Digital image data acquired during cardiac catheterization will soon be archived on standardized digital storage media. However, with the enormous amount of generated data, considerable time will be wasted at later reviewing or at conferences, or whe

In order to review the morphological criterion for an interventional procedure, diameter stenosis (%DS) of 226 coronary lesions in 200 patients undergoing elective coronary angiography with an option for 'prima vista' angioplasty (pPTCA), was assesse

A system for digital flashing tomosynthesis (DFTS) consists of four electrocardiogram-gated and simultaneously flashed x-ray tubes, a 14" image intensifier, a unit for digital subtraction angiography (DSA), a personal computer-hosted transputer netwo

In conjunction with interventional cardiovascular procedures, eye balling, especially when executed by the coronary angiographer, tends to infer self referral bias due to overestimation of stenosis severity in lesions of 40–60% diameter reduction i

BACKGROUND It is known that first-generation quantitative coronary angiography (QCA) systems overestimate small vessel sizes owing to the point-spread function of the respective X-ray imaging chain. With second-generation systems new algorithms were

Computer-assisted image analysis systems for quantitative coronary angiography [QCA] require added investments in terms of both time for the analyses and money for additional equipment. Their utilization for routine work appears justified only by a c

Tomosynthesis presents a simple procedure for angiography because the recording step requires only one injection of contrast medium. Digital flashing tomosynthesis (DFTS) is based on a new nonlinear reconstruction producing fewer artifacts than conve

Digital Flashing Tomosynthesis (DFTS) represents a technique for three-dimensional (3D) coronary angiography. Four ECG-gated simultaneously flashed X-ray tubes generate a multiperspective digital substraction image as DFTS multiangiogram for 3D recon

To determine whether compensatory enlargement of atherosclerotic coronary arteries occurs and to what degree it affects the angiographic assessment of coronary artery disease, we performed postmortem coronary angiography of 30 human hearts with suspe
