Two transparent hemisphere-domes 1, 2, made of a strong, polymorphic material (plastic etc.) held together by screws so as to form a sphere. At the equatorial level of one of these, a circular disc of equal diameter is fitted which, at its centre region and along the axis of a diameter, has the supine impression 6 of the body of the neonate or infant for positioning the patient to be examined. On either side of the impression and along a direction parallel to its longitudinal axis and in contact with it there are longitudinal slot-sockets 18, 19 for placing an X-ray cassette for taking oblique X- rays (PROFILE) while there is another pocket 5 for an X- ray cassette in the back of the impression for taking frontal (FACE) X-rays. At its top each hemisphere-dome has an opening-door 8, 9 to attend to the patient and to handle the X-ray cassette. The whole rests by gravity, in "egg-eggcup" fashion, within a special concave housing. The seat-base 4 consists of a concave housing 13 and a horizontal plate 14 as a single, secure support. The sphere can be turned at will to take X-rays at any desired projection. |
