"computed tomography"的定义和意义

What is "computed tomography"?

Computed tomography, commonly known as CT, is a medical imaging technique that uses X-rays and computer processing to create detailed images of the body. It allows healthcare providers to visualize internal structures such as bones, organs, and tissues in great detail, helping in the diagnosis and monitoring of various medical conditions. During a CT scan, the patient lies on a table that moves through a doughnut-shaped machine while X-ray beams rotate around the body. The resulting images provide valuable information about the size, shape, and density of the structures inside the body, helping healthcare professionals to identify abnormalities and plan appropriate treatment.
