Since the early 1960s, selective x-ray coronary angiogra-phy has provided the only means
of visualizing the coronary arterial system in vivo. However, it has several disadvantages …

Methods The cardiovascular system can be imaged with the use of two different computer
tomography (CT) modalities: one employs nonmechanical movement of the x-ray source (ie …

Background A new generation of subsecond multi-slice computed tomography (MSCT)
scanners, which allow complete coronary coverage, are becoming widely available. We …

Background—We investigated the applicability and image quality of contrast-enhanced
coronary artery visualization by multislice spiral CT using retrospective ECG gating. Methods …

A method and system for physiological gating is disclosed. A method and system for
detecting and predictably estimating regular cycles of physiological activity or movements is …

BACKGROUND: Magnetic resonance imaging (MRI) and multislice computed tomography
(MSCT) have emerged as potential noninvasive coronary imaging techniques. The objective …

The concept of risk assessment and reduction, introduced initially by the Framingham Heart
Study and refined in other models, forms the cornerstone of preventive cardiology. Risk …

Respiratory motion may reduce the sensitivity of 18F-FDG PET for the detection of small
pulmonary nodules close to the base of the lungs. This motion also interferes with attempts …

(57) ABSTRACT A method for generating one or more images includes col lecting data
samples representative of a motion of an object, acquiring image data of at least apart of the …
