The invention concerns an X-ray imaging apparatus for imaging a skull or a partial area of the skull, which apparatus comprises between the X-ray source and detector a patient support means (). The patient support means () comprise a rear rest structure () containing a support part () arranged to get positioned at occipital area and whose connection to the X-ray apparatus is realized such that the support part () of the rear rest structure moves, when adjusting its position, on a line or on a plane whose angle with respect to the horizontal plane is between 15-25 degrees.

X-ray imaging apparatus and patient support arrangement

The invention relates to positioning a volume to be imaged for computed tomography imaging. According to the invention, at least two optical cameras () are used for taking a photo or for live imaging an anatomy from different directions. A volume positioning indicator () is shown in connection with these images, the volume positioning indicator () indicating the location of the volume within the area imaged by the cameras () to get imaged by the computed tomography imaging apparatus ().

Computed tomography and positioning of a volume to be imaged

The invention concerns an X-ray imaging apparatus for imaging a skull or a partial area of the skull, which apparatus comprises between the X-ray source and detector a patient support means (). The patient support means () comprise a rear rest structure () containing a support part () arranged to get positioned at occipital area. The rear rest structure () comprises a first elongated supporting structure (), a first end of which containing said support part () and a second end of which extending to different side of the imaging station () than where said support part () is located.

X-ray imaging apparatus and patient support

The invention concerns an X-ray imaging apparatus for imaging a skull or a partial area of the skull, which apparatus comprises between the X-ray source and detector a patient support means (). The patient support means () comprise a rear rest structure () containing a support part () arranged to get positioned at occipital area and a safety mechanism () in an area between its mounting point to the X-ray imaging apparatus () and said support pan (). The safety mechanism () is arranged to go off when a force greater titan predetermined is acting on said support pan () and to release said support part () from its patient support position.
