Operating Principles
X-ray is emitted when a high voltage is supplied to the X-ray tube assembly, which
frees electrons from the cathode.
They hit anode to produce an X-ray. The machine acquires images by emitting X-rays
continuously and rotates on the human tooth at different angles.
Images are acquired, computed, and recompiled to reproduce 2D or 3D images.
