THREE-DIMENSIONAL INTRAVASCULAR IMAGING WITH ULTRASOUND

拟议工作的目标是调查的可行性 在血管内进行三维超声成像 系统 本研究的目的是提供一种指导手段， 血管内治疗：特别是使用准分子激光的血管成形术 和光纤传输系统。 该项目将重点关注 开发了一种成像方法，该方法可以提供 激光导管正前方的体积。 这种类型的图像， 实时获得并显示，将为外科医生提供有价值的 在激光血管成形术过程中提供指导和协助。 超声波 在这个项目的过程中开发的成像技术将形成 激光血管成形术引导仪器的基础 程序.

The goal of the proposed work is to investigate the feasibility of performing three-dimensional ultrasonic imaging form within the vascular system. The purpose for this research is to provide a means of guiding intravascular therapies: specifically, angioplasty using excimer lasers and a fiber optic delivery system. This project will focus upon development of an imaging method which can provide multi-planar images of the volume directly ahead of the laser catheter. Images of this type, obtained and displayed in real-time, will provide the surgeon with valuable guidance and assist during the course of laser angioplasty. The ultrasonic imaging techniques developed during the course of this project will form the basis for an instrument dedicated to guidance of laser angioplasty procedures.
