VERIQA RT Monte Carlo 3D: 3D dose calculation with SciMoCa

"Secondary dose calculation systems should be completely independent from primary TPS. Accurate matching between the secondary dose calculational systems and the dosimetric characteristics of the linac is thereby essential for truly independent and valuable dose evaluation"

Prof. Sotiri Stathakis, Ph.D.
University of Texas Health Science
Center, San Antonio

VERIQA RT Monte Carlo 3D

Advanced 3D back-projection approach

“The EPID dose back-projection algorithm of VERIQA RT EPID 3D will offer a double benefit.
It will verify treatment delivery by using in vivo EPID measurements as well as increase efficiency in pre-treatment verification by using EPID images acquired “in air”, thus eliminating the need for phantom positioning and re-planning.”

AIQUALIS Software

Monitor your AI contouring quality in clinical practice.
Streamline your clinical contouring workflows.

Improve AI safety and equality.

Al contouring models are constantly being improved to make them more accurate and robust.
AIQUALIS allows you to identify potential source bias associated with AI-based contouring by allowing you to view results by patient groups or clinical teams. AIQUALIS also allows you to detect automation bias or unexpected changes in the AI contouring model.
Performing QA of your AI-based contouring with AIQUALIS can increase your confidence that your patients are receiving care with all the benefits of safe AI-based contouring.
