In a sensor system for an actuator, in particular a lifting column, a force sensor is configured to detect a total force acting on an actuator part. An acceleration sensor is configured to detect an acceleration of the actuator part. Accordingly, the sensor system has a processing device, which is configured to control a drive of the actuator for moving the actuator part on a basis of the detected total force and the detected acceleration.

The present disclosure relates to methods and systems for calibrating an X-ray apparatus. The X-ray apparatus may include an X-ray detector and a collimator. To calibrate the X-ray apparatus, the methods and systems may include moving the X-ray detector from a first position to a second position along a first axis of a coordinate system, wherein the first position is under a scanning table, and the second position is outside the scanning table; moving the collimator to align the collimator with the X-ray detector at the second position; determining one or more parameters; and determining a second value of the first encoder when the collimator is aligned with the X-ray detector at the first position based on the one or more parameters.

The present disclosure relates to a lifting apparatus. The lifting apparatus may include a base column, a mobile column, a sliding component, a supporting arm, a lifting system, and a move-coordination system. The mobile column connected to the base column may be vertically movable relative to the base column. The lifting system may be configured to cause the movement of the mobile column. The sliding component connected to the mobile column may be vertically movable relative to the mobile column. The mobile column and the sliding component may be connected via the move-coordination system, which enables the sliding component and the mobile column to move simultaneously according to a predetermined relative motion relationship. The supporting arm may be connected to the sliding component.

This X-ray fluoroscopic imaging apparatus includes a first arm, a second arm, and a controller. The controller is configured to move a second base to move the second arm to a position where the second arm does not interfere with the first arm when the first arm and the second arm interfere with each other and change the angle of the second arm so that the angle of the second arm becomes a predetermined imaging angle to arrange the first arm and the second arm at positions where the first arm and the second arm do not interfere with each other to perform imaging.

A method for controlling the movement of an X-ray source via a suspension device includes obtaining, during a movement of the suspension device along the rail, a first speed of the suspension device at the first reference point. The first reference point may correspond to a first target position. The method may also include determining whether the first speed of the suspension device at the first reference point is less than a threshold speed. In response to a result of the determination that the first speed of the suspension device at the first reference point is less than the threshold speed, the method may further include actuating a control device to move the suspension device to the first target position.

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.

Disclosed is a linear array ultra-fast scanning x-ray imaging device. The linear array x-ray imaging device is single photon sensitive, operating in frame output mode and including a pixel array Application Specific Integrated Circuit including the readout pixel array. The ASIC includes digital control logic and sufficient memory to accumulate digital output frames in various modes of operation prior to output from the ASIC, permitting advanced imaging functionalities directly on the ASIC, while maintaining a dynamic range of 16 bits and single photon sensitivity. The effective or secondary frames output from the pixel array ASIC can be tagged with user provided external triggers synchronizing the effective frames to the x-ray beam energy and/or to the movement of the x-ray source or imaged object. This enables dual energy imaging and ultra-fast scanning, without complex and costly conventional photon counting x-ray imaging sensors. The system architecture is simpler and higher performance.
