Disclosed is a digital breast tomosynthesis system including: an X-ray tube configured to generate X-rays; a C-arm configured to receive the X-ray tube and rotate about a first rotation axis during an X-ray exposure period; an X-ray detector configured to convert the X-ray, which is emitted from the X-ray tube and passes through a breast, into image information; and a focal spot controller configured to operate in conjunction with a movement of the X-ray tube caused by a rotation of the C-arm, in which the focal spot controller controls a position of a focal spot of the X-ray with various methods. As a result, the position of the focal spot of the X-ray tube may be controlled by the simple structure and method, thereby eliminating blurring of a projection image that affects the determination of quality of a three-dimensional image, and thus significantly improving sharpness.

According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a detector, and processing circuitry. The X-ray tube emits X-rays. The detector detects X-rays that have been emitted from the X-ray tube and have passed through the subject. The processing circuitry sets an imaging condition. The processing circuitry evaluates the imaging condition based on information on a lower limit range of a count value of the detected X-rays that may cause image degradation.

A system can have an x-ray source that generates a series of individual x-ray pulses for multi-energy imaging. A first x-ray pulse can have a first energy level and a subsequent second x-ray pulse in the series can have a second energy level different from the first energy level. An x-ray imager can receive the x-rays from the x-ray source and can detect the received x-rays for image generation. A generator interface box (GIB) controls the x-ray source to provide the series of individual x-ray pulses and synchronizes detection by the x-ray imager with generation of the individual x-ray pulses. The GIB can control x-ray pulse generation and synchronization to optimize image generation while minimizing unnecessary x-ray irradiation.

Various methods and systems are provided for medical imaging systems. In one example, an imaging system comprises: a C-shaped gantry; an x-ray tube coupled to a first end of the C-shaped gantry; an x-ray detector coupled to a second end of the C-shaped gantry, opposite to the x-ray tube; and a controller with computer readable instructions stored on non-transitory memory that when executed, cause the controller to: identify a reference image; determine a target electrical current based on the reference image; determine a corrected electrical current based on the target electrical current; and transition an electrical current provided to the x-ray tube to the target electrical current by commanding the electrical current to the corrected electrical current while maintaining a constant voltage provided to the x-ray tube.
