In the context of neonatal non invasive monitoring, this paper proposes the estimation and characterization of the motion of premature newborns from long duration video recordings.A set of 13 videos from 9 different patients, corresponding to 190 hours of recordings, have been studied. An algorithm based on the analysis of changes in the image border has been used to remove intervals artifacted by...
Radiotherapy (RT), alone or combined with surgery and/or chemotherapy is given to almost all head and neck cancer (HNC). The goal of RT is to increase as much as possible the dose in the tumor to cure the patient, while limiting the dose in the organs at risk, mainly the parotids gland to limit the xerostomia. HNC RT appears particularly challenging due to the complexity of the shape of the anatomical...
Cervical cancer is one of the most common cancers to affect women worldwide. Despite the efficiency of radiotherapy treatment, some patients present post-treatment tumor recurrence, which increases the risk of death. Several studies suggest that tumor characteristics visible with PET imaging before and during the treatment could be used to predict post-treatment recurrence. We evaluate the contribution...
Image registration appears to be an essential tool in a wide range of biomedical applications. We are interested in performing voxel-wise population analysis aimed at explaining sideways effects of dose irradiation across a population treated for prostate cancer. To this end, a perfect registration of pelvic computed tomography (CT) scans is required allowing a reliable mapping of dose distributions...
