RTist is a software application, intended to display and visualize 2D & 3D multimodality (i.e. CT, MRI, and PET) medical image data. The user may process, render, review, store, print and distribute DICOM 3.0 compliant medical image data within the system and/or across computer networks at distributed locations utilizing standard PC hardware.

The volume and linear measurement functions are intended for evaluation and quantification of tumor measurements, location/displacement study, analysis and evaluation of both hard and soft tissues. The software also supports interactive segmentation of the region of interest (ROI), automated contouring of multi-slice ROI and labeling of 'avoidance' structure(s) during critical evaluation.

Typical users of this system are trained professionals, including but not limited to radiologists, clinicians and technicians. When interpreted by a trained physician, reviewed images may be used as an element for diagnosis.

Indications for use as stated in the FDA summary.
