CT CT CT apparatus and CT scanning method using the same

摘要

The present invention relates to a gantry having an opening for receiving an object to be inspected at its center, an x-ray generating part provided at a gantry part for generating a laser beam, and a gantry part provided at the gantry part at a position facing the x- A CT photographing unit including an X-ray detecting unit for detecting the laser beam transmitted from the X-ray generating unit and transmitted through the subject, and a gantry unit for turning around the subject in a circumferential direction and detecting a FOV of the subject and a tangential laser beam generating unit for irradiating a non-transmitting tangential laser beam in a tangential direction of the inspection target, and a FOV verifying unit for checking whether the inspection target is located within the FOV. According to the above description, the FOV of the subject can be confirmed by irradiating the tangential laser beam to the FOV set by the operator, thereby improving the reliability of the FOV. By measuring the distance from the subject to the subject, It is possible to set a corresponding optimal FOV, thereby ensuring clear and high-quality image data.
