title: [An APC 50 MA x-ray unit for mammography].
abstract: The main medical and engineering parameters of the unit are described, and its specific features as a tool for diagnosis of mammary gland diseases are considered. The following systems are described: for voltage switching in the main circuit, for the control and stabilization of the X-ray tube anode voltage, and the device for limiting the exposure time. The mathematical description of the dynamic properties of a closed system to control the anode voltage is proposed.
