syngo TrueD is a medical diagnostic application for viewing, image manipulation, 3D visualization and comparison of medical images. syngo TrueD is intended for combining datasets from multiple imaging modalities and/or multiple time-points into a single dataset that accurately represents the information from the initial data. The input datasets could be functional 3D volumes (e.g. PET and SPECT) and/or anatomic 3D volumes (e.g. CT and MR). This “fusion” of data may be viewed in a number of output formats including MIP and volume rendering.

syngo TrueD enables visualization of information that would otherwise have to be visually compared disjointedly. syngo TrueD provides analytical tools to help the user assess, and document any changes in morphological or functional activity at diagnostic and therapy follow-up examinations. syngo TrueD is designed to support the oncological workflow by helping the user to confirm the absence or presence of lesions, including evaluation, quantification, follow-up and documentation of any such lesions.

Note: The clinician retains the ultimate responsibility for making the pertinent diagnosis based on their standard practices and visual comparison of the separate unregistered images. syngo TrueD is a complement to these standard procedures.

Indications for use as stated in the FDA summary.
