A Computer Simulated Biopsy Marking System for Gastroscopy
Bioinformatics and Biomedical Engineering（2010）
Abstract
In this paper, we propose a computer simulated biopsy marking (CSBM) system for gastroscopy physicians. The purpose of the study is to solve two problems: how to mark suspicious areas for follow-ups without hurting stomach, and how to cut down time spent on gastroscopy. By constructing a three-dimensional (3D) virtual stomach model and using a tracking device, the position of gastroscope is shown in multi-view: in triplanar views, in global stomach model views, and in virtual gastroscopy view. In this way, physicians are guided to overcome disorientation so that the time spent on gastroscopy is cut down. By using a tracking device, the positions of suspicious areas are marked virtually in the 3D virtual stomach model. In this way, it will not hurt patients' stomach.
