An X-ray diagnosis apparatus according to an embodiment includes processing circuitry configured: to acquire a two-dimensional X-ray image of an examined subject imaged in a first imaging process; to designate at least one track on which an X-ray generator is to move in a second imaging process to be performed after the first imaging process; and to perform a predicting process of predicting, on the basis of the two-dimensional X-ray image and the track, an artifact that is to occur when the second imaging process is performed by using the track.

An x-ray imaging apparatus and associated methods are provided to execute multi-pass imaging scans for improved quality and workflow. An imaging scan can be segmented into multiple passes that are faster than the full imaging scan. Data received by an initial scan pass can be utilized early in the workflow and of sufficient quality for treatment setup, including while the another scan pass is executed to generate data needed for higher quality images, which may be needed for treatment planning. In one embodiment, a data acquisition and reconstruction technique is used when the detector is offset in the channel and/or axial direction for a large FOV during multiple passes.

A method may include obtaining a feedback or a reference value of a tube voltage applied to a radiation source of a radiation device for generating radiation rays. The method may also include determining, based on the feedback or the reference value of the tube voltage, a specific value of a focusing parameter associated with a focusing device of the radiation device. The method may further include causing the focusing device to shape a focus of the radiation rays according to the determined value of the focusing parameter. The focus of the radiation rays may satisfy an operational constraint under the specific value of the focusing parameter.

An x-ray imaging apparatus and associated methods are provided to receive measured projection data in a primary region and measured scatter data in asymmetrical shadow regions and determine an estimated scatter in the primary region based on the measured scatter data in the shadow region(s). The asymmetric shadow regions can be controlled by adjusting the position of the beam aperture center on the readout area of the detector. Penumbra data may also be used to estimate scatter in the primary region.

An X-ray imaging system using multiple pulsed X-ray sources to perform highly efficient and ultrafast 3D radiography is presented. There are multiple pulsed X-ray sources mounted on a structure in motion to form an array of sources. The multiple X-ray sources move simultaneously relative to an object on a pre-defined arc track at a constant speed as a group. Electron beam inside each individual X-ray tube is deflected by magnetic or electrical field to move focal spot a small distance. When focal spot of an X-ray tube beam has a speed that is equal to group speed but with opposite moving direction, the X-ray source and X-ray flat panel detector are activated through an external exposure control unit so that source tube stay momentarily standstill equivalently. 3D scan can cover much wider sweep angle in much shorter time and image analysis can also be done in real-time.

A surgical frame incorporating an electromagnetic-radiation imaging device, and a radiation-mitigation system for use with the surgical frame are provided. The surgical frame can be capable of reconfiguration before, during, or after surgery, and can include a main beam that can be rotated, raised/lowered, and tilted upwardly/downwardly to afford positioning and repositioning of a patient supported thereon. The surgical frame can support the electromagnetic-radiation imaging device. One of an emitter and a receiver of the electromagnetic-radiation imaging device can be positioned under the main beam of the surgical frame, and the other of the emitter and the receiver of the electromagnetic-radiation imaging device can be positioned over the main beam of the surgical frame. The radiation-mitigation system can serve to intercept/block and mitigate at least some of the scatter of the electromagnetic radiation from the emitter.

The present disclosure discloses a scanning method and apparatus, a storage medium, and a computer device. The method includes: obtaining plain film information of a target scanning object, and determining a target bed height based on the plain film information; adjusting the plain film information based on the target bed height to obtain target plain film information; and performing a subsequent operation based on the target plain film information. The present disclosure helps to quickly determine the target bed height, adjust the plain film information based on the target bed height, and perform the subsequent operation based on adjusted plain film information. Thus, a quality of a scanned image is improved while an adjustment efficiency is increased, thereby greatly improving user experience.

A system and method for improved image acquisition of multiple pulsed X-ray source-in-motion tomosynthesis imaging apparatus by generating the electrocardiogram (ECG) waveform data using an ECG device. Once a representative cardiac cycle is determined, system will acquire images only at rest period of heart beat. Real time ECG waveform is used as ECG synchronization for image improvement. The imaging apparatus avoids ECG peak pulse for better chest, lung and breast imaging under influence of cardiac periodical motion. As a result, smoother data acquisition, much higher data quality can be achieved. The multiple pulsed X-ray source-in-motion tomosynthesis machine is with distributed multiple X-ray sources that is spanned at wide scan angle. At rest period of one heartbeat, multiple X-ray exposures are acquired from X-ray sources at different angles. The machine itself has capability to acquire as many as 60 actual projection images within about two seconds.
