Motion-based radiograph interlock systems, structures, and processes
09846131 · 2017-12-19 · ·

A motion-based interlock apparatus, system, and method prevent an x-ray source in an x-ray machine from activating if the current relative motion between the x-ray source and an image receptor would compromise the quality of the resulting plain radiograph. The system activates the interlock based on either or both of the velocity and acceleration of the tubehead, as measured by instrumentation corresponding to any of the tubehead, the extension arm, or off board the x-ray machine. The system may preferably compare the measured motion against one or more acceptable motion thresholds. If the measured motion exceeds one or more of the acceptable motion thresholds, exposure may preferably be delayed until the motion of the tubehead subsides. By ensuring that the image is not exposed while the tubehead is moving substantially, the quality of the resultant radiograph is improved.

Method, device, and computer program product for capturing projection images with optimized movement path

A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.

Multi-axis dynamic tracking for radiation therapy

A radiation device directs a beam of radiation onto a target. The beam can be adjusted using, for example, a control for setting beam shape and a control for setting beam intensity. The target is supported on a surface that can be adjusted using, for example, a control for setting surface position and a control for setting a speed for moving the surface. Controls are selected to adjust the beam and the surface cooperatively in order to compensate for movement of the target.

X-RAY MACHINES

The present disclosure provides an X-ray machine, which comprises a C-shaped arm. The C-shaped arm includes a connecting arm, a first support arm, and a second support arm. The first support arm and the second support arm are separately movably connected to the connecting arm. The first support arm moves relative to the connecting arm to move close to or away from the second support arm, and the connecting arm moves to drive the first support arm to move close to or away from the second support arm. An adjustable range of a distance between the first support arm and the second support arm is wider, so that when the radiation source is arranged on the second support arm and the detector is arranged on the first support arm, an adjustable range of a distance (SID) between the radiation source and the detector is wider.
