What is a computerized axial tomography used for?
A procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional (3-D) views of tissues and organs.
Which imaging is used for computerized axial tomography?
What is a Computerized Axial Tomography (CT Scan)? Computerized Axial Tomography (CT) scan use X-ray beams to take a look at cross-sections of the body providing 3D technology in less than a minute. During a CT scan, the X-rays and detectors rotate around the body while the table slides through the tubular machine.
What are the components of CT image?
Production of Images. CT scanners are composed of three important elements: an X-ray tube, a gantry with a ring of X-ray sensitive detectors, and a computer. In this method, images are created using the same physics principles as in conventional radiography.
How are CT images constructed?
CT images are two-dimensional pictures that represent three-dimensional physical objects. The images are made by converting electrical energy (moving electrons) into X-ray photons, passing the photons through an object, and then converting the measured photons back into electrons.
What are the different types of CT scans?
CT Angiography. CT Scan Arthrography. CT Scan Bones. CT Scan Brain/ CT Scan Head.
What is the principle of CT?
CT uses ionizing radiation, or x-rays, coupled with an electronic detector array to record a pattern of densities and create an image of a “slice” or “cut” of tissue. The x-ray beam rotates around the object within the scanner such that multiple x-ray projections pass through the object (Fig 1).
What is CT scan PPT?
1. Basics of CT Scan. 2. CT (CAT) scanning —is a noninvasive medical test that helps physicians diagnose and treat medical conditions. – combines special x-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body.
What are CT techniques?
A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan images provide more-detailed information than plain X-rays do.
