Diagnostic ultrasonic imaging for abdominal, pediatric, small organ, musculo-skeletal, cardiac, peripheral vascular, transvaginal and trans-rectal applications in B, M, PWD and Color Doppler modes.

Device Description

The Color Doppler Ultrasound Systems are integrated preprogrammed color ultrasound imaging system, capable of producing a resolution intended for clinical diagnostic imaging applications. Their basic function is to acquire ultrasound signal and display the images in the imaging operation modes of B, M, PWD and Color Doppler.

AI/ML Overview

This document describes the Color Doppler Ultrasound System Models mEye1 and mEye2 (K182165) and its substantial equivalence determination to a predicate device. There is no study described within this document that performs a comparative effectiveness study with human readers or standalone algorithm performance, or establishes acceptance criteria based on diagnostic performance.

The acceptance criteria and study described are for non-clinical performance and safety standards, not for the diagnostic accuracy of the ultrasound system's output. The document explicitly states: "No clinical study is included in this submission." This means that no study was conducted to demonstrate the device's diagnostic performance for the specified indications for use, nor were acceptance criteria related to diagnostic performance established or met through a clinical study.

Therefore, many of the requested items cannot be answered given the provided text.

Here's a breakdown of what can be extracted:

1. A table of acceptance criteria and the reported device performance

The "acceptance criteria" here refer to conformance with established medical device safety and performance standards, rather than diagnostic accuracy metrics.

Acceptance Criteria (Standard/Requirement)	Reported Device Performance
IEC 60601-1-2005+A1:2012 (Electrical Safety)	Complied
IEC 60601-1-2:2014 (EMC)	Complied
IEC 60601-2-37:2007 (Performance - Ultrasonic Medical Diagnostic)	Complied
ISO 10993-5:2009 (Biocompatibility - Cytotoxicity)	Complied
ISO 10993-10:2010 (Biocompatibility - Irritation & Sensitization)	Complied
NEMA UD 2-2004 (R2009) (Acoustic Output)	Complied
Software Level	Moderate level of concern

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Not applicable. No clinical test set or data provenance related to diagnostic performance is mentioned. The tests were non-clinical, likely performed in manufacturing facilities.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. No clinical test set or establishment of ground truth by experts for diagnostic performance is mentioned.

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

Not applicable. No clinical test set requiring adjudication for diagnostic performance is mentioned.

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

No, a multi-reader, multi-case comparative effectiveness study was not done. The document explicitly states: "No clinical study is included in this submission." This device is a diagnostic ultrasound system, not an AI-powered CAD (Computer-Aided Detection) or CADx (Computer-Aided Diagnosis) system, so the concept of "human readers improve with AI vs without AI assistance" does not apply here.

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

No, a standalone (algorithm only) performance study was not done. This is a medical imaging device, not an AI algorithm. Its performance is evaluated through compliance with technical and safety standards, and by demonstrating substantial equivalence to a predicate device.

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

Not applicable. For the non-clinical tests conducted, the "ground truth" was established by the technical specifications and requirements of the referenced standards (e.g., whether the device successfully met electromagnetic compatibility limits, or whether biocompatibility tests showed no cytotoxicity). There was no clinical ground truth established for diagnostic accuracy.

8. The sample size for the training set

Not applicable. This document describes a medical imaging device, not an AI/ML algorithm that requires a training set.

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

Not applicable. See point 8.

Dear Diana Hong:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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 (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

The operation modes of the proposed device do not contain CWD and 3D imaging modes, which is different from that of predicate. There are only two types of probes in proposed device, which are less than that of predicate device. And it is not known whether the predicate device can be powered by battery or DC. However, the proposed device has been demonstrated that comply with requirements of electrical safety, EMC, performance and acoustic output. Therefore, the differences do not impact the safety and effectiveness.

Substantially Equivalent (SE) Conclusion 9.

Based on the comparison and analysis above, the proposed device is determined to be Substantially Equivalent (SE) to the predicate devices.
