computed tomography (CT) magnetic resonance imaging (MRI) CT angiography uses a CT scanner to produce detailed images of both blood vessels and tissues in various parts of the body. Relative position of the x-ray tube, patient, and detectors in a fourth generation CT unit. Cross-sections are reconstructed from measurements of attenuation coefficients of x-ray beams in the volume of the object studied. The origin of the word \"tomography\" is from the Greek word \"tomos\" meaning \"slice\" or \"section\" and \"graphe\" meaning \"drawing.\" A CT imaging system produces cross-sectional images or \"slices\" of anatomy, li… Computed tomography: An x-ray procedure that uses the help of a computer to produce a detailed picture of a cross section of the body. The word tomography is derived from Ancient Greek τόμος tomos, "slice, section" and γράφω graphō, "to … Definition of Computed Tomography: A scanning procedure using X-rays and a computer to detect abnormalities of the body's organs. CT angiography is a type of medical test that combines a CT scan with an injection of a special dye to produce pictures of blood vessels and tissues in a part of your body. Word of the day griff https://medical-dictionary.thefreedictionary.com/Computed+tomography. The value in the middle is used as the threshold (ISO 50 method) to set points on the surface. computed tomography. Imaging anatomic information from a cross-sectional plane of the body, each image generated by a computer synthesis of x-ray transmission data obtained in many different directions in a given plane. A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to your heart. Login The method is used in radiology, archaeology, biology, atmospheric science, geophysics, oceanography, plasma physics, materials science, astrophysics, quantum information, and other areas of science. Among the r computed tomography definition: noun Abbr. A computerized tomography (CT) coronary angiogram is an imaging test that looks at the arteries that supply blood to your heart. To determine by mathematics, especially by numerical methods: computed the tax due. It might be used to diagnose the cause of chest pain or other symptoms.A CT coronary angiogram relies on a powerful X-ray machine to produce images of your heart and its blood vessels. Purpose Computed tomography (CT) is an x-ray imaging procedure used for a variety of clinical applications. What is Computed Tomography, Angiography? Please tell us where you read or heard it (including the quote, if possible). Tomography definition is - a method of producing a three-dimensional image of the internal structures of a solid object (such as the human body or the earth) by the observation and recording of the differences in the effects on the passage of waves of energy impinging on those structures. Figure 2: Cross-sectional Image of AbdomenAlthough also based on the variable absorption of x rays by different tissues, computed tomography (CT) imaging, also known as \"CAT scanning\" (Computerized Axial Tomography), provides a different form of imaging known as cross-sectional imaging. Computed Tomography, Renal Synonym/acronym: Computed axial tomography (CAT), computed transaxial tomography (CTT), kidney CT, helical/spiral CT. Common use To visualize and assess the kidney and surrounding structures to assist in diagnosing cancer, tumor, infection, and congenital anomalies. Computed tomography, more commonly known as a CT or CAT scan, is a diagnostic medical test that, like traditional x-rays, produces multiple images or pictures of the inside of the body. The term tomography comes from the Greek words tomos (a cut, a slice, or a section) and graphein (to write or record). Computed Tomography (CT Scan) Definition Computed tomography, commonly called a CT scan, creates multiple cross-section x-ray images to view structures inside the body, especially the bones. X rays are aimed at slices of the body (by rotating equipment) and results are assembled with a computer to give a three-dimensional picture of a structure. These tests are noninvasive and don't require recovery time. imaging anatomic information from a cross-sectional plane of the body, each image generated by a computer synthesis of x-ray transmission data obtained in many different directions in a given plane. To use a computer. Computed tomography. Meaning of Computed Tomography, Angiography as a finance term. It becomes invasive when a contrast medium is used. To measure features, it is necessary to give the object a surface. v.intr. Computed tomography (CT) has had a profound effect on the practice of medicine. CT stands for computed tomography. Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. A computerized tomography scan (CT or CAT scan) uses computers and rotating X-ray machines to create cross-sectional images of the body. A CT scan or computed tomography scan (formerly known as a computed axial tomography or CAT scan) is a medical imaging technique that uses computer-processed combinations of multiple X-ray measurements taken from different angles to produce tomographic (cross-sectional) images (virtual "slices") of a body, allowing the user to see inside the body without cutting. A procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. To summarize, Computed Tomography (CT) is a medical imaging procedure that produces cross-sectional images of the anatomy with the use of radiation. computed tomography (CT) (computerized axial tomography (CAT)) a radiologic imaging modality that uses computer processing to generate an image (CAT scan) of the tissue density in a “slice” as thin as 1 to 10 mm in thickness through the patient's body. What does Computed Tomography, Angiography mean … The term “ computed tomography ”, or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body.
