Helical/spiral computed body tomography
Clinical Radiology, 1997 Summary Helical CT has profound implications for routine imaging in the chest and abdomen as well for specialized imaging of hollow organs and blood vessels. The ability to image the chest or abdomen in a single breath and to review overlapping images retrospectively has improved our ability to detect and measure the attenuation of small lesions ...

Computer Models of Spiral Structure [PDF]
Symposium - International Astronomical Union, 1970 A computer model for isolated disks of stars is used to study the self-consistent motion of large numbers of point masses as they move in the plane of the galactic disk. The Langley Research Center's CDC 6600 computers are used to integrate the equations of motion for systems containing from 50000 to 200000 stars.

Dynamic Enhanced Computed Tomographic Findings of a Perirenal Capillary Hemangioma
대한영상의학회지, 2016 Hemangiomas are benign mesenchymal neoplasms that rarely occur in the kidney and perirenal space. Perirenal hemangiomas can mimic the appearance of exophytic renal cell carcinoma or various retroperitoneal tumors. We report a case of perirenal hemangioma

Spiral computed tomography of pulmonary embolism [PDF]
European Respiratory Journal, 2002 Within the last several years, spiral computed tomography angiography (SCTA) of the pulmonary arteries has emerged as a noninvasive angiographic modality for the evaluation of patients with suspected pulmonary embolism (PE). SCTA is based on continuous computed tomography (CT) data acquisition during patient transport through the rotating X‐ray tube ...

Spiral Computed Tomography for Acute Pulmonary Embolism [PDF]
Circulation, 2004 There is still considerable debate about the optimal diagnostic imaging modality for acute pulmonary embolism. If imaging is deemed necessary from an initial clinical evaluation such as d -dimer testing, options include nuclear medicine scanning, catheter pulmonary angiography, and spiral CT.
