CT imaging apparatus
A dental or medical CT imaging apparatus including a first longitudinally extending frame part. A support, construction extends substantially perpendicularly from the longitudinally extending frame part. An X-ray source and an image detector which together form an X-ray imaging assembly are mounted to the support construction. A first driving mechanism is provided to move the X-ray imaging assembly about a virtual or physical rotation axis. A control system having at least one operation mode that simultaneously controls the first driving mechanism and the X-ray imaging assembly is provided. The support construction includes at least one guiding mechanism configured to enable laterally moving at least one of the X-ray source and the image detector in relation to the support construction. A range of the lateral movement of at least one of the X-ray source and the image detector includes a base position and a first and a second extreme position.
Medical image diagnosis apparatus and controlling method
A medical image diagnosis apparatus according to an embodiment of the present disclosure includes: a gantry, one or more columns, a processing circuitry, and, and a supporting and moving mechanism. The gantry includes an imaging system related to imaging a patient. The one or more columns are each configured to support the gantry so as to be movable in a vertical direction. The processing circuitry generates an image on the basis of an output from the imaging system. The supporting and moving mechanism is configured to support the patient from underneath, while being installed so as to be movable in a direction intersecting the moving direction of the gantry. The processing circuitry controls the moving of the supporting and moving mechanism.
POSITIONING OF A MOBILE X-RAY DETECTOR
A positioning device for a mobile x-ray detector, an x-ray device containing such a mobile positioning device, and a method mutually align a mobile x-ray detector and an x-ray emitter in relation to one another. In order to enable exact mutual alignment or positioning of the mobile x-ray detector in relation to the x-ray emitter, a positioning device is used for a mobile x-ray detector. The positioning device contains at least one marker and/or at least one sensor for determining the position and/or the orientation of the positioning device and contains a number of connection elements for establishing a mechanical connection between the positioning device and the mobile x-ray detector.
SYSTEMS AND METHODS FOR CONTROLLING MOTION OF DETECTORS HAVING MOVING DETECTOR HEADS
An imaging system is provided that includes a gantry, at least five detector units mounted to the gantry, a corresponding collimator for each of the detector units, at least one processing unit, and a controller. Each collimator has septa defining plural bores for each pixel of at least some of a plurality of pixels of the detector unit. A corresponding interior septum of the collimator is disposed above an internal portion of a corresponding pixel of the at least some of the plurality of pixels. The at least one processing unit is configured to obtain object information corresponding to the object to be imaged. The controller is configured to control an independent rotational movement of each the detector units used to acquire scanning information by detecting emissions from the object, wherein the controller rotates each of the detector units at a corresponding sweep rate.
DEVICE FOR SUSPENDING AN X-RAY GRID, ARRANGEMENT WITH AN X-RAY GRID AND METHOD FOR OPERATING AN X-RAY GRID
A device for suspending an x-ray grid has a first rotating frame which can be rotated about a first axis. The x-ray grid is disposed in or on the rotating frame. Two first flexible hinge elements are connected to the first rotating frame and are aligned along the first axis. The first rotating frame is reversibly rotatable about the first axis. An x-ray arrangement has one or more such suspension devices between an x-ray emitter and an x-ray detector. The articulated flexible elements of the novel device are completely play-free and significantly more cost-effective that separate hinges.
POSITIONING OF AN EXAMINATION OBJECT FOR AN IMAGING METHOD
A method is described for positioning of an examination object for an imaging method. The method is used to record an external image of externally visible features of the examination object. The recording of the external image is used as the basis for determining a position and/or orientation of at least one part of the examination object assigned to the imaged features. Subsequently, a check is performed as to whether the determined position and/or orientation of the at least one part of the examination object conforms to a reference position and/or reference orientation. Finally, if the determined position and/or orientation of the at least one part of the examination object does not conform to the reference position and/or reference orientation, the position and/or orientation of the at least one part of the examination object is corrected. Also described is an object-positioning facility. Furthermore, an imaging medical facility is described.
SCANNABLE OPTICAL IDENTIFIER FOR USE WITH IMPLANTABLE MEDICAL DEVICES
Apparatus for identifying a patient, said apparatus comprising: a medical device for implantation into the patient; an optical identifier affixed to the device; wherein at least a portion of the optical identifier is radiopaque, whereby to generate a scannable X-ray image of the optical identifier when the medical device is imaged using X-ray.
SCANNING DIGITAL FLUOROSCOPE
A system for taking fluoroscopic images of large animals having a rotatable plate with a plurality of detectors disposed on the rotatable plate, wherein the detectors are arranged as spokes extending radially outwardly from a central rotational point on the rotatable plate with collimators disposed on the side edges of the spokes. A drive assembly rotates the plate about an axis extending through the central rotational point at a speed such that the duration of successive image frames corresponds to the time taken for each spoke of detectors to move to the position of an adjacent spoke of detectors.
MEDICAL IMAGING DEVICE AND SUSPENSION GANTRY THEREOF
The present disclosure discloses medical imaging devices and suspension gantries thereof. An example medical imaging device includes a suspension gantry and a rotatable C-arm which is connected with the suspension gantry and provided with an imaging chain. The suspension gantry includes a suspension base, a first rotating arm configured to be connected to the suspension base and rotatable around a first axis, and a second rotating arm configured to be connected to the first rotating arm and rotatable around a second axis. The rotatable C-arm is configured to be connected with the second rotating arm and be rotated around a third axis.
Method, device, and computer program product for capturing projection images with optimized movement path
A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.
