Source position controller for multi source irradiation system

摘要

PURPOSE: A radiation source position control device for a multisource irradiator is provided to control the amount of irradiation of radiation by connecting a multisource holder rod to a freely moving lift according to the operation of a rodless cylinder, thereby selectively moving the location of the multisource holder rod. CONSTITUTION: A pair of cylinder frames and radiation source location setting frame(30) are separately installed to face the upper part of a base plate. A rodless cylinder(40) is connected between a pair of end blocks which are installed to be spaced apart in the up/down part of the cylinder frame. A lift(50) is attached to the front side of a moving block which is movably combined along the rodless cylinder and a guide rod(43). A rotary joint is installed in a rodend bearing which is combined with the lower side of a lift. A stopper guide is attached to the top and bottom of the radiation location setting frame with a uniform space.
