The summary describes image viewing, processing, and analysis software, but does not mention AI or ML capabilities. The "Mentions AI, DNN, or ML" field is explicitly "Not Found".
No
Explanation: The device is described as a software package designed for viewing, processing, and analyzing medical image data (specifically mammography) to assist radiologists in screening and diagnosis. It does not provide any form of treatment or therapy.
Yes
The device is described as a "mammography review workstation software package" and is "designed to assist the radiologist in conducting screening and primary diagnosis". It explicitly states that "When interpreted by a skilled physician, this software provides information that may be useful in screening and diagnosis." These functions directly support the process of diagnosing medical conditions based on medical images.
No
While the device is described as a "software product," the Device Description explicitly states that the "hardware configuration used with the software typically will include a PC, a single standard color monitor, a multi-function keypad, and two high resolution monitors for mammographic Image review." This indicates that specific hardware components are considered part of the overall system for the intended use, even if the submission focuses on the software.
Based on the provided information, the DexTop Mammography Workstation is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The DexTop Mammography Workstation processes and displays medical images (MG, MR, CR, US), which are generated by imaging equipment and represent the internal structure of the body, not biological specimens like blood, urine, or tissue samples.
- The intended use is for image review, processing, and analysis to assist in diagnosis. While this is a diagnostic aid, it operates on image data, not biological samples.
- The device description focuses on software for image handling and display. It describes receiving digital image data and providing tools for viewing and processing.
In summary, the DexTop Mammography Workstation is a medical image processing and review workstation, which falls under the category of medical devices, but not specifically In Vitro Diagnostics.
N/A
Intended Use / Indications for Use
The DexTop Mammography Workstation is a mammography review workstation software package, which provides very high performance viewing, processing and analysis of multimodality two and three dimensional, as well as planar, medical image data.
The DexTop Workstation is designed to assist the radiologist in conducting screening and primary diagnosis through flexible, fast and efficient image hanging and processing of multimodality softcopy images with special emphasis and optimization for mammography.
When interpreted by a skilled physician, this software provides information that may be useful in screening and diagnosis. However, the final judgment must rely on the knowledge and skill of the physician.

Dear Mr. Sall:
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 such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Rarts 800 to 898.

Device Name: Dexela DexTop Mammography Workstation
The DexTop Mammography Workstation is a mammography review workstation software package, which provides very high performance viewing, processing and analysis of multimodality two and three dimensional, as well as planar, medical image data.
The DexTop Workstation is designed to assist the radiologist in conducting screening and primary diagnosis through flexible, fast and efficient image hanging and processing of multimodality soft-copy images with special emphasis and optimization for mammography.
Dexela DexTop Mammography Workstation will display the full fidelity DICOM image in a non-compressed format. Lossy compressed mammography images and digitized film screen images must not be used for the purpose of primary diagnosis. Mammographic images may only be interpreted using an FDA approved monitor that offers at least 5 megapixel resolution and meets other technical specifications reviewed and accepted by the FDA
When interpreted by a skilled physician, this software provides information that may be useful in screening and diagnosis. However, the final judgment must rely on the knowledge and skill of the physician.
The device will display only DICOM "For Presentation" images for primary image diagnosis. The device does not perform any image processing (except simple manipulation such as gray scale changes by window level and window width) of the proprietary image processing algorithm of the FFDM manufacturers.
