Image Processors for Digital Angiography Algorithms and Architectures,linical and research work. The clinical advantages offered by this approach have been discussed in several reports.. The primary application is the improved visualization of regions of the heart and circulation opacified by X-ray contrast material during angiographic and angiocardiographic examinatiInoperable 发表于 2025-3-25 09:45:18
Temporal Integration Processing Techniques,tudy the intracranial, extracranial, peripheral, and abdominal vessels, and the cardiac chambers. 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 madfacetious 发表于 2025-3-25 15:08:21

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克制 发表于 2025-3-26 00:00:31
Recursive Filtering Techniques Applied to Digital Subtraction Angiography,valuation of head, neck, and abdominal arteries. Mask-mode image subtraction has been the most widespread DSA technique.. 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 washoutApoptosis 发表于 2025-3-26 00:32:12
Energy-Selective Radiography A Review,ties of the transmitted radiation add a novel dimension to classical radiography, and provide more information than a measurement over a single arbitrary spectrum for the same radiographie exposure. The central questions are: How clinically relevant is this added information? How can measurements be饶舌的人 发表于 2025-3-26 06:38:44

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
