Classification: CPC A | IPC A

Claim 0:
1. An intraoral imaging apparatus for tomosynthesis imaging comprising:
a) an x-ray source having a primary collimator that defines boundaries of a radiation field;
b) a transport apparatus that translates the x ray source along a path for tomographic imaging;
c) an intraoral x-ray detector that defines an imaging area for the radiation field;
d) a positioning apparatus that correlates the position of the intraoral detector to the position of a secondary collimator;
e) one or more radio-opaque markers provided on a detector attachment that is coupled to the detector, the one or more markers configured to condition acquired x-ray images to relate the spatial position of the intraoral x-ray detector to the x-ray source position, wherein the one or more markers are disposed within the defined imaging area;
and
f) a control logic processor that accepts image data from the detector and determines the relative location of the source with respect to the detector according to detected marker position.
