1.辐射断层扫描的原理在辐射断层扫描中,数据探测是比较简单的,它借助于环绕身体轴向旋转的多普勒探测器可以得到一个通过身体断面的横截面图象,同时贮入连接在计算机上的磁性存储器内。断面越多,也就是断面间的角度越小,重建的图象就越精确。展示的横断面厚度取决于所选择的准直器的焦点,为了保持 1. The principle of radiation tomography In radiation tomography, data detection is relatively simple, which uses the body around the body around the axis of rotation Doppler detector can be obtained through a cross-sectional image of the body section, while stored in the connection Inside the computer’s magnetic memory. The more sections, that is, the smaller the angle between the sections, the more accurate the reconstructed image will be. The thickness of the cross-section shown depends on the focal point of the selected collimator, in order to maintain
