The Geometric Deformable Model is developed for accurate colon lumen segmentation as part of an automatic Virtual Colonoscopy system. The deformable model refines the lumen surface found by an automatic seed location and thresholding procedure. The challenges to applying the deformable model are described, showing the definition of the stopping function as… (More)

A case is presented that illustrates the use of computerized tomography for the evaluation of an odontoid fracture in a child. Such a "fracture" may actually represent a "synchondrotic slip" of the odontoid and C-2 vertebral body between the neural arches of C-2. Treatment should almost always be conservative. Complete healing of the injury is expected.
