Medical image processing leads to an improvement in patient care by guiding the surgical gesture. Three-dimensional models of patients that are generated from computed tomographic scans or magnetic resonance imaging allow improved surgical planning and surgical simulation that offers

The purpose of this chapter is to present a survey of recent publications concerning medical image registration techniques. These publications will be classified according to a model based on nine salient criteria, the main dichotomy of which is extrinsic versus intrinsic methods The statistics

This paper surveys the field of Augmented Reality, in which 3-D virtual objects are integrated into a 3-D real environment in real time. It describes the medical, manufacturing, visualization, path planning, entertainment and military applications that have been explored. This paper describes the characteristics of Augmented Reality systems, including a detailed discussion of the tradeoffs between optical and video blending approaches. Registration and sensing errors are two of the biggest problems in building effective Augmented Reality systems, so this paper summarizes current efforts to overcome these problems. Future directions and areas requiring further research are discussed. This survey provides a starting point for anyone interested in researching or using Augmented Reality. 1. Introduction 1.1 Goals This paper surveys the current state-of-the-art in Augmented Reality. It describes work performed at many different sites and explains the issues and problems encountered when ...

augmented reality guidance probe and method

Spine Procedures ” Workshop was held April 17–

for surgeons to visually inspect an area of pathology, their efforts have increasingly been directed towards planning and performing the least invasive procedure. Imaging is being used to guide such operations. One of the least invasive procedures of all is called stereotactic radiosurgery. Stereotactic

Abstract: We describe a radiosurgical system based onanovel medical linear accelerator of particularly light weight, a six degree-of-freedom robotic arm and an on-line x-ray vision system. The system introduces a class of radiosurgical procedures, termed non-stereotactic, or image-guided

imaging for guiding breast surgery. This thesis proposes that a patient-specific biomechanical model, based on preoperative MR images acquired in the prone position, can assist the task of locating a surgical target within a supine patient. The ability of such models to simulate gravity
