TCM CBCT METHOD FOR ACQUIRING CBCT IMAGE USING TUBE CURRENT MODULATIONTCM AND SYSTEM THEREOF

摘要

According to an embodiment of the present invention, a method for obtaining a CBCT image by applying a tube current modulation (TCM) method includes: a step (a) of receiving pre-stored CT image data; a step (b) of calculating a damping value by radiation angle based on a specific data slice selected from the CT image data; a step (c) of calculating the total tube current amount for correcting the quality of a TCM CBCT image; a step (d) of calculating a tube current amount by radiation angle for TCM CBCT photography through the damping value; and a step (e) of controlling the dose of radiation emitted from the TCM CBCT photography in accordance with the tube current amount information by transmitting the information to a CBCT device.
