摘要： An apparatus for computed tomography imaging of a patient has a rotatable mount that is actuable to rotate about a rotation axis and that supports, at opposite ends an x-ray source and an x-ray detector, wherein the x-ray source is disposed to direct a radiation beam through the patient and toward the detector. A patient positioning apparatus positions the patient relative to the rotation axis. A control logic processor controls rotation of the rotatable mount and acquires image data for the patient at each of a number of angular positions about the rotation axis. A collimator is disposed in front of the x-ray source and controlled by the control logic processor to center the radiation beam, at each of the plurality of angular positions, on a region of interest that is spaced apart from the rotation axis.

摘要： An extra-oral dental imaging system comprises an X-ray source (102) and an imaging device (101) suitable for producing multiple frames during at least part of an exposure of an object (200), the imaging device (101) being displaced along a scanning direction (X). A method for creating a cephalometric image of a human skull comprises a step of setting said imaging device (101) with an active area having in an imaging plane a width extending along said scanning direction (X), said width varying along a height direction perpendicular to said scanning direction (X); a step of synchronously displacing the X-ray source (102) and the imaging device (101) along said exposure profile; and a step of registering multiple frames produced by the imaging device (101) during the exposure of said object (200) to be imaged. Using for creating a cephalometric image by digital tomosynthesis.

摘要： A dental X-ray apparatus of the conical-beam digitized-tomography type includes: an X-ray generator emitting an X-ray beam towards an object and provided with a collimation element for collimating the emitted beam; an X-ray sensor having an active surface arranged opposite the generator; wherein the generator and the sensor can rotate simultaneously about a rotation axis, the sensor being oriented so that a longitudinal axis extending from the generator to the sensor through the rotation axis is perpendicular to the active surface of the sensor, the center of the sensor being transversally offset relative to the projection of the axis on the sensor's active surface, the arrangement of the collimation element and the sensor thus offset defining that the collimated beam illuminates the sensor's active surface while leaving a peripheral area of the surface that is faintly illuminated by the collimated beam relative to the rest of the active surface.
