A dental or medical CT imaging apparatus including a first longitudinally extending frame part. A support, construction extends substantially perpendicularly from the longitudinally extending frame part. An X-ray source and an image detector which together form an X-ray imaging assembly are mounted to the support construction. A first driving mechanism is provided to move the X-ray imaging assembly about a virtual or physical rotation axis. A control system having at least one operation mode that simultaneously controls the first driving mechanism and the X-ray imaging assembly is provided. The support construction includes at least one guiding mechanism configured to enable laterally moving at least one of the X-ray source and the image detector in relation to the support construction. A range of the lateral movement of at least one of the X-ray source and the image detector includes a base position and a first and a second extreme position.

CT imaging apparatus

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.

X-ray imaging apparatus and patient support safety mechanism

The invention relates to a medical computed tomography imaging apparatus which is especially designed to enable cranial imaging. The structure of the apparatus includes a gantry () comprising imaging means () and a positioning support () which positioning support () is arranged to position the patient's cranium for exposure such that, when exposed, the cranium is scanned by a radiation beam substantially parallel with a plane formed by the facial area of the cranium and substantially only in an area on the facial side of the cranium.
