Provided in the present application are a C-arm imaging system and a tube assembly mounting method. The C-arm imaging system includes a C-arm, a tube assembly, a detector assembly, and a rotation assembly. The C-arm includes an inner surface and an outer surface disposed opposite to each other. The tube assembly is located at a first end of the C-arm, and is mounted on the inner surface of the C-arm. The detector assembly is located at a second end of the C-arm opposite to the first end. The rotation assembly is mounted on the outer surface of the C-arm. The C-arm is movable relative to the rotation assembly, and an outer surface opposite to an inner surface on which the tube assembly is located is slidable relative to the rotation assembly.

Real-time monitored computed tomography (CT) reconstruction for reducing a radiation does. During helical CT scanning of a target object, projections may be acquired in either a full mode which subjects the target object to a full radiation dose, or a reduced mode which subjects the target object to a reduced radiation dose (e.g., by reducing the number of projections acquired, reducing the exposure time, etc.). After a sector is acquired in the full mode, a slice of the target object that is influenced by that sector is identified, and a CT image of that slice is reconstructed using projections that have been previously acquired for that slice. When a stopping rule is satisfied based on this partial reconstruction, the full mode is switched to the reduced mode, and at least one subsequent sector is acquired in the reduced mode.

A radiographic imaging system includes a radiographic imaging apparatus, a control apparatus that controls radiographic imaging, and a notification unit. The radiographic imaging apparatus performs a first wireless communication with the control apparatus to transmit and receive images and a second wireless communication with the control apparatus to transmit and receive radio information to be used for the first wireless communication. The control apparatus causes the notification unit to provide different notifications such as the current state of the radiographic imaging apparatus or a state of a specific processing performed by the radiographic imaging apparatus.

A tube voltage control circuitry switches a tube voltage applied to an X-ray tube between a first tube voltage and a second tube voltage of lower value than the first tube voltage. A first signal generating circuitry generates a first switching signal at a first time interval. A view switching circuitry switches a view based on the first switch signal. A data acquisition circuitry performs data acquisition for each view via an X-ray detector. A second signal generating circuitry generates a second switch signal at a second time interval shorter than the first time interval. A gain switching circuitry switches gains of the data acquisition circuitry based on the second switch signal.

A system and method for the placement of a portable x-ray cassette is disclosed herein. In some embodiments, the system comprises a planar cassette element, a fabric, a collar element and a rigid sheet. The planar cassette element includes a hollow cavity disposed on a leading edge thereof and the fabric is configured to dispense from the hollow cavity, surround the planar cassette element and slide about the planar cassette element away from and toward the leading edge of the cassette element. The system allows for easy positioning of the portable x-ray cassette underneath a patient to be x-rayed.

Some embodiments of the present disclosure provide a pneumothorax detection method performed by a computing device. The method may comprise obtaining predicted pneumothorax information, predicted tube information, and a predicted spinal baseline with respect to an input image from a trained pneumothorax prediction model; determining at least one pneumothorax representative position for the predicted pneumothorax information and at least one tube representative position for the predicted tube information, in a prediction image in which the predicted pneumothorax information and the predicted tube information are displayed; dividing the prediction image into a first region and a second region by the predicted spinal baseline; and determining a region in which the at least one pneumothorax representative position and the at least one tube representative position exist among the first region and the second region.

A method for the artifact correction of three-dimensional volume image data of an object is disclosed. In an embodiment, the method includes receiving first volume image data via a first interface, the first volume image data being based on projection measurement data acquired via a computed tomography device, the computed tomography device including a system axis, and the first volume image data including an artifact including high-frequency first portions in a direction of a system axis and including second portions, being low-frequency relative to the high-frequency first portions, in a plane perpendicular to the system axis; ascertaining, via a computing unit, artifact-corrected second volume image data by applying a trained function to the first volume image data received; and outputting the artifact-corrected second volume image data via a second interface.

A method and apparatuses for a radiation detector apparatus, comprising a scintillator array comprising a plurality of scintillator crystals. The plurality of scintillator crystals includes a first scintillator crystal and a second scintillator crystal adjacent to the first scintillator crystal within the scintillator array. A photosensor array comprising a plurality of photosensors including a first photosensor configured to detect photons from the first scintillator crystal. A first separator positioned between the first scintillator crystal and the second scintillator crystal. First separator optically separates the first scintillator crystal and the second scintillator crystal such that the first photosensor detects photons from the first scintillator crystal and not from the second scintillator crystal.

In order to reduce a radiation dose delivered to an object or an observer, a facility for monitoring handling of the object has an optical unit configured to direct ionizing radiation onto the object and also a filter element in order to attenuate a part of the ionizing radiation. An imaging unit may detect portions of the ionizing radiation passing through the object in order to create an image of the object. A view acquisition system may acquire a viewing movement, and a control unit is configured, during a first operating mode, to control a position of the filter element as a function of the viewing movement. The control unit is configured to identify a predefined sequence of viewing movements and, as a function thereof, to switch into a second operating mode. The position of the filter element is controlled during the second operating mode as a function of an image analysis.
