AI/ML Overview

This document is an FDA 510(k) clearance letter for a medical device called the "Mark I Thermal Imager." It primarily discusses regulatory approval and does not contain detailed information about the acceptance criteria and the study that proves the device meets those criteria. The letter confirms that the device is substantially equivalent to a legally marketed predicate device, but it does not provide the specifics of the performance testing or clinical studies.

Therefore, I cannot fulfill your request for the information outlined in your prompt using only the provided text. The document does not contain:

1. A table of acceptance criteria and reported device performance.
2. Sample sizes or data provenance for a test set.
3. Information on experts used to establish ground truth.
4. Adjudication method for a test set.
5. Details of a multi-reader multi-case (MRMC) comparative effectiveness study.
6. Information on a standalone algorithm performance study.
7. The type of ground truth used.
8. Sample size for a training set.
9. How ground truth for the training set was established.

The "Indications for Use" section (page 2 of the input) briefly describes the purpose of thermal imaging as an "adjunctive procedure to support other diagnostic modalities" and its ability to "demonstrate a temperature variance as a method to help clarify findings indicated by mammography or some other diagnostic procedure." However, this is a statement of intended use, not a report of study results or acceptance criteria.

To obtain the information you are looking for, you would typically need to consult the 510(k) premarket notification submission itself, which would contain the detailed study results and performance data.

Trade/Device Name: Mark I Thernal Imager Regulation Number: 21 CFR 884.2980 Regulation Name: Telethermographic system Regulatory Class: I Product Code: 90 LHQ Dated: November 19, 2002 Received: November 25, 2002

Dear Mr. O'Neil:

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. 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 (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.

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.

{1}------------------------------------------------

This letter will allow you to begin marketing your device as described in your Section 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), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of the letter:

8xx.1xxx	[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" (21CFR Part 807.97) you may obtain. Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number [phone] or [phone] or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html.

INDICATIONS FOR USE

Thermal Imaging is a medical imaging modality for use as an adjunctive procedure to support other diagnostic modalities. For example, thermal imaging of breasts can demonstrate a temperature variance as a method to help clarify findings indicated by mammography or some other diagnostic procedure.

Thermal imaging in general is a determination of physiologic rather than anatomic change. Neoangioenesis accompanies turnor growth and typically produces an alteration in blood vessels. Any changes in blood vessel activity generally introduce a change in temperature in the immediate area of the affected blood vessel.

Thermography is incapable of visualizing anatomic matter unless it is accompanied by an alteration in surface temperature. Hence, thermography is an adjunctive medical imaging modality.

Regulation Number and Section

§ 884.2980 Telethermographic system.

(a)
Telethermographic system intended for adjunctive diagnostic screening for detection of breast cancer or other uses —(1)Identification. A telethermographic system for adjunctive diagnostic screening for detection of breast cancer or other uses is an electrically powered device with a detector that is intended to measure, without touching the patient's skin, the self-emanating infrared radiation that reveals the temperature variations of the surface of the body. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(2)
Classification. Class I (general controls).(b)
Telethermographic system intended for use alone in diagnostic screening for detection of breast cancer or other uses —(1)Identification. A telethermographic system for use as the sole diagnostic screening tool for detection of breast cancer or other uses is an electrically powered device with a detector that is intended to measure, without touching the patient's skin, the self-emanating infrared radiation that reveals the temperature variations of the surface of the body. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(2)
Classification. Class III.(3)
Date PMA or notice of completion of a PDP is required. As of the enactment date of the amendments, May 28, 1976, an approval under section 515 of the act is required before the device described in paragraph (b)(1) may be commercially distributed. See § 884.3.
