The objective of the present invention is to effectively achieve, by a low-cost system, a simple change of a sensor and an adjustment of a distance according to an imaging mode, so as to acquire a panoramic image, a CT image and a cephalometric image by using a single device. To this end, the present invention provides a composite imaging device for dental diagnosis, comprising: a lifter fixed to the upper surface of a base; a column supported by the lifter so as to be provided such that the column can move vertically along the lengthwise direction of the lifter; a support arm coupled to a front end part of the column; a rotary arm (gantry) provided rotatably on a driving unit coupled to a one-side front end part of the support arm, and provided with an X-ray generator; a sensor unit provided on the rotary arm so as to detect X-rays emitted from the X-ray generator; a sensor unit rotatably provided on the rotary arm and having a sensor for detecting X-rays emitted from the X-ray generator; and a sensor control means for performing a sensor change and a distance adjustment of the sensor unit according to an imaging mode. |
