Biplane digital subtraction angiography
Computerized Radiology, 1986Biplane digital subtraction angiography was performed by placing a rapid switch between the anteroposterior and lateral T.V. cameras and the A-D converter. Alternate exposures from two X-ray tubes were employed. Excellent anteroposterior and lateral DSA was obtained especially for the brain and neck.

Cardiac applications of digital subtraction angiography [PDF]
The International Journal of Cardiac Imaging, 1985 Recent developments in digital computer technology have enabled direct digital acquisition of radiographic images at spatial and temporal resolutions similar to that of cineradiography. Initially intended as a means of performing peripheral angiography, digital subtraction angiography has been increasingly applied to cardiac catheterization procedures.

Digital Subtraction Angiography
2019Despite the continued refinement of vascular ultrasound and noninvasive cross-sectional imaging studies (computed tomography angiography [CTA] and magnetic resonance angiography [MRA]) in the diagnosis of vascular pathologies, digital subtraction angiography (DSA) remains the “workhorse” imaging modality for the diagnosis and management of peripheral ...

OBJECT The purpose of aneurysm surgery is complete aneurysm obliteration while sparing associated arteries. Indocyanine green (ICG) videoangiography is a new technique that allows for real-time evaluation of blood flow in the aneurysm and vessels.

Pediatric digital subtraction angiography.
Radiology, 1984Experience with intravenous digital subtraction angiography (DSA) in infants and children is limited, although its relative ease of performance, low complication rate, and diagnostic accuracy indicate great potential. We performed 87 DSA examinations (74 patients) and obtained sufficient detail to facilitate diagnosis in most cases.

Digital subtraction angiography apparatus.
Radiology, 1985An inexpensive digital subtraction angiography (DSA) apparatus that can perform live subtraction, processed subtraction, and road mapping is described. The apparatus can be used in any standard x-ray room with fluoroscopic capability, with a simple connection to the existing TV chain. It is especially useful in therapeutic neuroangiography.

Flexible Mask Subtraction For Digital Angiography
SPIE Proceedings, 1988A flexible-mask algorithm that effectively provides correction for motion artifacts and gray-level variations in digital subtraction angiography (DSA) images is presented. The algorithm makes use of a flexible local registration of the mask with the live image to minimize the main distortions caused by the complex motion of the heart, namely spatial ...

Quantification of arterial flow using digital subtraction angiography.
Medical Physics (Lancaster), 2012PURPOSE In this paper, a method for the estimation of arterial hemodynamic flow from x-ray video densitometry data is proposed and validated using an in vitro setup.
