ABSTRACT:
An X-ray apparatus which is readily convertible for conventional radiographic or tomographic operation includes an X-ray source and an imaging device movably supported on opposite sides of a patient support. For tomographic procedures, the source and the imaging device are interconnected by shielded drive system components to effect coordinated movement of the source and the device. For conventional radiography, the drive components are disconnected to permit independent movement of the source and the imaging device. The drive components are disconnected for conventional radiography by lowering the X-ray source and by operating a latch located near the imaging device. The drive components are connected for tomography by raising the X-ray source and by operating the latch. Other improvements such as the use of rotary encoders to provide a digital readout of the location of a tomographic examination plane and to control the operation of the source during tomographic procedures are described.
