During the intraoperative radiograph generation process with mobile image intensifier systems (C-arm) most of the radiation exposure for patient, surgeon and operation room personal is caused by scattered radiation. The intensity and propagation of scattered radiation depend on different parameters, e.g. the intensity of the primary radiation, and the positioning of the mobile image intensifier...

Many scattering experiments in which a beam radiation or particles are sent into a material that scatters them have a number of features in common. (We shall use the word radiation to refer to the thing that is scattered.) • The radiation is a wave that satisfies a wave equation. • The incident beam is collimated (moving in one particular direction). • The incident beam is monochromatic (a narr...

introduction: one of the most important parameters in x-ray ct imaging is the noise induced by detected scattered radiation. the detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. the magnitude and spatial distribution of the scattered radiation in x-ray ct should be quantified for development of robust scatter...
