Surface Registration for Use in Interactive Image-Guided Liver Surgery
OBJECTIVE Liver surgery is difficult because of limited external landmarks, significant vascularity, and inexact definition of intra-hepatic anatomy. Intra-operative ultrasound (IOUS) has been widely used in an attempt to overcome these difficulties, but is limited by its two-dimensional nature, inter-user variability, and image obliteration with ablative or resectional techniques. Because the ...
متن کاملFlow Surface Probes for Vector Field Visualization
We present a technique called ow surface probes for interactive visualization of 3D steady vector elds. The user places in the ow eld an arbitrarily-shaped seed surface, which is then deformed over time by the local or global 3D vector eld, producing an animation sequence. This sequence and individual frames are used to probe the behavior of the ow eld.

متن کاملDiodes Laser in Ent Surgery
LASER in the otology field was used to perform tympanotomy and for the placement of ventilation tubes, vaporization of horny pearls and adhesion in the eardrum, remobilisations and ossicular modelings, “spot-welding”; in this field the most argued area of applicability of LASER is the surgery of the otosclerosis. The otosclerosis treatment with surgical LASER started with Perkins and Di Bartolo...
متن کاملSurface reconstruction of detect contours for medical image registration purpose
Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...
