X-ray Computed Tomography, often called CT scan, is a medical imaging technique that creates detailed pictures of the inside of the body. It uses X-rays and a computer to produce cross-sectional images, allowing doctors to see organs, bones, and tissues in great detail. This helps in diagnosing various conditions, from fractures to tumors. During a CT scan, the patient lies on a table that moves through a large, doughnut-shaped machine. As the machine rotates, it takes multiple X-ray images from different angles. These images are then combined by a computer to create a 3D view, making it easier for healthcare professionals to assess and plan treatment.
