Abstract:
1. A panoramic tomography X-ray apparatus, comprising: an X-ray generator for emitting X-rays; an X-ray detector including a plurality of detection elements outputting signals corresponding to intensity of the X-rays to be incident thereon; a revolution mechanism for causing the X-ray generator and the X-ray detector to be opposed to each other with an object including a dentition therebetween and allowing the X-ray generator and the X-ray detector to revolve about the object; a storage part for successively storing and accumulating the signals output from the X-ray detector as an image information when the X-ray generator revolving emits the X-rays; an image information processing part for receiving the image information from the storage part and superimposing overlapped portions of images along a tomographic plane corresponding to a dental arch to generate a panoramic tomographic image; a display part for displaying the panoramic tomographic image generated by the image information processing part; a position setting part for setting, in a median portion including a median line of the object, a position of the tomographic plane regarding a depth direction of the object with a use of at least one image for position setting comprising a median-portion X-ray image including the median portion; and an operation part for receiving an input of an operation by an operator, wherein said position setting part receives designation of a position of said tomographic plane regarding the depth direction at a partial area including said median portion with respect to said image for position setting via said operation part, and said image information processing part causes said display part to display a new panoramic tomographic image generated by changing position of the tomographic plane corresponding to the dental arch along said depth direction in accordance with a designated position by said designation received via said operation part.
