Learning Embeddings for Atlas Propagation (LEAP)
IXICO's patented LEAP (Learning Embeddings for Atlas Propagation) technology uses AI to provide a customized anatomical atlas for a given MRI image, leveraging IXICO’s large reference database to obtain an optimized segmentation for every given case. LEAP allows us to measure brain volume both cross-sectionally and longitudinally. This provides the following measures:
- Global – making measurements on the whole brain
- Regional – measuring specific local brain regions
LEAP algorithm has been applied to thousands of datasets and provides accurate delineation of key brain structures, while quantifying the volume of up to 137 structures in a single workflow. Using multi-atlas propagation, a flexible and robust method for image segmentation, LEAP is optimized and validated for therapeutic area and region specific segmentations.
In addition to powering our volumetric MRI solutions, LEAP can be deployed in conjunction with other methods such as dMRI, fMRI and PET, enabling the superior accuracy, rigor and efficiency inherent in LEAP algorithms to enhance performances of the paired analyses.
