    Abstract: The invention relates to a soft tissue filter arrangement in X-ray imaging of a patient's skull by means of a chefalostat, wherein a patient (P) is by means of ear plugs (5) or the like supports preferably fixed relative to imaging coordinates as well as by means of a nasion and/or forehead support (6) set in a determined position and location between an X-ray source (1) and a film (4) or the like imaging medium and wherein the X-ray source is provided with diaphragm (2) for directing X-rays to the patient and restricting them to a proper sized beam (3) for imaging. The arrangement comprises preferably V-shaped filter means (7) whose position relative to the soft tissues of a patient's face in a cross-sectional plane perpendicular to the X-ray beam is adapted to be set on the basis of a distance (D) between said ear plugs (5) or the like supports and said nasion and/or forehead support (6) or on the basis of a patient's skull dimension correlating sufficiently well therewith. The nasion and/or forehead support (6 ) can be preferably provided with control elements and a scale by means of which the control elements (8) of said filter means (7) can be adapted to be controlled for producing an image having optimum patientwise exposure.

    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).
