A multiple examination arrangement has a number of imaging systems, including at least an angiography system, a CT system and an MR system arranged in a room such that a patient lying on a patient bearing table can be selectively examined without repositioning in one of the imaging systems by a relative movement of the carrier of the imaging systems and the patient support table.

X-ray diagnostic apparatus has a beam transmitter and beam receiver mounted opposite one another on a curved holder. In a first operating mode, the curved holder is formed by at least a first circular ring segment on which the beam transmitter and the beam receiver are mounted. In a second operating mode, a second circular ring segment is coupled to the first circular ring segment so that a closed ring results. Displacement arrangements, as well as energy supply connections, are provided for the beam transmitter and the beam receiver, and a signal transmission arrangement for the beam receiver is provided, so that the beam transmitter and the beam receiver can be controlled, positioned opposite one another, so as to rotate around an examination subject. With this X-ray diagnostic apparatus, both transirradiation exposures and computed tomography exposures can be produced.

A medical therapy system includes an x-ray system for locating a treatment site in a patient and a therapy device for administering medical therapy. Apparatus is provided for supporting and positioning the therapy device, which includes a computer into which the position of the therapy device can be entered with reference to the x-ray images, with automatic positioning of the therapy device being undertaken based on the entered data.

A positioning control system controls the shifting of one of a plurality of radiation filters into the ray path. Transducers provide an electric density signal which is dependent upon the density of the examination subject. The control system has an electromotor activated by a control circuit to which the density signal is applied and which activates the motor corresponding to the respective density signal for the purpose of selection of the correct filter. The transducers may be coupled with a device physically acting in compression on a body part of the patient to be examined such that the degree of resistance of the body part to compression is sensed by the transducers as a measure of patient density.
