WebX-Ray Physics: Magnification and Collimation in Radiography. This simulation illustrates the effects of changing various settings on a fluoroscopy or radiography (x-ray) system on image quality and patient dose. Note that it does not take into account factors such as kV, filtering, anti-scatter grid, patient thickness, or patient anatomy. WebA Geometric Unsharpness Calculator for Industrial Radiographers. You just have to enter the Source Side of the Weld or Object being radiographed to the film and source distances and also enter the source size (diagonal). It will then calculate the Geometric Unsharpness (Ug) for you! No more have to look up the formula and pulling out a calculator.
