Abstract
An X-ray spot filmer is disclosed including a system for cyclically shifting a grid assembly interposed between an X-ray source and a film cassette. The system comprises an electrically energizable grid assembly actuator and an actuator controller for energizing the actuator to cyclically shift the grid assembly. The actuator controller includes actuator energizing output circuitry effective to govern the direction and speed of operation of the actuator in response to a control signal and control signal generator circuitry for producing control signals effective to govern operation of the output circuitry including an oscillator for producing a cyclically varying control signal which causes cyclic grid assembly shifting.
