Tungsten Alloy Radiation Detector in CAT Scanner

A computed tomography (CT) or computerized axial tomography (CAT) scanner is a medical imaging tool that provides clear pictures of the internal structures of the body. Utilizing a beam of x rays and a tungsten alloy radiation detector, it supplies data to a computer, which then constructs a three-dimensional image.

A wide variety of materials, such as tungsten alloy, glass and plastic, are used to construct the components of a CAT scanner. Some of the more specialized compounds can be found in the patient couch, detector array, and the x-ray tube. CAT scanners use X-ray technology to create three-dimensional images of the body's internal structures. Images are obtained by rotating the X-ray generator and tungsten alloy radiation detectors around the patient. This information is fed into a computer, which reconstructs images of the body structures within its plane of focus.

The tungsten alloy radiation detector array of more modern scanners uses tungsten alloy plates, a ceramic substrate, and xenon gas. Tungsten alloy is also used to make the cathode and electron beam target of the X-ray tube. Other materials found in the tube are glass, copper, and tungsten alloy. Throughout many parts of the CAT scanner system, lead can be found, which reduces the amount of excess radiation.
