Abstract:
An X-ray apparatus has motors for moving its components in different directions. Sensors are provided to detect a collision between a motor driven component and an object, such as a patient being examined. In response to a collision being detected, a normal motor power supply is disconnected from the motor and another power supply is connected to the motor to move the component in the reverse direction. A safeguard is incorporated to insure that both power supplies cannot be coupled to the motor at the same time. For components which can strike a patient when moving in either of two directions, different collision sensors are provided for each direction. For this configuration, a mechanism also is provided to inhibit the connection of the other power supply when collisions are simultaneously detected each direction of component movement.
