More Information

Not Found

No
The summary describes standard medical image viewing and manipulation software features (DICOM viewing, 3D rendering, virtual endoscopy) and explicitly states "Mentions AI, DNN, or ML: Not Found". There is no mention of AI/ML in the intended use, device description, or performance studies.

No
The device is described as a software package for viewing and manipulating medical images, which is diagnostic in nature, not therapeutic. It does not exert any direct treatment or therapy on a patient.

No.
The device is described for "viewing and manipulating DICOM-compliant medical images" and "real-time image viewing, image manipulation, 3D volume rendering, virtual endoscopy, and issuance of reports," but it does not claim to provide a diagnosis or aid in making a diagnosis.

Yes

The device description explicitly states "REX™ 1.0 is a software package" and "The proposed software provides..." without mentioning any accompanying hardware components that are part of the regulated device. The performance studies focus on software validation and DICOM conformance.

Based on the provided information, REX™ 1.0 is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVDs are used to examine specimens from the human body. The intended use and device description of REX™ 1.0 clearly state that it is for viewing and manipulating medical images acquired from CT scanners. This is an in-vivo (within the living body) imaging modality, not an in-vitro (outside the living body) diagnostic test.
  • The functions described are image processing and visualization. REX™ 1.0 performs tasks like real-time image viewing, manipulation, 3D rendering, and virtual endoscopy. These are all related to processing and presenting medical images, not analyzing biological samples.

Therefore, REX™ 1.0 falls under the category of medical imaging software, not an in vitro diagnostic device.

§ 892.2050 Medical image management and processing system.

(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)

Product Code: 90 LLZ Dated: April 3, 2002 Received: April 4, 2002

Dear Mr. Anderson:

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.

5

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), please contact the Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter:
