ABSTRACT:
The invention relates to a patient support system in a narrow-beam tomographic X-ray apparatus, having a fixed frame fitted with a substantially vertical member (1), means (7, 8, 9) mounted on the frame for supporting a patient's head, said means being adapted to hold a patient's head (P) steady during the imaging session, as well as a bearer bar (3), fitted with a source of X-radiation (4) and imaging instruments (5) on the opposite sides relative to an object to be imaged and said bar being adapted in a known manner to perform rotational or combined rotational linear movement for scanning a predetermined layer to be imaged. In order to facilitate patient positioning and to secure proper positioning of a patient, said head support means (7, 8, 9) are set in a manner that the medial sagittal plane (S) of a patient supported thereby does not intersect said vertical frame member (1).
