ABSTRACT:
The invention is related to a soft-tissue filter apparatus for a cephalostat, said apparatus being capable of positioning the patent (P) stationary for exposing radiographic images of the skull. The apparatus comprises an x-ray source (13) whose collimated (14) x-ray beam (XR) can be directed through the skull of the patient (P) onto an x-ray film (RF) contained in a cassette (23). The apparatus further comprises a soft-tissue filter assembly (10) in which to the region of one side (a) of the x-ray beam (XR) is placed an radiation-absorbing filter element (19) movable by means of a drive motor (15) transversely (B) to the x-ray beam (XR). The apparatus incorporates a light indicator unit (20) comprising a light source (25) capable of projecting onto the side of the face of the patient (P) a light marker line (LL) which is transferrable along the adjustment direction (B) of the soft-tissue filtering assembly. The light indicator unit (20) is equipped with a sensor (31) of the light marker line (LL) position, said sensor's positional information (U.sub.p) being adapted in the apparatus to control the position of the soft-tissue filter element (19) to the position relative to the patient (P) indicated by means of the light marker line (LL) projected by the light indicator unit (20).
