摘要：
An X-ray system includes an X-ray source and/or an X-ray detector, at least two guide rails, and at least one carriage on which the X-ray source and/or the X-ray detector is mounted. The carriage includes first guide wheels and second guide wheels, and a drive unit attached to the carriage. The drive unit includes one or more drive wheels and a motor drive that drives the one or more drive wheels. The first guide wheels are adjustably mounted on the carriage and move between at least two different positions relative to the carriage. In a first position, the first guide wheels rest on the guide rails while the drive wheels are in a lifted position relative to the guide rails and do not engage with the guide rails such that the carriage is moveably mounted on the guide rails via the first and second guide wheels. In a second position, the first guide wheels disengage from the guide rails while the drive wheels engage with the guide rails to establish a frictional connection with the guide rails such that the carriage is moveably mounted on the guide rails via the second guide wheels and the drive wheels.
