Motion controllers for mobile x-ray devices

A method for moving a mobile X-ray device, the method comprising:

• providing the mobile X-ray device having:
• (1) an equipment cart that has wheels and a lifting device, (2) a support assembly arranged on the lifting device, (3) a C-arm mounted on the support assembly so as to be displaceable along a circumference of the support assembly, wherein the C-arm has an X-ray source and an X-ray receiver arranged opposite the X-ray source, and (4) a motion controller;
• controlling a movement of the C-arm, by the motion controller, such that a central axis extending between the X-ray source and the X-ray receiver is fixed in space for any given pose of the C-arm.

A non-transitory electronically readable storage medium including a computer program that when executed, the non-transitory electronically readable storage medium and computer program configured to cause a computing device to perform:

• control a movement of a C-arm of a mobile X-ray device having (1) an equipment cart that has wheels and a lifting device, (2) a support assembly arranged on the lifting device, and (3) the C-arm mounted on the support assembly so as to be displaceable along a circumference of the support assembly, wherein the C-arm has an X-ray source and an X-ray receiver arranged opposite the X-ray source, such that a central axis extending between the X-ray source and the X-ray receiver is fixed in space for any given pose of the C-arm.
