on substantial equivalence based on technical characteristics and bench testing, not on comparing reader performance with and without AI assistance (as the "Vascularity Index" is an image processing feature, not an AI diagnostic tool in the sense of AI/ML-enabled CAD systems).

6. Standalone Performance Study

Not applicable in the typical sense of an "algorithm only" performance study. The "Vascularity Index" is an integrated feature of the ultrasound system, and its "performance" (accuracy) was confirmed via bench testing as part of the overall device functionality rather than as a standalone algorithm evaluated against a separate ground truth in a clinical context.

7. Type of Ground Truth Used

For the added transducers and Vascularity Index: The "ground truth" was established based on engineering and physical measurement standards to confirm accuracy (e.g., B-mode accuracy, Doppler mode velocity accuracy, accuracy of Vascularity Index calculation) and compliance with safety standards (electrical, thermal, acoustic power).

8. Sample Size for the Training Set

Not applicable. This device is an ultrasound system with added features (transducers, image display, and a quantitative index), not a machine learning or AI algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there was no training set for a machine learning algorithm.

Dear Mr. Job:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

This determination of substantial equivalence applies to the following transducers intended for use with the VIAMO MODEL SSA-640A V4.0, as described in your premarket notification:

Transducer Model Number

PST-25ST	PLT-1204BT	PLT-704ST
PVT-375ST	PVT-674BT	PST-50BT
PLT-704ST	PVT-661VT	PVT-712BT
PLT-805AT	PVT-745BTV
PVT-382BT	PVT-705BTH

{4}------------------------------------------------

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please go to http://www.fda.gov/AboutFDA/CentersOffices/CDRH/CDRHOffices/ycm115809.htm for the Center for Devices and Radiological Health's (CDRH's) Office of Compliance.
