A foot pedal switch for manually operating a medical diagnostic apparatus has a switch housing and a switching rocker with a neutral position that can be rotated around a rotational axle, with the rotational axle projecting from the housing such that it forms a bearing point of the foot pedal switch with its free end. The switching rocker is angled twice, and the axle has a semicircular outer region, so that, viewed laterally, a central rectangular surface of the switching rocker is secured on the straight surface of the rotational axle in a horizontally oriented fashion, while two lateral switching surfaces, which are rounded in front, project upwardly.

A radiator has an x-ray tube disposed in a coolant-filled housing formed by a tank and an insertable closure for the tank. The x-ray tube is provided with an asymmetrical cooling member disposed in the region of a heat exchanger. Guides are provided which effect circulation of the coolant heated at the cooling member and cooled in the heat exchanger. The coolant circulation is promoted by superimposing thermal convection in the coolant, thermal conduction in the asymmetrical cooling member, and heat flow induced by the electrical fields which are present during the normal operation of the radiator. The result is that the surface temperature of the entire x-ray radiator is substantially the same, independently of the orientation of the radiator.

X-ray radiator

An x-ray radiator has an x-ray tube disposed in a coolant-filled housing formed by a tank and an insertable closure for the tank. The x-ray tube is held in a tube carrier, which is mounted to the insertable closure so that the position of the tube carrier, and thus of the x-ray tube, can be adjusted relative to the insertable closure.
