Abstract:With the improvement of digital medical imaging technology, medical imaging diagnostic display system is gradually replacing the traditional screen glue system, becoming the main tool for clinical diagnosis of medical imaging. The actual display effect will directly affect the doctor's diagnosis. Reliability and accuracy. The GSDF consistency of the DICOM standard is the most important indicator for evaluating medical displays. It is different from the traditional full darkroom test. By providing 5 sets of ambient light under different illumination conditions, the actual use scene of the reading room is simulated. When the illuminance of the ambient light exceeds a certain level, the brightness response error is significantly increased, and the dark-level information describing the details of the medical image has the greatest influence.
