Tomography is a technique used to create detailed images of the inside of objects, especially in medicine. It works by taking multiple X-ray images from different angles and then using a computer to combine them into a single, clear picture. This allows doctors to see structures like bones and organs without needing to perform surgery. One common type of tomography is CT scans, which stands for computed tomography. These scans are widely used in hospitals to diagnose various conditions, such as tumors or fractures. By providing a cross-sectional view of the body, tomography helps healthcare professionals make better decisions about treatment.
