(EN) MOBILITY OF AN X-RAY IMAGING SYSTEM

Abstract
(EN) The present invention relates to the mobility of an X-ray system. In order to provide X-ray imaging systems with improved mobility, a base (10) for a mobile X-ray imaging system is provided that comprises a carriage (12), a mounting structure (14) mounted to the carriage and a wheel base (16) with a wheel arrangement (18) of at least three wheels (20) mounted to the carriage. The mounting structure is configured to movably hold an X-ray imaging device. The carriage comprises a first end portion (22) and an opposite second end portion (24). The first end portion is configured as a front end arrangeable closer to an object during X-ray imaging, and the second end portion is configured as a rear end arrangeable away from an object during X-ray imaging. The at least three wheels are each mounted to the carriage to be pivotable around a vertical pivot axis (26) and to rotate around a horizontal wheel axis (28), At least two of the at least three wheels are forming rearside wheels (20RW) mounted in the region of the rear end; and at least one of the at least three wheels is forming a frontside wheel (20FW) mounted in the region of the front end. The rearside wheels are independently actively steerable in their orientation around the vertical pivot axis by a pivot actuator. At least one of the wheels is actively drivable around its horizontal axis by a drive actuator to move the mobile base in relation to a floor.
