Validation of real-time intensity based 2D/3D registration for image guided radiotherapy
No opinion
Patient motion during radiotherapy or intra-fractional motion, is one of the major sources of uncertainty in dose application. 2D/3D registration is an intensity based method used successfully to track tumor motion with the potential to reduce uncertainty. [...]

Gauss-Newton Method for Segmentation assisted Deformable Registration
No opinion
In this work, we try to develop a fast converging method for segmentation assisted deformable registration. The segmentation step consists of a piece-wise constant Mumford-Shah energy model while reg- istration is driven by the sum of squared distances of [...]

Automatic accuracy measurement for multi-modal rigid registration using feature descriptors
No opinion
In radiotherapy (RT) for tumor delineation and diagnostics, complementary information of multi-modal images is used. Using high ionizing radiation, the accuracy of registered volume data is crucial; therefore a reliable and robust evaluation method for [...]
