| 摘要 |
Apparatus according to the present invention is provided for conducting cranial X-ray tomography and radiography of human subjects and includes a horizontally oriented, motor driven rotatable shaft for imparting controlled rotation to an elongate support member having an X-ray source and film holder provided at opposed end portions thereof. The apparatus includes a cephalometer which supports the head of the subject at a fixed position during X-ray tomography and radiography procedures. The horizontal rotary shaft of the apparatus is controllably movable laterally, preferably horizontally, between successive X-ray exposures to achieve successive tomographic images on the X-ray film representing sections or cuts of the cranial site of interest.
