Abstract: In thoracic radiotherapy, some organs should be considered with care and protected from undesirable radiation. Among these organs, the heart is one of the most critical to protect. Its segmentation from routine CT scans provides valuable information to assess its position and shape. In this paper, we present a novel variational segmentation method for extracting the heart on non-contrast CT images. To handle the low image contrast around the cardiac borders, we propose to integrate shape constraints using Legendre moments and adding an energy term in the functional to be optimized. Results for whole heart segmentation in non-contrast CT images are presented and comparisons are performed with manual segmentations.
