直接Ｘ线数字化摄影成像按方式可分为两种 :即线成像与面成像。1 Ｘ线扫描成像原理与应用线扫描是由多个独立的探测单元组成的一维阵列式探测器。探测单元的数目决定该探测器的空间分辨率。该探测器中某一探测单元在某一时刻接收到的Ｘ线光子转换成的电信号代表该探测单元所在
Direct X-ray digital photography imaging can be divided into two ways: the line imaging and surface imaging. 1 X-ray scanning imaging principle and application Line scanning is a one-dimensional array detector composed of multiple independent detection units. The number of detection units determines the spatial resolution of the detector. An electrical signal converted from X-ray photons received by a detecting unit in the detector at a certain moment represents the position of the detecting unit
