FDA approves first mobile diagnostic viewing app

CMIO

February 4, 2011

The FDA has cleared Mobile MIM, a radiology application that allows physicians to view medical images on the iPhone and iPad.

The application is the first cleared by the FDA for viewing images and making medical diagnoses based on CT, MRI and PET. It is not intended to replace full workstations and is indicated for use only when there is no access to a workstation, the agency stated.

Radiology images taken in the hospital or physician’s office are compressed for secure network transfer then sent to the appropriate portable wireless device via Mobile MIM software. Manufactured by Cleveland-based MIM Software, the software allows the physician to measure distance on the image and image intensity values and display measurement lines, annotations and regions of interest.

In its evaluation, the FDA reviewed performance test results on various portable devices. These tests measured luminance, image quality (resolution) and noise in accordance with international standards and guidelines. The FDA said it also reviewed results from demonstration studies with qualified radiologists under different lighting conditions. All participants agreed that the device was sufficient for diagnostic image interpretation under the recommended lighting conditions.

The display performance of mobile devices can experience significant variations in luminance levels even between mobile devices of the same model. The Mobile MIM application includes sufficient labeling and safety features to mitigate the risk of poor image display due to improper screen luminance or lighting conditions. The device includes an interactive contrast test in which a small part of the screen is a slightly different shade than the rest of the screen. If the physician can identify and tap this portion of the screen, then the lighting conditions are not interfering with the physician’s ability to discern subtle differences in contrast. In addition, a safety guide is included within the application.
