The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the description focuses on standard image viewing and manipulation techniques.
No
The device is described as a software package for viewing and manipulating medical images, intended for diagnostic rather than therapeutic purposes. Its functions include image viewing, manipulation, 3D rendering, virtual endoscopy, and report issuance, none of which directly administer therapy.
No
The device is described as a software package for viewing and manipulating medical images, and issuing reports, not for providing a diagnosis itself. It is a tool used in the diagnostic process by healthcare professionals, but it doesn't perform the diagnosis.
Yes
The device is described as a "software package" and a "tool for 3D and 2D viewing and manipulation of DICOM compliant CT and MR images," with no mention of accompanying hardware components. Its functions are purely software-based image processing and reporting.
Based on the provided information, this device 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 clearly state that REX™ 3.0 is for viewing and manipulating medical images acquired from CT and MR scanners. These are images of the human body itself, not specimens taken from it (like blood, urine, tissue samples, etc.).
- The purpose is image viewing and manipulation for diagnostic interpretation. While the software aids in the diagnostic process by allowing physicians to view and manipulate images, it does not perform tests on biological samples to provide diagnostic information.
Therefore, REX™ 3.0 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)

Dear Mr. Bonk:
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. Iisting 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 r 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.
