SCT-7000TS
This is a 510(k) clearance letter for the Shimadzu Whole Body x-ray Computed Tomography Scanner SCT-7000TS, dated May 2, 1998. The letter states that the device is substantially equivalent to a predicate device marketed prior to May 28, 1976. This document does not provide details of acceptance criteria or a study proving the device meets acceptance criteria as would be found in a modern AI/ML device submission.
Here's why the requested information cannot be extracted from this document:
- Date: This document is from 1998. The FDA's regulatory framework and submission requirements for medical devices, particularly concerning performance studies and validation for software-driven or AI/ML components, were significantly different and less detailed than they are today.
- Device Type: The device is a "Whole Body x-ray Computed Tomography Scanner." While it is an imaging device, the focus of 510(k) submissions for such devices in 1998 was on demonstrating substantial equivalence to a predicate device, primarily in terms of safety and effectiveness related to its physical parameters, image quality, and intended use, rather than complex algorithm performance.
- Content of 510(k) Letter: This is the clearance letter from the FDA, not the original 510(k) submission itself. It primarily states the FDA's decision and the regulatory class. The actual submission, if available, might contain some performance data, but it is highly unlikely to include the specific types of studies (MRMC, standalone AI performance data) and detailed ground truth methodologies that are common in modern AI/ML device submissions.
Therefore, I cannot provide the requested information. The document pertains to a traditional CT scanner from 1998 and does not describe acceptance criteria or a study in the context of AI/ML performance.

Dear Mr. Fishback:
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 (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 (OS) 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 531 through 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 predication 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 (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. 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 (800) 638-2041 or (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrh/dsmaldsmamain.html".
