Abstract
Example devices, apparatus, and methods concern intervention-independent imaging control for an MRI system. A hand wearable device (e.g., glove) that can be manipulated independently of an interventional device (e.g., catheter) in use to treat a patient transmits position signals describing an orientation of the device to an MRI system. The device may have fiducial markers mounted on an operator's fingers. The MRI system determines a desired scan plane that will correspond to the orientation of the intervention-independent device and performs a diagnostic scan on the desired scan plane. The spatial proximities of the markers may control a switch based control that controls image acquisition parameters including field of view.
