Medical Applications of Chamfer Matching

Most applications of the chamfer matching algorithm have been in the field of radiotherapy, although a few authors have published applications outside this field [18]. In the next sections, first the use of 2D chamfer matching for treatment verification for radiotherapy is described, then the use of 3D
