Konzentrationsbestimmung mittels RFAlso potentially offer improved means of acquiring, storing, and handling images when compared to present film-based angiography. It is therefore expected that in many applications the film will eventually be replaced by digital photoelectronic methods of X-ray image acquisition, archiving, and communication..textile 发表于 2025-3-23 18:26:19
Strahlungsregionen der Röntgenröhresubtracted from each other to form the final difference image, one taken from among those containing little or no contrast, and another taken at or near peak opacification. Because the two images are acquired at different times, the process is called temporal subtraction.PURG 发表于 2025-3-24 00:03:39

Noise Analysis in Digital Radiography,ain. The development of electronic X-ray detectors and in particular digital video subtraction systems has added much complexity to noise analysis. Due to the many new noise sources present, noise analysis now requires new evaluation criteria and techniques.多山 发表于 2025-3-24 12:24:18
Energy-Selective Radiography A Review, combined to provide an improved image or to isolate valuable and previously unobtainable information? How can imaging systems be constructed to acquire energy-selective measurements? What are the noise properties of energy-selective images, and how do they compare to conventional images?Antioxidant 发表于 2025-3-24 17:42:29

Digital Radiography Overview,cessing functions applied. 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
