Abstract

The present application relates to a motion guiding assembly for guiding the motion of a collimator device. The motion guiding assembly may include a first pair of flexible plates connected to the collimator device. The first pair of flexible plates may be deformed in a direction perpendicular to the opening of the collimator device. Based on the driving force, the deformation of the first pair offlexible plates can guide the motion of the collimator device.

Description

technical field [0001] The present application relates generally to a mechanical device and, more particularly, to a motion guide assembly for guiding the motion of a collimator device. Background technique [0002] Radiation systems (eg, computed tomography (CT) scanners, radiation therapy devices) may include collimation components to reduce harmful radiation emitted from radiation sources. Application-specific adjustments for radiation reduction can be achieved through physical movement of the collimator device within the collimation assembly. The motion of the collimator device may be driven and / or guided by a motion system. However, traditional motion systems often exhibit unanticipated constraints, resulting in unpredictable behavior due to changes in friction over the system's lifetime. Accordingly, it would be desirable to develop a frictionless motion guiding assembly to guide the motion of a collimator device. Contents of the invention [0003] An aspect of th...
