Abstract: When a control unit 30 detects that the apparatus becomes a traveling mode, the control unit 30 stops the power supply from a power supply circuit 52 to an opening-degree sensor S2 of a collimator leaf and a distance sensor S3 for detecting the distance between an X-ray tube 11 and a subject. On the other hand, for an acceleration sensor S1 for measuring the acceleration of a collimator 12, power supply from the power supply circuit 52 is stopped. When the control unit 30 determines that the apparatus is not in the traveling mode, electric power is supplied to all of the acceleration sensor S1, the opening-degree sensor S2, and the distance sensor S3. As a result, power consumption can be reduced by constantly supplying electric power to the acceleration sensor S1 required to perform constant monitoring, and in the traveling mode, power supply to the opening-degree sensor S2 and the distance sensor S3 used when performing X-ray imaging is stopped, so that power consumption can be reduced.

Abstract: A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.

Abstract: A method and device for acquiring a radiological image of at least part of a patient placed in a gantry. The method includes emitting radiation from a source that passes through the at least part of the patient and receiving the radiation at a detector. In one embodiment the detector may include a single flat panel sensor having a radiation sensitive surface and operable in at least a flat panel mode and a linear sensor mode. The method also rotating the source and the detector around at least a part of the patient and moving the detector along guides of a panel motion system along an axis perpendicular to the central axis of propagation. Also, the method includes translating the source and the detector in a direction of movement substantially perpendicular to the central axis of propagation.

Abstract: 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 reconstructed the patient's maxillofacial first region of interest (ROI1), —displaying the reconstructed axial CBCT slice of the patient's 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).

Abstract: Described are anatomically specified conformation computed tomography (ASC-CT) systems, which are fully tomographic x-ray imaging systems configured to conform to the contour of the anatomy of interest and perform a near scatter-free image acquisition, thereby providing an enhanced contrast resolution in the reconstructed CT image volume. The apparatus comprises independently controlled, yet synchronized, x-ray generation and detection assemblies configured to perform a tomographic image acquisition. The method of image acquisition entails adjusting the layout of the x-ray panels within the detector assembly based on the shape of the anatomy, followed by capturing a collimated, narrow x-ray beam composed of primary photons while sweeping a circular trajectory around the anatomy placed in the field of view, resulting in a conforming sinogram of the anatomy.
