The application of dual energy (DE) subtraction techniques to quantitative coronary arteriography (QCA) has the advantage of removing the tissue signal surrounding the vessel profile. We have compared the performance of two geometric QCA algorithms o

Scatter-glare corrections in quantitative dual-energy fluoroscopy

Autor: S Y, Molloi, C A, Mistretta

Publikováno v: Medical physics. 15(3)

Previous attempts to use time subtraction intravenous digital subtraction angiography for ventricular imaging have been hampered by artifacts due to cardiac and respiratory motion. We have previously reported a motion-immune dual-energy technique in

Quantification techniques for dual-energy cardiac imaging

Autor: S Y, Molloi, C A, Mistretta

Publikováno v: Medical physics. 16(2)

We have previously reported a motion immune dual-energy subtraction technique in which x-ray tube voltage and x-ray beam filtration are switched at 30 Hz between 60 kVp (2.0-mm Al filter) and 120 kVp (2.0-mm Al + 2.5-mm Cu filtration). In this paper
