Abstract: An intraoral x-ray system mountable to a dentist’s office wall including components movable to compensate for defects in the wall’s flatness or the wall not being sufficiently perpendicular to the floor. The system also includes monitoring and compensation capabilities to compensate for drift in the position of the system’s x-ray source or patient movement before and during x-ray imaging, thereby avoiding the need for the taking of additional x-ray images and exposing the patient unnecessarily to extra x-ray dose. Additionally, the system further includes a data/signal processing unit that allows the x-ray source to be precisely moved along a predetermined trajectory and allows the system to perform computed tomosynthesis examinations of a patient. In addition, the x-ray source is attachable/detachable from the system’s robotic arm, with the system compensating automatically for the change in weight at the robotic arm’s end due to removal of the x-ray source.

Abstract: A method for geometric calibration of a volume imaging apparatus disposes calibration phantom in a radiation path that includes a subject positioned between an x-ray source and a detector. The phantom has a number of radio-opaque markers formed of a marker material. In a repeated sequence, at each of a number of positional relationships of the x-ray source to the detector: 2D projection image data is acquired for the subject and the phantom, wherein the 2D projection image data distinguishes at least first and second x-ray energy distributions; source-to-detector geometry of the imaging apparatus is calculated, corresponding to the acquired 2D projection image data for the first and second x-ray energy distributions. The method reconstructs and displays a 3D volume image of the subject according to acquired anatomy image data from the subject and source-to-detector geometry within the 2D projection images.

Abstract: The present invention provides an intraoral X-ray system comprising:



an X-ray source located in an environment;
a robotic arm comprising an actuatable scissor arm, the robotic arm having a first end configured to be attached to a mounting and a second end attached to the X-ray source, at least one of the first and the second ends comprising a rotatable actuatable joint;
a position sensor to determine variation of position and/or orientation of the environment with respect to the X-ray source and variation of position and/or orientation of a mobile X-ray sensor with respect to the X-ray source; and
a driving unit actuating the robotic arm as a function of the determined variation of position and/or orientation to control the position and/or orientation of the X-ray source with respect to a predetermined position and/or orientation of the X-ray source.
