摘要
感应式磁声医用成像技术是近两年有关学者提出的一种新的医学成像技术,它在保留传统超声成像优势的前提下,采用脉冲磁场对人体组织激发超声波的新方法,用以弥补传统超声成像的缺陷,提高时患者病情的诊断效果。它是一种具有应用前景并值得研究和探索的成像方法。本文在介绍它的工作原理的基础上,对其实验系统的设计方案进行了研究。
Magnetoacoustic tomography with magnetic induction is a new technology for the medicine imaging, and it was presented recently. The new technology uses pulsed magnetic field to stimulate human body for inducting ultrasonic wave. The technology can remedy the defects of the traditional ultrasonic imaging, and improve the diagnosing quality for patient＇ s condition. It possesses good application prospects, and is worth research. This paper introduces the principle of the imaging method at first, then describes the design scheme of the experiment system.
