颈动脉三维超声成像系统的建立
Establishment ofA 3-D Ultrasonic Imaging System
摘要
Abstract
With the development of economy,the incidence of ischemic stroke is increasing.The main pathological basis of ischemic stroke is atherosclerosis.Ultrasonic imaging is widely used in the diagnosis of carotid atherosclero-sis worldwide.However,traditional ultrasonic image belongs to 2-D cross-sectional image,which lacks intuition.This paper works on a slipway system based on serial communication,a video acquisition system realized by video capture card and GPU-based 3-D reconstruction through volume rendering of 3-D texture mapping.The motor,driven by single-chip-computer,is used to control slipway-probe mechanical system.The capture card collects a real-time changing video of the ultrasonic machine as the start-stop signals is transmitted to the computer soft-ware through the serial port communication to achieve overall synchronization.A set of intermittent and spatially correlated pictures,which is extracted frame by frame frome the captured video,is used for the reconstruction by volume rendering based on texture mapping.Through establishing a 3-D ultrasonic imaging machine for carotid ar-tery,the feasibility of the system is verified with a large number of experimental tests.关键词
