Faster, guideline-compliant and consistent contours for high-precision radiotherapy.
Guideline-Based Auto-Contouring. AI-Powered Precision
Contour+ is an AI-powered auto-segmentation software that delivers fast and precise automatic delineation of organs-at-risk and lymph node areas. By adhering to industry best practices, Contour+ ensures standardized and consistent contours, resulting in safe and accurate treatment plans delivered with exceptional efficiency.
With Contour+, all users across different clinics begin with the same guideline-based foundation, which facilitates easier inter-clinic collaboration and streamlines research processes.
Contour+
Features and Benefits
Secure and compliant
Contour+ meets GDPR & HIPAA standards
Contour+ is GDPR & HIPAA compliant, ensuring that your clinic maintains the highest standards of data protection and patient privacy. All images are pseudo-anonymized 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 regions of interest (ROIs) are auto-segmented, they are sent back to the clinic via the same encryption/decryption process. Received data is deleted from the cloud server within 24 hours. The entire process, including uploading, processing, and receiving results, takes only a few minutes and happens automatically in the background. This efficiency enables clinicians to make timely, informed decisions, enhancing the overall treatment workflow.
Data Controller:
The clinic is designated as the data controller, retaining full control over patient data while ensuring compliance with privacy regulations.
Data Processor:
MVision AI acts as the data processor, adhering to a comprehensive data processing agreement that guarantees all data handling is secure and compliant with industry standards.
Structure Library
Contour+ encompasses all major anatomical sites and treatment planning structures with state-of-the-art 3D AI models. The models cover 300+ structures, such as head and neck, breast, mediastinal and pelvic lymph nodes or effort intensive OARs like bowel loops, cauda equina and brachial plexus.
These structures are tightly aligned with international contouring guidelines provided by RTOG, ESTRO, UK SABR Consortium, and many others.
The Brain CT model covers 28 OAR structures used in brain tumor radiotherapy treatment planning.
