Neurosurgeons have long used various image-guided systems, such as fluoroscopy, ultrasound, and threedimensional (3-D) stereotaxy in an attempt to more accurately localize intracranial targets (34). The development of advanced neuroimaging techniques over the years has provided the neurosurgeon with increasingly more accurate and precise tools to aid in the microsurgical treatment of intracrani...

This work presents the implementation and comparison of three different techniques of three-dimensional computer vision as follows: • Stereo vision correlation between two 2D images • Sensorial fusion use of different sensors: camera 2D + ultrasound sensor (1D); • Structured light The computer vision techniques herein presented took into consideration the following characteristics: • Computatio...

On account of the advanced technology in recent years, the increasing demand for an effective medical imaging system has addressed its significance in diagnosis especially in the development of threedimensional medical image reconstruction. Of the various software that have been investigated, none of them show efficiency in terms of cost and computational performance. Owing to this fact, a meth...

This paper presents the implementation and validation of a new 3D deformable model method, based on the Mumford-Shah functional for segmentation of threedimensional real-time ultrasound. An experiment on 10 patients with primary hypertension was carried out to compare three segmentation methods for quantification of right and left ventricular ejection fraction: (1) manual tracing by an expert c...
