摘要：PCT No. PCT/SE90/00104 Sec. 371 Date Aug. 20, 1991 Sec. 102(e) Date Aug. 20, 1991 PCT Filed Feb. 15, 1990 PCT Pub. No. WO90/09147 PCT Pub. Date Aug. 23, 1990.In connection with X-ray or like examination there is used a cassette holder arrangement which is carried by a frame structure (7) by means of pivotal arms (4) which are capable of being swung in the horizontal plane, such as to adjust the position of the cassette in the vertical direction. The arrangement enables pictures to be taken of a sitting patient in mutually perpendicular directions, with the aid of a radiation source (2). The cassette holder (3) can be swung between the exposure positions in a circuit path around the sitting patient, by activation of one of the arms (4). To this end there can be used a parallel linkage (11) which is operative to guide the cassette holder during this pivotal movement. the cassette holder is fixated relative to one of the arms (4), by means of a locking device (8), which is released when wishing to pivot the cassette holder. The invention also relates to a cassette holder arrangement of the aforedescribed kind.
