This paper presents a semiautomatic method for the registration of images acquired during surgery with a tracked laser range scanner (LRS). This method, which relies on the registration of vessels that can be visualized in the pre- and the post-resection images, is a component of a larger system designed to compute brain shift that occurs during tumor resection cases. Because very large differences...
This paper reports a vessel structure based non-rigid registration method for cortical surface registration and deformation tracking using a laser-range scanner(LRS). The LRS contains both geometric and texture information of the brain surface, i.e. the unit produces a three-dimensional (3-D) textured point cloud. Unlike our previous registration work, in this paper we investigate using vessel structures...
