A CT (computed tomography) scanner consists of several key components:

X-ray Tube: This emits X-rays, which penetrate the body and are detected by sensors on the opposite side of the patient.

Detectors: These sensors measure the intensity of X-rays that pass through the body from various angles. The data collected by detectors are used to create cross-sectional images.

Gantry: The gantry houses the X-ray tube and detectors. It rotates around the patient during the scanning process.

Patient Table: The table on which the patient lies during the scan. It can move into and out of the gantry to position the patient correctly for imaging.

Computer System: A powerful computer processes the data collected by the detectors and reconstructs it into detailed cross-sectional images of the body.

Control Console: This is where the radiologic technologist operates the CT scanner, adjusting settings and monitoring the scan in progress.

These components work together to produce detailed images of the inside of the body, helping physicians diagnose and treat various medical conditions.
