WebHistorically, photographic films and plates have been used at the exit plane of the monochromators to detect the spectral patterns from analytes. The main advantage of this approach is its inherent multi-wavelength detection ability. Because photographic films and plates are area detectors with fantastic spatial resolution, the entire spectrum from a … To obtain an image with any type of image detector the part of the patient to be X-rayed is placed between the X-ray source and the image receptor to produce a shadow of the internal structure of that particular part of the body. X-rays are partially blocked ("attenuated") by dense tissues such as bone, and pass more easily through soft tissues. Areas where the X-rays strike darken when develop…
