## Indications for use
Microsoft Radiomics App v1.0 is a software-only medical device intended for use by trained radiation oncologists, dosimetrists and physicists to derive optimal organ and tumor contours for input to radiation treatment planning. Supported image modalities are Computed Tomography and Magnetic Resonance. Radiomics App assists in the following scenarios: • Load, save and display of medical images and contours for treatment evaluation and treatment planning. • Creation, transformation, and modification of contours for applications including, but not limited to: transferring contours to radiotherapy treatment planning systems, aiding adaptive therapy, and archiving contours for patient follow-up. • Localization and definition of both solid tumors and healthy anatomical structures. • Fusion display of compatible images for treatment planning. • Three-dimensional rendering of medical images and the segmented contours. Images reviewed using the Radiomics App software should not be used for primary image interpretations. Radiomics App is not for use with digital mammography.
