Abstract: A medical diagnostic X-ray apparatus includes an X-ray source, a hollow carrier to which the X-ray source is connected, and a cooling device provided with a cooling device to cool the X-ray source during use of the X-ray apparatus. The cooling device is in direct thermal contact with the carrier, thus providing an efficient cooling mechanism for the X-ray source.

Abstract: The invention relates to a medical diagnostic X-ray apparatus (1) comprising an X-ray source (13), a hollow carrier (5) to which the X-ray source is connected, and a cooling mechanism (3) provided with a cooling means to cool the X-ray source (13) during use of the X-ray apparatus (1). The cooling construction (3) extends completely inside the hollow carrier (5) thus reducing the risk of leakage of cooling means.

Abstract: An X-ray stand comprising a generally arcuate swing arm (10) on which is provided an X-ray tube (15) in a stationary housing (14) and an X-ray detector (16). The detector (16) is hingedly mounted via a smaller arm (20) to the swing arm (10), so as to enable the smaller arm (20) to pivot relative to the upper end of the swing arm (10). The detector plate (16) is mounted to the free end of the smaller arm (20) by means of a joint (22) which enables the detector plate (16) to be pivoted relative to the smaller arm (20). In addition, the X-ray tube (15) is mounted on a pivotal carriage (15a) within the housing (14) such that it can be relatively tilted, and the carriage (15a) in or on which the X-ray tube (15) is provided is mounted within the housing (14) on a sliding mechanism (30) which permits the selective rotational movement of the X-ray tube (15) within the housing (14).

Abstract: The invention relates to a medical diagnostic apparatus (1) and to a hose (21) suitable for guiding connections in a medical diagnostic apparatus. The medical diagnostic apparatus (1) comprises a frame (5), a rotatable support (3), at least one connection extending between the frame and the rotatable support, and a hose (21) for guiding this connection. The hose (21) is provided with a chain (29) of reinforcement elements (31). The chain (29) extends mainly in the longitudinal direction of the hose (21). In the chain (29) the reinforcement elements (31) are connected to each other. These reinforcement elements (31) can also be rotated with respect to each other about an axis which is perpendicular to the longitudinal axis of the hose (21), while they are substantially rigidly connected in a direction along their rotation axis.

Abstract: The invention relates to a medical diagnostic device comprising a drive system (15) for positioning a radiation source (3) and a radiation detector (5) facing each other with respect to a target (9). The medical diagnostic device comprises a frame (11) and a support (1). Via a central position the support (1) can be rotated with respect to the frame (11) between a first and a second extreme position. The drive system comprises a first (19) and a second (21) guiding wheel. At least one of the guiding wheels (19, 21) is driven by a drive means (27). Furthermore the drive system (15) comprises a belt (17) which is connected to the support (1) by two connection points (23, 25). In the central position of the support (1) the belt (17) is guided over and along the first (19) and the second (21) guiding wheels so that a zigzag configuration of the belt (17) is obtained.

Abstract: A tomography device, which includes a frame, a table for supporting a patient to be examined, an X-ray source which is pivotable about a pivot shaft in order to direct the X-rays towards the table during operation, and a receiving plate which is displaceable relative to the frame in order to pick up X-rays emitted by the X-ray source during operation. The pivot shaft is journalled in a slide which is displaceable relative to the frame by means of a guide system. The slide also accommodates the receiving plate. Because the receiving plate is part of image intensifier, the image intensifier is connected to the slide, and the slide is displaceable relative to frame, radial movement of plate occurs in a plane which is parallel to the plane of frame.

Abstract: A medical diagnostic and/or therapy apparatus in the form of an X-ray apparatus, including a stand (2), a C-arm (4) and a patient table top (8) which is attached to the stand by way of a supporting arm (6). In order to enable the patient table top to be cleared very quickly from the C-arm (i.e. make it accessible from all sides), notably in trauma situations, the supporting arm of the patient table is rotatable about a vertical axis (22) with respect to the stand. The pivot (25) of the supporting arm is situated at the location of attachment of the supporting arm to the stand, so that when it is swung away, the table requires substantially less space in its longitudinal direction than in the prior art. Moreover, room then remains for an additional treatment apparatus in the treatment space, for example for a tomography arc (26) which can then be positioned around the swung away table top within a few seconds in the case of emergency.

Abstract: A medical diagnostic and/or therapeutic apparatus provided with a C-arc support (2) for, for example an X-ray source (4) and an X-ray detector (6). The support (2) comprises two complementary U-profiles (26) which are connected to one another by way of their flanges (28), using two rod-shaped parts (20) with grooves (24) which extend parallel to the axis of the rod-shaped parts (20) and receive the flanges (28). The flanges (28) are fixed in the grooves (24) by holes (30) which are provided in the rod-shaped parts (20), extend perpendicularly to the plane of the grooves (24), and overlap the grooves (24), in said holes there being arranged pressure pieces (40) which are interconnected by a connection rod (46) which interconnects two oppositely situated pressure pieces (40).

Abstract: An X-ray examination apparatus comprises a mobile base on which a table top is also mounted. An X-ray source and detector are secured to the base on a pivotal support. For transporting the X-ray examination apparatus, the support is rotated through 90.degree. with respect to the base, so that the overall width of the apparatus does not exceed the wheelbase of the base. A radiation shielding control console is secured to the wheelbase base so that it can be swung aside.
