Prostate brachytherapy

MRI /US data fusion for prostate brachytherapy

This project aimed at improving echographic data interpretation during prostate brachytherapy. Pre-operative MRI data are automatically registered to intra-operative trans-rectal ultrasound images using a 3D/3D elastic surface matching. For each echographic image, the corresponding MRI data are computed and a composite image is produced. The user can interact with the image. This facilitates USimage segmentation (especially close to the prostate extremities) from which dosimetric planning is performed.
