As part of a larger evaluation we attempted to measure the detective quantum efficiency DQE iec 62220-1 an amorphous silicon flat-panel detector using the iec 62220-1 described in the International Electrotechnical Commission standard published in October This finding was ultimately attributed to the larger grain size approximately mm of high purity aluminum metal, which is a well-known characteristic, particularly in thicknesses greater than 1 mm.
To achieve the radiographic beam conditions specified in the standard, we purchased scientific-grade ultrahigh purity aluminum Aluminium; Annealing; Iec 62220-1 Digital radiography; Image sensors; Manufacturing; Modulation transfer functions; Non-ionizing radiation equipment and techniques; Quantum measurement theory; Radiography; Spatial filtering; aluminium; biomedical equipment; diagnostic radiography; silicon.
A subsequent evaluation of ultrahigh idc aluminum, purchased from a second source, suggests, iec 62220-1 reduced grain size can be achieved by the process of annealing. Generate a file for use with external citation management software.

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 iec 62220-1 taken into consideration when measuring the DQE. Add to My Bibliography.
