1. A dental or medical CT imaging apparatus, comprising:
a first longitudinally extending frame part extending in a first direction and comprising a first end and a second end;
a support construction extending from the longitudinally extending frame part in a second direction at least substantially perpendicular to the first direction, the support construction comprising a ring-shaped gantry connected to the first longitudinally extending frame part as non-rotatable about an axis extending in said second direction;
an X-ray source and an image detector which together form an X-ray imaging assembly mounted to the support construction;
a first driving mechanism arranged to move the X-ray imaging assembly about a virtual or physical rotation axis extending in parallel with said first direction;
a control system comprising an operation mode controlling the first driving mechanism and simultaneously the X-ray imaging assembly;
a patient support and a connection construction mechanically connecting the patient support to the first longitudinally extending frame part;
wherein the support construction includes at least one guiding construction configured to enable laterally moving at least either of the X-ray source and the image detector in relation to the support construction, said laterally moving comprising moving on a plane extending at right angles to said virtual or physical rotation axis, a range of said lateral movement of at least either of the X-ray source and the image detector comprising a base position and a first and a second extreme position, and wherein each of the first and the second extreme position is laterally disposed relative to the base position.
