A medical imaging system includes a movable station having a C-arm, a collector, an X-ray beam emitter, and a controller. The collector is attached to a first end of the C-arm. The X-ray beam emitter faces the collector to emit an X-ray beam in a direction of the collector and is attached to a second end of the C-arm. The controller moves one of the X-ray beam emitter and the collector to a first offset position along a lateral axis orthogonal to the arc, and obtains a first set of images by rotating the collector and the X-ray beam emitter along the arc about a scanned volume. The controller moves the one of the X-ray beam emitter and the collector to a second offset position along the lateral axis, and obtains a second set of images. The controller combines the first and second set of images to generate a three-dimensional image of the scanned volume.

Examples of the present disclosure describe systems and methods for using gesture recognition to control medical hardware and software. In aspects, an activation signal may be received by an input processing system, such as a gesture recognition system, a voice recognition system, or a touch-based system. After receiving the activation signal, user input may be received by the input processing system. The user input may be processed to determine a current or applicable context. Based on the context, one or more actions corresponding to the user input may be identified. The input processing system may then cause the identified action(s) to be performed.

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.

The present disclosure is related to systems and methods for controlling a patient bed of a medical device.
