Final answer:
Modern X-ray technology utilizes CT scans to produce detailed cross-sectional and three-dimensional images of the body's internal structures.
Step-by-step explanation:
Modern X-ray technology allows for the creation of images of bones and tissues through computed tomography (CT), also known as computed axial tomography (CAT). Traditional X-rays provide two-dimensional images from a single angle, but CT scans take this further by taking multiple X-ray measurements from different angles. These are processed by computers to construct cross-sectional views or 'slices' of the body. The patient lies on a table that moves through a rotating X-ray tube and detector array. The raw data collected from these 'slices' is then subject to complex computer image processing, which interprets varying degrees of X-ray absorption to produce highly detailed images. Furthermore, multiple slices can be analyzed to yield detailed three-dimensional images of the patient's internal structures.
