CT scan is also known as a CAT scan and is extensively used for detection of diverse conditions and disorders of the human body. Computerized Tomography is a highly evolved technology that leverages X-ray and digital geometry techniques to explore human organs, bones, nerves, and soft tissues to name a few.
CT scan BHU machine appears as a huge donut-shaped ring and the patient has to lie down on a sliding bed that is able to move in and out of the ring-like structure. The CT scan machine has been provided with X-ray detectors and is connected to a computer that is fed with the data obtained by the machine.
You can get the clear picture of tissues in varying densities and colors in the form of multiple cross-sectional images. Some of the latest CT scanners are designed to deliver three-dimensional images for better investigation.
Uses of CT scan examination
CT Scan is commonly performed to detect anomalies of the brain and spinal cord. It presents far better images of soft tissues than a traditional X-ray examination although the basic principle is almost the same. One can view vital organs including brain, heart, spleen, and other important parts of the body including coronary blood vessels, lungs and so forth.
