随着现代工程技术尤其是电子技术、微型计算机技术应用于医学领域,出现了不少智能医学仪器。所谓的“智能医学仪器”实际上就是指带微机的医学仪器。与以往的仪器不同,它本身具有一定的逻辑判断能力,为医务工作者和医学科研人员提供了有力的诊断和治疗手段。下面介绍几种智能医学仪器足以说明这一点。 1.X线断层扫描装置(简称CT):由X线管和X线探测器群所组成的测量扫描系统获取大量的测量值,并将它送入电子计算机进行处理,从而求出相应衰减系数的数字矩阵并重建图象。即能无损伤地显示人体横断面图象。 2.核磁共振CT扫描装置;施加于人体的高频磁场,引起核磁共振。由接收探头检
With the modern engineering technology, especially electronic technology, micro-computer technology used in medicine, there have been many smart medical instruments. The so-called “smart medical instrument” actually means a medical instrument with a microcomputer. Different from the previous instruments, it has certain logic judgment ability itself, which provides powerful diagnoses and treatments for medical workers and medical researchers. The following describes several smart medical devices sufficient to illustrate this point. 1. X-ray tomography device (referred to as CT): The X-ray tube and the X-ray detector cluster consisting of measurement and scanning system to obtain a large number of measurements and send it to the computer for processing, so as to find the corresponding attenuation coefficient Digital matrix and reconstruct the image. That is able to show human body cross-sectional images without damage. 2 nuclear magnetic resonance CT scanning device; applied to the human body high-frequency magnetic field, causing nuclear magnetic resonance. Detected by the receiving probe
