Abstract:
Objective To design an automatic exposure control circuit for X ray equipment to improve the performance of equipment and the quality of film. Methods The device acted in series control. During exposuring process,the X ray reaching the film through patient body was measured by ray sensor. After it was treated with integration, amplification and contrast management,the signal of X ray quantity drived the device to cut off exposure circuit, so that the exposure time was automatic any controlled. Results The effect of the device has been proved by its application in several hospitals. Conclusion The device is simple and effective and has practical value.
