Abstract
In order to develop a circuit arrangement for X-ray generators which are used especially for diagnostic purposes, having a high-voltage rectifier, whose preselectable tube voltage can be matched to the requirements, with a variable transformer and an X-ray tube connected thereto whose heating power provided by a heating voltage generator can be preset, the preselection of the tube voltage and the presetting of the heating power of the tube being capable of being carried out by means of a controller in accordance with the desired or necessary X-ray dose, such that the presetting can be carried out in accordance with the desired radiation dose power, radiation hardness and exposure duration in a simple manner even by personnel who have only been instructed, it being intended that the setting should be capable of being carried out in a simple manner using logos and symbols, it is proposed that a personal computer (PC) which is known per se be used for the presetting, which PC is connected via an interface to the controller of the X-ray generator in such a manner that the personal computer (PC) initially calculates the tube voltage and heating power for a desired X-ray dose of desired hardness, transmits this voltage and power via the interface to the controller and the time duration, tube voltage and heating current of the X-ray tube is set in accordance with the guidelines by the controller, with the aid of the actuating elements. <IMAGE>
