ABSTRACT

Objective:

To discuss the test methods and the application value of detective quantum efficiency (DQE) in upgrading of DR based on flat panel detector(FPD).

Methods:

Combining the dose of incident X-rays with the image brought by flat panel detector. According to the international electrotechnical commission IEC 62220-1 standard method, the tungsten imaging,and combined with the relationship between the FPD and incident X-ray air kerma, using DQEPro equipment and software to calculate the result of the three different types of FPD.

Results:

The experiment proves that the basic performance of flat panel detector is known definitely by testing the DQE. DQE can reflect the quality of imaging performance in different types of flat-panel detector.

Conclusion:

The upgrading of DR based on flat panel detector and the DQE testing can be a better technical basis for DR measurement performance, then it can be ensure the quality of DR upgraded in diagnostic imaging.
