Knowledge of the output spectra can assist in both improving these sources and in analyzing the imagery. Consequently, we have begun developing a spectrometer for this regime, which we refer to as the Collimated Step-wedge Spectrometer (CSS). It is based on a set ...
It has been fabricated step wedge-based resin as a substitute for soft tissue on digital radiographic systems. It is need to be varied in expose factor and focus to film distance (FFD) to produce a good image contrast in digital radiography systems. Radiograph image of step wedge which ...
The accuracy of the step-wedge test in detecting eighteen machine and film-processing variables was measured with a densitometer. Possible comparisons with measurements made by an accepted densitometric method used in medical radiography showed similar results. The test can be used in lieu of more ...
X−RAY RADIOGRAPHYDIGITAL SYSTEMSIMAGE INTENSIFIERSTELEVISIONX−RAY EQUIPMENTIn order to determine accurately the relative x‐ray intensities transmitted through the different steps of an aluminum stepwedge and incident on an image intensifier (II)–TV digital system, we used a 100‐mm camera which...
stepwedgebootstrap methodcalcium phosphateA method for measuring the characteristic curves generated by the mammography imaging systems has not yet been well established due to poor quality control over X-ray exposure in the range of kV values, which is lower than the conventional quality. In...
