The primary application is the improved visualization of regions of the heart and circulation opacified by X-ray contrast material during angiographic and angiocardiographic examinati

Although DSA techniques are by no means uniform, imaging rates for those first four anatomic regions are typically one image per second. Generally, a sequence of 10 to 15 short, intense exposures is mad

Quantitative Aspects of Image Intensifier- Television-Based Digital X-Ray Imaging, obtained by such systems, the X-ray video systems also offer the potential for extracting quantitative information from the images. In this chapter we will not deal with quantitative determinations based on distance measurements. Even though the quantitation potential has been under investigation f

For non-cardiac studies, this technique uses X-ray exposures made approximately once per second for a total of 15 to 20 exposures spanning the duration of the arrival and washout

The central questions are: How clinically relevant is this added information? How can measurements be

These systems have in common the acquisition of a two-dimensional projection image in digital format but include a variety of detectors, techniques, and applications. The key attributes of these systems are improvements in detector design and the ability to process the ima
