Trained medical professionals use Contour ProtégéAI as a tool to assist in the automated processing of digital medical images of modalities CT and MR, as supported by ACR/NEMA DICOM 3.0. In addition, Contour ProtégéAI supports the following indications:
• Creation of contours using machine-learning algorithms for applications including, but not limited to, quantitative analysis, aiding adaptive therapy, transferring contours to radiation therapy treatment planning systems, and archiving contours for patient follow-up and management.
• Segmenting anatomical structures across a variety of CT anatomic locations.
• And segmenting the prostate, the seminal vesicles, and the urethra within T2-weighted MR images.
Appropriate image visualization software must be used to review and, if necessary, edit results automatically generated by Contour ProtégéAI.
Indications for use as stated in the FDA summary.
