In this project RCMs were applied to all these regions listed in Table 7.1 with the exception of the chest region. Examples of images with and without RCM are provided and discussed in this chapter. Appropriate and inappropriate use of factors that alter RCMs is also discussed, together with a comparison of RCM and other techniques used for dynamic range control. Specifically applied digital RC...

The general practitioner working in his consulting room or his patient's home has a strictly limited range of diagnostic facilities available to supplement his clinical skills and experience. As long ago as 1946 the Annual Representative Meeting of the British Medical Association recommended that wherever possible, hospital departments of pathology and radiology should give direct access facili...

endobronchial tuberculosis and chest radiography i read, with interest, the article entitled “clinical and para-clinical presentations of endobronchial tuberculosis” by ahmadi hoseini h. s. et al. (1) published in this journal. i would like to focus on some details about the chest x-ray of patients as elaborated by the authors in the results section. accordingly, the findings of chest radiograp...

Objective- In this study, the general anatomical features of the digestive tube and the transit time of the digestive tube of the Zarudni’s spur-thighed tortoises were examined by contrast radiology. Design - Experimental study. Animals - 4 adult female Zarudni’s Spur-thighed Tortoises (Testudo graeca zarudnyi). Procedures- At a temperature of 25-27°c a set of dorsoventral rad...

PURPOSE This laboratory study compared visual-tactile examination with conventional radiographs, digital radiographs, and laser fluorescence in the detection of occlusal occult caries on extracted premolar teeth. METHODS Extracted premolars without obvious caries or restorations were collected from school dental clinics. Occlusal surfaces of 320 extracted premolars were examined visually with...

the gastrointestinal tract to evaluate because of its long length, complex looped configuration, and also because of its distant location. Only the proximal portion of the jejunum and the terminal ileum can be examined with the use of upper gastrointestinal endoscopy and colonoscopy. Thus, other examination tools such as small bowel follow-through, enteroclysis, capsule endoscopy and double-bal...

An x-ray radiography technique based upon phase contrast imaging using a lithium fluoride detector has been demonstrated for goals of high energy density physics experiments. Based on the simulation propagation an free-electron laser beam through test-object, visibility phase-contrast image depending object-detector distance was investigated. Additionally, metrological capabilities crystal as w...
