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: The invention relates to a positioning device for positioning a medical instrument relative to a patient, wherein the positioning device has a patient fastening member which is specified to fasten the positioning device to the patient, and has an instrument holder which is specified to hold the medical instrument, wherein the patient fastening member has a patient holding surface for bearing on the patient.

Abstract: The invention relates to a method for operating an imaging examination device (1), wherein signals are received from an object (5) to be examined and are identified and displayed in layers in the form of sectional images and/or three-dimensional images of the object (5), having the following steps: a) ascertaining a desired imaging layer (4) of the object (5) to be examined, b) determining the coordinates of a desired target point (6) in the desired imaging layer (4), c) determining the coordinates of a corrected target point (6?) while taking into consideration a distorted gradient field of the examination device (1) such that the examination device detects an imaging layer on which the desired target point (6) lies on the basis of the distorted gradient field while using the corrected target point (6?) instead of the desired target point (6), and d) detecting an imaging layer (4) by means of the examination device (1) using the corrected target point (6?) and visualizing an image obtained therefrom.

Abstract: The invention relates to a coil in the form of a transmitting and/or receiving coil of a device for wireless signal transmission by means of electromagnetic waves, wherein the coil has an impedance matching circuit for adapting the connection impedance of the coil to an input impedance of a signal transmitting and/or receiving device of the device for wireless signal transmission to be connected to the coil, wherein the impedance matching circuit is formed entirety or at least partially by at least partially overlapping conductor tracks of the coil. The invention also relates to a device for wireless signal transmission by means of electromagnetic waves, comprising a signal transmitting and/or receiving device and a coil connected to the signal transmitting and/or receiving device. The invention further relates to a method for producing such a coil.

Abstract: The invention relates to a hybrid system for performing a magnetic resonance tomography (MRT) and a radiofrequency ablation on a patient, comprising the following characteristics: a) the hybrid system comprises a magnetic resonance tomography system in which MRT high-frequency signals for carrying out the magnetic resonance tomography can be generated and supplied on an output terminal of the magnetic resonance tomography system; b) the hybrid system comprises at least one ablation electrode for performing the radiofrequency ablation; and c) the at least one ablation electrode is coupled to the output terminal of the magnetic resonance tomography system such that the radiofrequency ablation can be carried out by the at least one ablation electrode by means of the MRT high-frequency signals. The invention also relates to a method for operating such a hybrid system.

Abstract: The invention relates to an operative assistance system (1) for a magnetic resonance tomograph (I) for displaying an entry point (IX) for an instrument on the surface of a patient (VIII), comprising at least one device (3) having at least one first holder (IV) for accommodating at least one conductor loop (III), and having a second holder (V) for accommodating at least one luminous means (II) for displaying predefinable coordinates of the entry point (IX)).
