An apparatus and method for use in medical imaging simulate within an imaging coil normal movements of body parts such as joints, and improve imaging of soft tissue and bony parts as compared to a static system in which images are taken of a joint in only one position. A joint or body parts is moved into various positions in multiple planes within its range of motion while a series of images are taken of the joint in the different positions. The images are collated into a cine format to effectively show the joint in motion. A surface or volume coil may be coupled for movement with the joint or body part and maintained in the proper spatial relationship with the primary coil's electromagnetic field. The systems may be provided as mechanisms usable with existing imaging tables to reduce cost, or may be built into a new imaging table. It is possible to use a larger primary coil, allowing increased range of movement. Traction may be applied to a joint being imaged, in order to load the joint.
