Abstract
In an image guidance method, a stream of cone-beam computed tomography (CBCT) images of an anatomical organ is acquired using a CBCT imaging device (). For each CBCT image (), the surface of the organ in the CBCT image is segmented to generate a segmented surface () of the anatomical organ in the CBCT image. Occluded shape reconstruction () using a statistical shape prior () may be used to reconstruct a missing or occluded surface portion. A pre-operative medical image () of the anatomical organ and the CBCT image are spatially registered by warping one of the images to the other of the images using point set registration of a segmented surface () of the organ in the preoperative medical image and the segmented surface of the organ in the CBCT image. A fused image () is displayed that combines the warped image and the other image.
