Patent ID: 7424091

Claim:
A combined panoramic, CT (Computed Tomography) and cephalometric photographing apparatus comprising: a) a base; b) a supporting pole standing on the base; c) an elevation member mounted on the supporting pole in such a way as to elevate and displace in a vertical direction; d) a panoramic and CT photographing part mounted on the front surface of the elevation member; and e) a cephalometric photographing part connected to a side of the elevation member; wherein the panoramic and CT photographing part includes: 1) a rotary arm supporting member connected to the front upper portion of the elevation member; 2) a rotary arm supported by the rotary arm supporting member and arranging an X-ray source part for generating X-rays and an X-ray sensor part thereon in such a way that the X-ray source part and the X-ray sensor part are opposed to each other, the X-ray sensor part having a panoramic sensor and/or a CT sensor for detecting X-rays which are generated from the X-ray source part and pass through an object; 3) rotary arm driving means interposed between the rotary arm and the rotary arm supporting member for driving the rotary arm; and 4) an X-ray source part driving means mounted at a location where the rotary arm and the X-ray source part are connected with each other, wherein a distance between the X-ray source part and the X-ray sensor part arranged opposed to each other with respect to the rotary arm is variable, wherein the cephalometric photographing part includes: i) a cephalometric sensor part for detecting X-rays which are generated from the X-ray source part and pass through the object; ii) a horizontal arm for arranging the cephalometric sensor part is mounted at a side thereof; and iii) a connection member for connecting the horizontal arm to a side of the elevation member, wherein the X-ray sensor part is fixed on the rotary arm, and wherein the X-ray source part is horizontally moved in a direction to get near to the X-ray sensor part or in a direction to get away from the X-ray sensor part without regard to the rotary arm, wherein the X-ray sensor part includes a sensor mounting part to attach and detach a sensor, wherein one of the panoramic sensor and the CT sensor is mounted on the sensor mounting part, wherein the X-ray sensor part includes a first sensor mounting part for mounting the panoramic sensor and a second sensor mounting part for mounting the CT sensor.
