Abstract: An X-ray apparatus in which the X-ray source and the image recording device can be detachably interconnected by means of a coupling device. The coupling device includes a coupling rod which slides telescopically in a tube. The coupling device is uncoupled by pressing the supporting arm of the X-ray source downward, thus unblocking a blocking device which connects the coupling rod to the supporting arm. By subsequently raising the supporting arm while latching the blocking device, the coupling rod is left in a storage position. Recoupling of the coupling rod to the arm is effected by releasing the latch of the blocking device and by pressing the supporting arm downward again. It is not necessary to walk around the X-ray apparatus for coupling or uncoupling.

Abstract: An X-ray tube for generating two focal spots displaced with respect to each other and a medical device using such X-ray tube are proposed. The X-ray tube (1) comprises a cathode (7) and an anode (9) wherein the cathode (7) comprises a first electron emitter (15) adapted for emitting a first electron beam (17) for generating a first focal spot (25) on the anode (9) and a second electron emitter (19) for emitting a second electron beam (21) for generating a second focal spot (27) on the anode (9). Therein, each electron emitter (15, 19) comprises an associated switchable grid (37, 39) for blocking the respective emitted electron beam (17, 21). In order to realize a desired displacement of the first and second focal spots (25, 27) in a y-direction, the first and second electron emitters (15, 19) may be displaced in the z-direction. Due to the focal spots (25, 27) being displaced in y-direction, an overall resolution of for example a high quality CT scanner may be significantly enhanced.
