The invention concerns a method for obtaining operating parameters for x-ray imaging a patients maxillofacial region, the method comprising: &#x2014;identifying a patients maxillofacial first region of interest ROI, &#x2014;determining a height of a horizontal plane of said patients maxillofacial first region of interest ROIwhen the patient is in an occlusion position or bites a patient positioning accessory, said horizontal plane passing through the teeth and the bones of the jaw, &#x2014;acquiring through a slit-shaped collimator window a first set of data relative to said patients maxillofacial first region of interest ROIincluding the horizontal plane using x-ray CBCT imaging and a first x-ray dose, said first set of data being suitable for generating a CBCT slice, &#x2014;reconstructing the CBCT slice comprising the horizontal plane based on the first set of data relative to the patients maxillofacial first region of interest ROI, &#x2014;obtaining operating parameters for an x-ray imaging apparatus based on the reconstructed CBCT slice in view of acquiring a second set of data of a patients maxillofacial second region of interest ROIusing a second x-ray dose, the first x-ray dose being lower than the second x-ray dose.

Method and a system for obtaining operating parameters for x ray data acquisition

The invention concerns a method for obtaining operating parameters for an x-ray CBCT imaging apparatus in view of acquiring a set of data of a patient's maxillofacial region. The method comprises: identifying a patient's maxillofacial first region of interest (ROI1), determining a height of a horizontal plane of said patient's maxillofacial first region of interest (ROI1) when the patient is in an occlusion position or bites a patient positioning accessory, acquiring through a slit-shaped collimator window a first set of data relative to said patient's maxillofacial first region of interest (ROI1) including the horizontal plane using x-ray CBCT imaging, reconstructing an axial CBCT slice comprising the horizontal plane based on the first set of data relative to the patient's maxillofacial first region of interest (ROI1), displaying the reconstructed axial CBCT slice of the patients maxillofacial first region of interest (ROI1) from the acquired first set of data, defining at least partially a second region of interest (ROI2) based on the displayed reconstructed axial CBCT slice of the patient's maxillofacial first region of interest (ROI1) and intersecting the latter, obtaining operating parameters for an x-ray CBCT imaging apparatus based on at least the defined second region of interest (ROI2) in view of acquiring a second set of data including the defined second region of interest (ROI2).

Method and system for obtaining operating parameters for 3D x ray acquisition

Certain exemplary method and/or apparatus embodiments herein can include&#x2014;a support frame, &#x2014;a movable gantry that supports an x-ray source and an x-ray sensor in correspondence with the x-ray source and that is movable relative to the support frame, &#x2014;a patient positioning accessory support member configured to support a patient positioning accessory of a specific type that is adapted to be used in the apparatus for conducting a specific examination on a patient, where the patient positioning accessory comprises at least one passive identification element that identifies the specific type of the patient positioning accessory, and the apparatus further comprises an active identification system that is configured to cooperate with the at least one passive identification element of the patient positioning accessory in order to identify the specific type of the patient positioning accessory.

Extra oral dental imaging apparatus with patient positioning accessory detection

The invention concerns a dental imaging apparatus comprising: &#x2014;a support frame, &#x2014;a movable gantry that comprises two opposite arms respectively supporting an x-ray source and an x-ray sensor facing the x-ray source, &#x2014;a movable patient positioning arm connected to the support frame, &#x2014;two cameras positioned on the gantry arm supporting the x-ray source and on the positioning arm so as to respectively acquire side and front images of a patient's head, &#x2014;a display assembly configured to simultaneously display in real time a side image and a front image of the patient's head taken by the two cameras.
