What is a X-ray CT device?

X-ray CT is a technique for examining the material and structure inside an object by irradiating it with X-rays. In X-ray CT, a cross-sectional image of an object is obtained by irradiating the object with X-rays from all directions at 360 degrees, examining the X-ray dose transmitted through the object and absorbed by the object, and reconstructing the obtained data with a computer. You can get it. Recently, the obtained cross-sectional image is also converted into a three-dimensional structure. In addition to X-ray CT, there is NMR as a technique for investigating the internal structure of an object, but NMR is a technique that uses magnetic fields and radio waves instead of X-rays, and is completely different from X-ray CT.

Application of X-ray CT device

X-ray CT equipment is mainly classified into medical and industrial applications. Medical X-ray CT is used to obtain internal information about the human body and determine the medical condition. There are two types of medical X-ray CT, simple CT and contrast CT using a contrast medium, and either one is selected according to the purpose. In industrial applications, it is mainly used for non-destructive inspection of substances. Examples include shape evaluation and defect investigation of semiconductor packages, internal structure evaluation of tablets, and shape and fiber orientation evaluation of carbon fiber reinforced plastics.
