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.

Abstract: Disclosed is automated setting of x-ray technic factors (e.g., KV, MA and exposure time) on the basis of (a) automated determination of the thickness of the body part to be imaged by a non-contact ranging system, (b) push button selection for the type of examination, and (c) push button selection for the type of body physique. The automatically determined technic factors and/or thickness are displayed to allow for manual override, and other failsafe features are provided as well. For better results, the ranging transducer is in the path of, and aligned with the axis of, the x-ray beam while producing ranging information, but is out of the x-ray beam path for the actual x-ray examination. An interlock is provided so that the x-ray beam is not on when the ranging transducer is in the beam path.

Abstract: Disclosed is automated setting of x-ray technic factors (KV, MA and exposure time) on the basis of (a) automated determination of the thickness of the patient part to be imaged by a non-contact, sonic ranging system, (b) push button selection for the type of examination, and (c) push button selection for the type of patient physique. The automatically determined technic factors and/or thickness are displayed to allow for manual override, and other failsafe features are provided as well.
