Method of acquiring images of a plane in a magnetic resonance apparatus and magnetic resonance apparatus suitable for carrying out such a method

The invention relates to a method of acquiring images of a plane in a magnetic resonance apparatus, notably to a method of introducing a medical instrument into the body of a patient in a magnetic resonance apparatus where a position of a tissue to be treated has been determined in three dimensions and also a position of entry for the medical instrument, in which method a path to be followed by the medical instrument is defined by way of at least two different images of body cross-sections through said positions in the magnetic resonance apparatus, said medical instrument being guided along said path so as to reach the tissue to be treated, a plane to be imaged being defined by means of a further image in the magnetic resonance apparatus and the point of intersection of the path to be followed by the medical instrument and said plane to be imaged being indicated in said further image, the medical instrument being maintained at said point of intersection, viewed in the plane to be imaged, during its introduction. In a method for acquiring an image of a plane in a magnetic resonance apparatus, the images are obtained in imaging planes which are defined directly with respect to the patient. The magnetic resonance apparatus includes an imaging volume, a patient support table which positioned in the imaging volume, a position measuring device to establish and maintain in real time the position of the patient, as well as a controller for controlling gradient coils in response to the signals provided by the position measuring device in such a manner that consecutive images are acquired from imaging planes which are defined directly with respect to the patient.
