## Indications for use
The D2P software is intended for use as a software interface and image segmentation system for the transfer of imaging information from a medical scanner such as a CT scanner to an output file. It is also intended as pre-operative software for surgical planning. 3D printed models generated from the output file are meant for visual, non-diagnostic use.
