A CT scan, or computed tomography scan, is a medical imaging technique that uses X-ray technology combined with computer processing to create detailed cross-sectional images (slices) of the body’s internal structures, including bones, blood vessels, muscles, and soft tissues

. Unlike a standard X-ray that produces a flat 2D image, a CT scan takes multiple X-ray images from different angles as the machine rotates around the patient, and then a computer reconstructs these into detailed 2D or 3D images

. CT scans are used to diagnose a wide range of conditions such as bone fractures, tumors, infections, blood clots, internal injuries, and diseases like cancer and heart disease. They also help guide medical procedures like biopsies and surgeries, and monitor the effectiveness of treatments

. The procedure is typically quick, painless, and minimally invasive, with the patient lying on a table that moves through a doughnut-shaped scanner while images are taken

. In summary, a CT scan provides a more detailed and precise view inside the body than regular X-rays, making it a valuable tool in medical diagnosis and treatment planning
