Magnetic resonance imaging device and method for positioning a medical instrument

A medical instrument for an interventional procedure, the medical instrument comprising:

• an elongate shape having a proximal end and a distal end;
• and
• an optical image capturing apparatus positioned at the distal end,
• wherein the optical image capturing apparatus is configured to capture a display of a magnetic resonance imaging device at least partially in a map, and
• wherein the display is arranged along a circumferential direction in a recess of a patient tunnel of the magnetic resonance imaging device.

A method for aligning a medical instrument on a body of a patient in a patient tunnel of a magnetic resonance imaging device having a display arranged along a circumferential direction in a recess of the patient tunnel, wherein the medical instrument has an elongate shape having a proximal end and a distal end, and wherein the method comprises:

• ascertaining a trajectory for the medical instrument in the patient for a predetermined interventional procedure;
• identifying an entry point on the patient and an impact point on the display of the magnetic resonance imaging device, wherein the entry point and the impact point define a straight line through the trajectory in a position of the patient for the predetermined interventional procedure;
• positioning the medical instrument at the entry point by a user;
• marking the impact point by outputting a marking on the display;
• and
• aligning the distal end of the medical instrument with the marking.
