ABSTRACT:
In the illustrated embodiment the mAs indicator has a rectangular window for exposing a printed mAs value in accordance with discrete settings of x-ray tube current and photographic exposure time. The x-ray tube current selection controls a mask with a stepped series of small apertures which successively register with different portions of the mAs indicator window. The exposure time selection may control the angular position of a cylinder which positions successive rows of mAs product values with the mAs indicator window, such that the particular mAs value which is visible through the aligned mask aperture will represent the product of the x-ray tube current setting and the exposure time setting. In the illustrative embodiment, the mask comprises a flat plate which is driven in response to angular movement of the x-ray tube current selector knob by means of a pin and slot opening. The cylinder is driven by means of the rotary exposure time selector knob by means of a simple cord drive.
