Abstract

PURPOSE
We created an 'AAPM TG18 Evaluation Tool' and we determined its usefulness for the quality control of a diagnostic monitor.
MATERIALS AND METHODS
We created an evaluation tool (the AAPM TG18) for conducting quality control of a diagnostic monitor, and we evaluated the measurement items of the AAPM TG18 evaluation tool. The measurement items were geometric distortion, fixed quantity assessment and visual assessment of the veiling glare, and we carried out adjustment for the luminance meter 0% calibration, which was used to revise the diagnostic monitor DICOM LUT.
RESULTS
With the AAPM TG18 Evaluation Tool, we measured the 2-dimensional length when evaluating the quantitative geometric distortions in the TG18-QC test pattern, and we measured the veiling-glare ring response function, which provided information regarding the spatial extent of the luminance spread, and this measurement of the can be performed using the TG18-GV pattern. Additionally, the AAPM TG18 Evaluation Tool can be used for sensor calibration to standardize the basic rate of 0% luminance when performing periodic calibration.
CONCLUSION
The evaluation tool is a very useful for easily evaluating many of the examination items of the AAPM TG18 for performing quality control of a diagnostic monitor.
