Registry build 21.09.26

Limbus Contour is software that automatically segments normal tissues on CT or MR images for radiation treatment planning. It uses pretrained machine-learning models and additional processing to generate anatomical contours for trained clinical professionals.

The application imports DICOM image files and exports DICOM RT structure sets. It relies on an external treatment planning system or image viewer for displaying images and editing the generated contours.

Listed Item

Limbus Contour is a stand-alone software medical device. It is a single purposes cross-platform application for automatic contouring (segmentation) of CT/MRI DICOM images via pre-trained and expert curated machine learning models. The software is intended to be used by trained medical professionals to derive contours for input to radiation treatment planning. The Limbus Contour software segments normal tissues using machine learning models and further post-processing on machine learning model prediction outputs. Limbus Contour does not display or store DICOM images and relies on existing radiotherapy treatment planning systems (TPS) and DICOM image viewers for display and modification of generated segmentations. Limbus Contour interfaces with the user’s operating system file system (importing DICOM image.dcm files and exporting segmented DICOM RT-Structure Set.dcm files).

Scope and Limits

The software supports localization and definition of anatomical structures and transfer of contours into radiotherapy planning workflows. It is not intended to automatically contour tumors or clinical target volumes and does not support digital mammography. The application itself does not provide image fusion or three-dimensional rendering.
