Abstract
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 (11) which supports via a horizontally extending support construction (12) the X-ray imaging means (14, 15) of the apparatus. The apparatus includes a patient support structure (18) which extends substantially in parallel with and is essentially of the same length as the substantially vertically extending frame part (11).
Claims20
A dental or medical CT imaging apparatus, comprising:
- a first substantially vertically extending frame part comprising a top end and a bottom end;
- a support construction extending essentially horizontally from the first substantially vertically extending frame part;
- an X-ray source and an image detector mounted to the support construction which together form an X-ray imaging means;
- a first driving mechanism arranged to move the imaging means, about an axis;
- a second driving mechanism arranged to move the support construction in a direction substantially parallel with a direction in which the substantially vertically extending frame part extends;
- a patient support;
- a control system;
- characterized in that the patient support is a structure mechanically connected to the first substantially vertically extending frame part and extending substantially in parallel with said first substantially vertically extending frame part and is essentially of the same length as said first substantially vertically extending frame part.
