Technique: The basic computed tomographic image of the heart consists of a transverse tomographic section constructed by computer from approximately 90,000 X-ray attenuation measurements. The X-ray pulses are produced by an X-ray tube that is supported by a circular gantry that also carries a detector array.

Computed tomography colonography
Hospital Medicine, 2001Computed tomography colonography (virtual colonoscopy) is an exciting technique that continues to evolve but promises to be a valuable tool for diagnosis of and screening for colorectal neoplasia.

Quantitative Computed Tomography
Seminars in Musculoskeletal Radiology, 2002Quantitative computed tomography (QCT) is an established technique for measuring bone mineral density (BMD) in the axial spine and peripheral skeleton (forearm, tibia). QCT can determine in three dimensions the true volumetric density (mg/cm 3) of trabecular or cortical bone at any skeletal site.

Radiologic Clinics of North America, 1976
Only the surface of the diagnostic possibilities inherent in CT imaging has been scratched. Solic organ pathology is readily visible in most instances by computed tomography. With further extension of present knowledge and development of newer contrast agents, the ability of computed body tomography to image a wide range of diseases appears almost ...

Clinical Techniques in Small Animal Practice, 2006
Chronic nasal disease is often a challenge to diagnose. Computed tomography greatly enhances the ability to diagnose chronic nasal disease in dogs and cats. Nasal computed tomography provides detailed information regarding the extent of disease, accurate discrimination of neoplastic versus nonneoplastic diseases, and identification of areas of the nose

The development in helical computed tomography (CT) from single-detector to multidetector equipment has overcome peristaltic intestinal artefacts, allowing optimal bowel visualisation and contrast enhancement (CE). As a result, this permits a finer representation and a more accurate evaluation of the bowel and mesentery.

Computed Tomography Enterography
Radiologic Clinics of North America, 2018Computed tomography (CT) enterography is a noninvasive imaging modality with superb spatial and temporal resolution, specifically tailored to evaluate the small bowel. It has several advantages over other radiologic and optical imaging modalities, all of which serve as complementary investigations to one another.

JAMA: The Journal of the American Medical Association, 1975
A remarkable and fundamentally new radiological technique has recently become available and has been in clinical use in North America since July 1973. In this British invention, the originality of the method lies essentially in the use of a small computer for processing of x-ray photon attenuation data, as measured by sodium iodide crystal detectors ...

Current Opinion in Cardiology, 1991
Ultrafast computed tomography is a developing cardiac imaging modality that can provide high temporal and spatial resolution images of the beating heart in the outpatient setting. The three-dimensional registration of these images has facilitated numerous studies showing this device to be capable of quantitating cardiac anatomy, cardiac function, and ...

Stereotaxic computed tomography
American Journal of Roentgenology, 1976A method for stereotaxic computed tomography is described. A head fixation system has been devised enabling the exact transfer of information fromthe diagnostic coordinate system of the scanner to other therapeutic or diagnostic coordinate systems.
