Abstract

Following a brief introduction of radiotherapy historical development, the presentation dives into the heart of treatment planning and optimization. With additional degrees of freedom, the optimization problem becomes increasingly complicated with increasing dosimetric benefits. A particularly important application is non coplanar radiotherapy. Benefit from solving a related optimization problem, image reconstruction can be accelerated for image guided radiotherapy. To more effectively use the images, automated segmentation has been developed. In addition to anatomical targeting, tumor radiobiology, as revealed by functional images, adds another dimension to radiotherapy. The combination of image acquisition, segmentation, biological targeting, and optimization leads to the future of personalized precision radiotherapy.
