CT radiography apparatus

The invention relates, in particular, to structures of dental and medical cone beam computed tomography (CBCT) imaging apparatus. The basic construction of the apparatus includes a substantially vertically extending frame part () which supports via a horizontally extending support construction () the X-ray imaging means () of the apparatus. The apparatus includes a patient support structure () which extends substantially in parallel with and is essentially of the same length as the substantially vertically extending frame part ().

CT imaging apparatus

The invention relates, in particular, to features of an apparatus applicable for use in the context of dental or medical CT imaging. The apparatus comprises a two longitudinally extending frame parts, a support constructionfor an X-ray sourceand an image detectorand a first driving mechanismarranged to move them about a rotation axis. A patient supportcomprising a patient support surfaceis mechanically connected to the first of the substantially longitudinally extending frame parts, which extends substantially in parallel with the first longitudinally extending frame partand having at, or at the proximity of its two edgeswhich extend in the same direction as the first longitudinally extending frame parti) at least one support elementor ii) at least one connecting constructionfor at least one support element, the support elementbeing an accessory designed for a patient to hold on or help the patient to be still during an imaging exposure, or to help keeping a patient be still.

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 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.
