Abstract:
Objective To design a new X-ray sensor of iono-chamber type to achieve automatic exposure control(AEC) of the X-ray machine. Methods We designed the chamber acording to the ionization theory and the requirements of automatic exposure control. Results (1) The device had double-negative poles, so the distance between positive and negative poles was 1/2 shorter and its test-volume was equal to odd-negative pole. (2)It had good property of electromagnetism-resistance because of the double shielded design by double-negative poles and screen-rings.(3) Iono-chamber was made of low-density material, so it had low absorb-ratio of X-ray and could not form image on film. Conclusion The property of the device was steady and reliable. It had applying and spreading value.
