Comprehensive AI contouring solution

Contour+ encompasses all major anatomical sites and treatment planning structures with state-of-the-art 3D AI models. The models cover over 250 standard and complex structures, such as lymph nodes, bowel loops, and brachial plexus, as well as anatomical landmarks. These structures are tightly aligned with international contouring guidelines provided by RTOG, ESTRO, UK SABR Consortium, and many others.

Brain CT

The Brain CT model covers 28 OAR structures used in brain tumor radiotherapy treatment planning. View official Guidelines

OAR Structures

Brain MR

The Brain MR model* includes 29 OAR structures. The majority of these are based on the EPTN guidelines published in 2018 and 2021. The model supports high resolution T1 sequences from multiple MRI vendors. View official Guidelines

OAR Structures

Head & Neck CT

This complex and high-quality model contains a total of 74 structures, both OARs and Lymph node regions, specific for Head and Neck cancer treatments. The model works with both contrast and non-contrast enhanced scans and handles dental filling artefacts and different anatomies well. View official Guidelines

Breast CT

The breast CT model comprises over 55 ROIs. The breast radiotherapy-specific structures are based on the ESTRO, RTOG, and RADCOMP guidelines. In addition to the standardized structures, ready-made combinations of the target volumes are included. Heart chambers are also provided according to the Milo et al. 2020 guideline.

GDPR & HIPAA Compliant Workflow

Security is built into the software.

All images are pseudo-anonymised and delivered to the MVision AI cloud only to generate the contouring results. Data is uploaded to the cloud through an encrypted connection to be processed by the AI algorithm. Once the organs are auto-segmented, the data is sent back to the clinic via the same encryption/decryption process. Received data is deleted from the cloud server after 24 hours. The whole process including uploading, processing, and receiving results takes only a few minutes, automatically in the background.

MVision AI workflow

How does it work?

CT/MRI scans are sent encrypted and anonymized to the MVision AI cloud with just a click. An AI algorithm draws the 3D models of the organs and returns the data to the clinic.

This happens as an automated background process. Software is HIPAA and GDPR – compliant. Safety by design is a core principle of the software.
