DIRECT DRIVE TYPE GANTRY FOR COMPUTER TOMOGRAPHIC APPARATUS

摘要

PURPOSE: A direct drive type gantry is provided to prevent noise caused due to the decelerator or chain, while shortening time for extracting image and obtaining high definition image. CONSTITUTION: A direct drive type gantry(100) comprises a frame(101) for supporting devices for obtaining image information; a stator(102) constituting a synchronous motor, and which is installed to the frame and has a plurality of coils arranged at the inner periphery of the stator so as to form a magnetic field; a rotor(103) constituting the synchronous motor together with the stator, and which is mounted in the stator, and has a plurality of permanent magnets arranged along the outer periphery of the rotor, and devices for obtaining image information arranged along the inner periphery of the rotor; and a control unit(104) electrically connected to the synchronous motor, and which controls speed of the rotor and transmits position of an X-ray tube.
