Testimonials
“Current state of the art enables OAR autosegmentations that are on par with human experts.”10

Dr. Florian Putz
Universitätsklinikum Erlangen, Strahlenklinik, Germany
“We shortened virtual simulation step to an estimated 20 minutes and thereby have saved significant time for the whole radiation therapy department.”10

Stéphane Muraro
Centre de Cancérologie du Grand Montpellier (CCGM), France
“The standardized algorithms [for organs-at-risk contouring] always return consistent results. Manual contouring can vary from user to user, which affects treatment. This is not the case with the software.”10

Manuel Algara López, MD
Hospital del Mar, Barcelona, Spain
Reduce contouring time in complex cases?
Consistent, high-quality contoured images are key for precise radiation therapy planning. The automation of organs-at-risk contouring could help increase consistency while achieving better efficiency.

Optional. Deformable Registration license recommended.
Optional. DirectSPR is available only for Dual Spiral DE, Twin Spiral DE or Dual Source DE (not for TwinBeam DE and photon-counting CT).
Monoenergetic reconstructions at 55 keV of DECT imaging of head and neck SCC result in a significantly superior overall image quality and tumor delineation.
Interactive Spectral Imaging support will only work with a CT Dual Energy license.
Optional. MR-based Synthetic CT is an optional feature available in syngo.via RT Image Suite starting from software version VB60.
Ventilation results produced by syngo.via RT Image Suite should not be used as the sole diagnostic tool.
The case evaluation was conducted with Organs RT on syngo.via RT Image Suite.
The depicted organs are based on the selected organ template.
