AI/ML Overview

This FDA 510(k) clearance letter (K981880) for the DX-480 Add-on Digital Imager determines substantial equivalence to a predicate device. However, the provided document does not contain any information regarding acceptance criteria, device performance metrics, or details of a study used to validate the device's performance.

The letter primarily focuses on:

• Confirming the review of the 510(k) notification.
• Determining substantial equivalence to a legally marketed predicate device.
• Outlining regulatory classifications and general controls applicable to the device.
• Providing contact information for regulatory compliance.

Therefore, I cannot fulfill your request for:

1. A table of acceptance criteria and reported device performance.
2. Sample size used for the test set and data provenance.
3. Number and qualifications of experts for ground truth.
4. Adjudication method.
5. MRMC comparative effectiveness study details.
6. Standalone performance study details.
7. Type of ground truth used.
8. Sample size for the training set.
9. How ground truth for the training set was established.

This information would typically be found in the 510(k) summary or other supporting documentation submitted to the FDA, which is not included in the provided text.

Dear Mr. Andres:

We have reviewed your Section 510(k) 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 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). 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), 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. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) 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 the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled. "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number [phone] or [phone] or at its finternet address "http://www.fda.gov/cdr/dsmaldsmamain.html".

Sincerely yours,
