PROBLEM TO BE SOLVED: To make the height of the lower end of a working range of electric imaging means uniform both in CT imaging and in panorama imaging and to rotate the electric imaging means to set the center of the electric imaging means at a desired position. SOLUTION: An X-ray imaging apparatus includes a sensor rotating mechanism 8 for rotating an area sensor 10 so that the diagonal line of a sensor unit 10b is positioned vertical during a panorama imaging mode. The sensor rotating mechanism 8 includes: a first guide mechanism 8a for moving the corner part of the sensor unit 10b in the horizontal direction; and a second guide mechanism 8b for guiding the center of the sensor unit 10b in a predetermined direction. The first guide mechanism 8a, in particular, guides an intersection 112 of the lower side 111 of the working range 10P of panorama imaging and one side 100 of the sensor unit 10b which is the lower side in CT imaging in the horizontal direction, to thereby make the height of the lower end of the working range equal in both imaging modes. The second guide mechanism 8b guides the center of the sensor unit 10b along a guide rail 87 to set the center of the sensor unit 10b at a desired position. COPYRIGHT: (C)2011,JPO&INPIT |
