A subsequent evaluation of ultrahigh purity aluminum, purchased from a second source, suggests, that reduced grain size can be achieved by the process of annealing. Qualitative evaluation of flat field images acquired at 71 kV RQA5 beam quality with 21 mm of ultrahigh purity aluminum filtration demonstrated iec 62220-1 low frequency mottle that was iec 62220-1 and was not ifc when the measurement was repeated at 74 kV RQA5 beam quality with 21 mm of lower-purity aluminum Aluminium; Annealing; Calibration; Digital radiography; Image sensors; Manufacturing; Modulation transfer functions; Non-ionizing radiation equipment and techniques; Quantum measurement theory; Radiography; Spatial filtering; aluminium; 622201 equipment; diagnostic radiography; silicon.

Our observations of markedly visible nonuniformities in images acquired with high purity aluminum filtration suggest that the uniformity of filter materials should be carefully evaluated and taken into consideration when measuring the DQE. As part of a larger evaluation we attempted to measure iec 62220-1 detective quantum efficiency DQE of an amorphous silicon flat-panel detector using the method described in the International Electrotechnical Commission iec 62220-1 published in October Abstract As part of a larger evaluation we iec 62220-1 to measure the detective quantum efficiency DQE of an amorphous silicon flat-panel detector using the method described in the International Electrotechnical Commission standard published in October To achieve the radiographic beam conditions specified in the standard, we 622220-1 scientific-grade ultrahigh purity aluminum This finding was ultimately attributed to the larger iec 62220-1 size approximately mm of high purity aluminum metal, which is a well-known characteristic, particularly 622200-1 thicknesses greater than 1 mm.
