syngo.via RT Image Suite

Boosting efficiency

Radiation therapy is a dynamic and fast-changing field. The number of patients receiving this type of therapy is continually rising. Software applications have a key role to play here and can support efficient workflows and deliver precision for advanced therapies, they will drive clinical excellence in RT today and into the future.

syngo.via RT Image Suite was developed for radiation oncology professionals. Designed as a user-friendly work aid to make simulation, image assessment, and contouring easier and better integrated. It simplifies and standardizes daily tasks, and gives you the capabilities you need to go beyond the current standard.

Ease what you do. Seize new opportunities.

Features & Benefits

Ease what you do

Simulation, data preparation or contouring – routine tasks can suffer from workflows across many systems, manual work or unintuitive tools. Work more efficiently and comfortably with an efficient, flexible, and well integrated tool.

Clinical Use

Blinded evaluation of  autocontouring at Universitätsklinikum Erlangen

Siemens Healthineers autocontouring study results

Study details:
Clinical evaluation of clinical images from 50 patients with a total number of 2,040 organs-at-risk structures. Each resulting OAR was then evaluated by 3 physicians in a blinded study (manually vs. auto-contoured clinical images).8

Dose Distribution MR-based Synthetic CT

Dose distribution on MR-based Synthetic CT and CT with corresponding DVHs

  • <1% mean dose difference in PTV, GTV, evaluated OAR
  • <0.5% and 1.4% mean dose difference for the brainstem and chiasma respectively

An internal validation of geometric fidelity and HU unit accuracy

The geometric fidelity test was passed with an average symmetric surface distance (ASSD) <1mm for brain and pelvis. For HU accuracy, line profiles from CT and MR-based Synthetic CT of the same patient were compared as shown in the image.
