TU‐G‐WAB‐01: Advanced Applications in Deformable Registration

The field of deformable image registration has seen many technical advances over the past decade, with increases in accuracy, the speed of the algorithms, and the flexibility of the algorithm to handle complex, multi‐modality images. These technical advances have enabled further advances in the applications of deformable image registration. This symposium will cover exciting new applications of deformable registration, ranging from population models, to image‐guided treatments outside of external beam radiotherapy, to image validation through correlative pathology. Deformable registration is generally thought of to be between two images of the same patient, for purposes of aiding the patient's radiotherapy treatment. However, novel applications are using deformable registration in applications outside of this space. Examples will include the investigation of population based information, such as the determination of a risk‐based CTV. The use of deformable registration for image validation through correlative pathology will be described including challenges and results of early studies. Exciting advances of hybrid registration technology for robust and efficient deformable registration for image‐guided surgery will also be illustrated. Learning Objectives: 1. Describe the use of deformable registration for advanced image‐guided treatments. 2. Understand the application of deformable registration for population‐based models. 3. Describe the use of deformable registration for image validation in correlative pathology.
