Abstract
An x-ray machine in which an electronic network automatically sets the KV for the power to the x-ray tube, by using a transformer with separate secondary windings which can be selectively included in a series circuit through relays controlled by a binary sequence, in response to operator-selected KV control signal, in a system in which the operator selects the mAs setting and the other technic factors (except KV) are automatically selected.
