Abstract
Magnetic resonance apparatus includes a magnet system (1) for generating a steady magnetic field in a measurement space (29), a coil system (3) for generating gradient fields in the measurement space, and at least one RF coil (9) which is accommodated in a housing (33) which can be arranged in the measurement space and which is suitable to accommodate an object (41 ) to be examined, and a jig for positioning an instrument (57) introduced into the object (41). This jig has a first stop (59) for defining the position of a free end of the instrument (57) in a first coordinate direction (Z) of a three-dimensional system of coordinates. The jig also has a perforated plate (55) which is provided with holes (53) which are arranged in a matrix which extends according to second and third coordinate directions (X, Y) of the coordinate system in order to position the instrument (57) in the second and third coordinate directions. The location of a coordinate axis extending parallel to the second or the third coordinate direction (X, Y) is defined by a first phantom (71) which is rigidly arranged in the housing (33).
