An x-ray system and method can improve speed of imaging and/or reduce radiation dosage compared to conventional imaging technique, such as CT. The system can identify a volume of interest within a subject. The system can include scatter removal algorithms and/or a beam selection device. Material decomposition of the imaged subject can be based on the dual energy decomposition method which can be iterative to solve the energy response function equation system.

A device and methods for performing a simulated CT biopsy on a region of interest on a patient. The device comprises a gantry (22) configured to mount an x-ray emitter (24) and CT detector (26) on opposing sides of the gantry, a motor (28) rotatably coupled to the gantry such that the gantry rotates horizontally about the region of interest, and a high resolution x-ray detector (172) positioned adjacent the CT detector in between the CT detector and the x-ray emitter.

The method comprises receiving an image sequence of the subject from the camera during the medical imaging scan; receiving at least one of the current position or velocity of the patient table during the medical imaging scan; performing a motion tracking analysis of the image sequence to extract a motion model, wherein at least one of the motion tracking analysis or the motion model is tailored to the body region of interest and takes into account the at least one of the current patient table position or velocity; and analysing the motion model to detect subject motion and, if the detected motion is above a threshold, at least one of adapting the medical imaging examination or issuing an alert.

A panoramic X-ray imaging apparatus includes: an X-ray generating unit; an X-ray detecting unit; a support that supports the X-ray generating unit and the X-ray detecting unit; a drive mechanism that turns at least the X-ray generating unit and the X-ray detecting unit by driving the support; a displacement mechanism that adds movement including a displacement component in a direction different from the turning to the X-ray detecting unit; a subject holding unit that holds an imaging subject; a turning controller that controls the turning by a drive mechanism and the displacement mechanism. The turning controller controls the drive mechanism and the displacement mechanism so as to add the movement avoiding the contact with the shoulder of the imaging subject during the turning of the X-ray generating unit and the X-ray detecting unit by the drive mechanism during the panoramic X-ray imaging.

A C-arm X-ray apparatus includes an x-ray emitter (5) and an X-ray detector (4) which are maintained on a C-arm (2) mounted on a reference plane. The x-ray emitter (5) has nanorods as electron emitters and has an elongated structure which is at least partially aligned along a surface normal of the reference plane.

Disclosed herein is an apparatus comprising: a first radiation source configured to produce a first divergent radiation beam toward an object; a second radiation source configured to produce a second divergent radiation beam toward the object; and an image sensor; wherein the object is configured to rotate with respect to the image sensor, the first radiation source, and the second radiation source, and wherein relative positions among the image sensor, the first radiation source, and the second radiation source are fixed.

A CT scanning method compensates gantry motion blurring in projection measurement based on synchronized focal spot movement and detector data shifting. Tube power is increased by moving the focal on the target and reducing focal spot dwell duration. The CT scanning method is used on helical CT and cone beam with a rotating anode source and CBCT and TBCT with a linear array x-ray source.

A method for controlling an FFS X-ray system comprises: simulating a beam geometry of the X-ray beam at a specified FFS deflection onto the detector during recording of a projection image; determining whether cross-radiation is present in a region around the detector by the simulated beam geometry of the X-ray beam; generating FFS control data for the recording of the projection image, wherein the FFS control data either (i) causes FFS deflection that is reduced relative to the specified FFS deflection for the recording of the projection image in the event of the cross-radiation being present for the recording of the projection image or (ii) causes the specified FFS deflection otherwise; repeating the simulating, the determining and the generating FFS control data for at least one further recording of a projection image; and generating a control data set including the FFS control data, for controlling an FFS X-ray system.

A radiographic control apparatus includes an obtaining unit configured to obtain position information about a transmission unit configured to transmit a radio wave based on a radio field intensity of the transmission unit and position information about a reception unit configured to receive the radio wave, the transmission unit being disposed on a radiographic apparatus configured to generate a radiographic image of a subject based on radiation emitted from a radiation generation apparatus, and a correction unit configured to correct the position information about the transmission unit using depth information about an area to which the radiographic apparatus belongs in an optical image captured by an imaging apparatus, the depth information being obtained from the optical image.

A system and method are provided for medical imaging that includes acquiring, during a common imaging acquisition process, rotational, x-ray volume image data and x-ray tomosynthesis image data from a subject. The method includes reconstructing a time-resolved three-dimensional (3D) image volume from the rotational, x-ray volume image data and producing a four-dimensional (4D) image series of the subject with resolved overlapping features by selectively combining the time-resolved 3D image volume and the x-ray tomosynthesis imaging data.
