X线电子计算机体层扫描摄影术(简称CT扫描)——一个多么生疏的名字。当病人预约了这些检查时,你可以按如下的准备向病人解释,以减轻他的顾虑。一、什么是X线电子计算机体层扫描摄影术? CT扫描就是人体某部横削面在不同角度下用狭条的X射线束进行检查。这种射线束,当它与闪烁质点探测器和计算机装置结合用时,能产生出病人脑、肝,肺或其他部位的界限,灰色的合乎比例的图像。CT扫描装置,1972年开始在英国应用,当时他们仅用来检查头颅。从1976年被允许应用到身体的其他部份。
X-ray computed tomography (referred to as CT scan) - a strange name. When the patient has made an appointment for these tests, you can explain to the patient as follows to relieve his concerns. First, what is the X-ray computed tomography? CT scan is a cross-section of the human body at different angles with a narrow X-ray beam to check. This beam of rays, when used in conjunction with a scintillation detector and a computer device, produces a gray, scaled-down image of the brain, liver, lungs or other parts of the patient. CT scanning devices, which began to be used in the UK in 1972, were only used to examine the skull. From 1976 was allowed to apply to other parts of the body.
