POWER TRANSFER APPARATUS PARTICULARLY FOR COMPUTERISED TOMOGRAPHIC SCANNER

摘要

A CT scanner comprises a static gantry member and a rotatable member mounted on the gantry member for rotation about a central axis. A stationary power supply is associated with the gantry member for supplying power to an x-ray tube mounted on the rotatable member. An inductive coupling is responsive to the power supply for transmitting electrical power to the x-ray tube from the gantry member. The x-ray tube is operable in response to the transmitted power for producing x-ray beams passing through the central axis.
