Abstract: An accessory kit is provided for interventional procedures using a magnetic resonance imaging scanner. The accessory kit includes a patient support and an electrical connection adapter. The patient support has a first end proximal and a second end distal to the scanner. The distal end is configured to create a space to accommodate a clinician, such as narrowing of the distal end or at least one cutout on a side of the distal end. The electrical connection adapter interfaces with the scanner and a scanner table. The accessory kit is configured so that when the proximal end is extended into the scanner bore, the distal end extends outside the bore. The narrowed width and/or cutout(s) of the exposed distal end and the extended gap between the scanner and scanner table create space on at least one side of the patient support that a clinician may use to access a patient.

Abstract: A medical apparatus, includes a medical instrument with an acquisition unit for a magnetic resonance signal, the acquisition unit exhibiting a non-constant sensitivity profile in the azimuthal direction relative to an axis of the medical instrument. An azimuthal orientation of the medical apparatus is determined by an evaluation unit from magnetic resonance signals received by the acquisition unit.

Abstract: In a method and apparatus for interventional imaging in magnetic resonance tomography, a contrast agent liquid is prepared by saturation or excitation of the nuclear spins therein, such that it shows with a poor signal in the vessel system of a patient to be examined after injection, or the stationary tissue is prepared by saturation or excitation of the nuclear spins therein such that the contrast agent liquid shows with strong signal (compared to the tissue) in the vessel system of a patient to be examined after injection.

Abstract: Systems, methodologies, media, and other embodiments associated with facilitating intra-procedurally determining the position of an internal anatomical target location using an externally measurable parameter are described. One exemplary method embodiment includes pre-procedurally correlating internal anatomy motion with external marker motion. The example method may also include providing computer graphics to an augmented reality system during a percutaneous procedure to facilitate image guiding an interventional device with respect to the internal anatomy.

Abstract: A method of automatically adjusting at least one MR image parameter for an interventional procedure includes adaptively tracking an MR micro-coil catheter and automatically updating an imaging scan plane's position and orientation, as well as other features including, but not limited to, field-of-view, resolution, temporal resolution, slice thickness, tip angle, and TE. The disclosed system provides a more natural interface for a physician operating the MR scanner during an interventional procedure. The scanner can react to changes in the clinical environment and automatically adjust a number of image parameters. For example, during catheter insertion, images are acquired at lower resolutions, and possibly larger fields of view, to help facilitate faster updates and tracking. Once the catheter reaches a target area in the tissue and its motion slows, an MR image of higher resolution, and possibly lower field of view, is acquired.
