Computed radiography is without doubt one of the such a lot promising electronic radiography strategies, and is predicted to exchange the normal monitor movie radiography within the close to destiny. This e-book is the 1st textbook on computed radiography written via eastern authors and describes easy applied sciences and medical effects got at a variety of hospitals. There are greater than 60 CR platforms operating in medical environments in Japan. in spite of the fact that, as but there should not such a lot of platforms operating open air Japan. This ebook is, for that reason, a superb creation to the recent expertise and perform of the CR procedure everywhere in the world.

Greater utilization of the CR system as a file For the effective utilization of files, it is considered necessary to examine applications and sometimes • Fig. 6. Filing system for CR images also to introduce new systems. In routine applications, the designation ofkey images, the use of datacompressed images, the means of data compression, and reediting from active to permanent files are some of the factors that need to be examined. The future outlook of the CR system has been reviewed. To meet social demands, such as reduction of medical costs, computerization of the medical system, rationalization of medical services, improvement of diagnostic performance, profitability, better services, the CR system is expected to play an important role, and it is also expected that it will be one of the modalities used in future systems, such as PACS.

Image subtraction technique Other image-processing techniques Digital subtraction angiography In the field of digital subtraction angiography (DSA), CR is competing with the older I. -TV technique. -TV in terms of the following three properties: Wider field of image. 1. tube. In the case ofCR, an Imaging plate (IP) rapid changer has been developed to allow the use of an imaging plate of a size equal to the film usually used in angiography. Easy digitalization of X-ray image data with CR has resulted in substantial progress in studies related to X-ray image processing.

3c shows two small rounded shadows in the lower outer side and under the diaphragm. Only careful inspection of Fig. 3a reveals the presence of such small rounded shadows in the same area. Putting aside the question as to whether these rounded small opacities are a metastatic focus, they are easily detectable on low-frequency range- enhanced images, while they are absent on highfrequency range-enhanced images.
