Abstract

PURPOSE:To expose optimal amount of X-ray by detecting the strength of X-ray passed through the object from the start, then comparing it with a referential level and controlling the rising speed of bulb voltage automatically and instanteneously to eliminate the difference. CONSTITUTION:A photo-timer 13 will integrate the strength of X-ray passed through a object 10, and when it reaches to predetermined level a circuit breaker 14 is functioned to stop the exposure of X-ray. The output of photo-timer 13 proportional to the strength of X-ray after passing through the object is compared by an X-ray strength comparator 22 with a referential level from an X-ray strength setter 23. The output from the comparator 22 is provided to an adder 25 to control the voltage rising speed of X-ray tube.
