Abstract
Techniques are disclosed for positioning a patient within a patient receiving area for a magnetic resonance examination. The techniques may include positioning the patient on a mobile patient table of a patient support facility and moving the patient table in a first horizontal direction until a region of the patient to be examined is arranged in a field of view of a patient receiving area of a magnetic resonance system. Moreover, the patient positioning techniques may include moving the patient table in a second horizontal direction and/or in a vertical direction within the patient receiving area, and acquiring medical magnetic resonance data of the region of the patient to be examined.

A method for positioning a patient within a patient receiving area of a magnetic resonance scanner to perform a magnetic resonance examination, the method comprising:
- positioning the patient on a movable patient table of a patient support;
- controlling, via processor circuitry, one or more drive elements associated with the patient table to move the patient table in a first horizontal direction until a first region of the patient to be examined is arranged in a Field of View (FoV) of the magnetic resonance system,
- controlling, via the processor circuitry, the one or more drive elements associated with the patient table to move the patient table in a second horizontal direction and/or to move the patient table in a vertical direction within the patient receiving area to position the first region of the patient within a detection area of the magnetic resonance system within which magnetic resonance signals are acquired, and to position a second region of the patient outside the detection area and outside a critical field extent of a magnetic field of the magnetic resonance system;
- and
- acquiring, via the magnetic resonance scanner, medical magnetic resonance data of the first region of the patient to be examined,
- wherein the positioning of the first region of the patient and the second region of the patient prevents objects within the second region of the patient from causing artifacts in the medical magnetic resonance data that is acquired with respect to the first region of the patient.
A magnetic resonance system, comprising:
- a magnetic resonance scanner including a basic field magnet, a gradient coil unit, and a radio-frequency antenna unit;
- a patient receiving area surrounded by the magnetic resonance scanner;
- and
- a patient support having with a patient table that is movable with respect to the patient receiving area in each of (i) a first horizontal direction, (ii) a second horizontal direction, and (iii) a vertical direction to position a first region of a patient within a detection area of the magnetic resonance system within which magnetic resonance signals are acquired, and to position a second region of the patient outside the detection area and outside a critical field extent of a magnetic field of the magnetic resonance system,
- wherein the positioning of the first region of the patient and the second region of the patient prevents objects within the second region of the patient from causing artifacts in the medical magnetic resonance data that is acquired with respect to the first region of the patient.
A non-transitory computer readable media associated with a magnetic resonance system that includes a magnetic resonance scanner, the non-transitory computer readable media having instructions stored thereon that, when executed by processor circuitry, cause the magnetic resonance system to:
- generate control signals to control one or more drive elements associated with a patient table of a patient support associated with the magnetic resonance system to move the patient table in a first horizontal direction until a first region of a patient to be examined is arranged in a Field of View (FoV) of a patient receiving area of the magnetic resonance system,
- generate control signals to control one or more drive elements associated with the patient table to move the patient table in a second horizontal direction and/or to move the patient table in a vertical direction within the patient receiving area to position the first region of the patient within a detection area of the magnetic resonance system within which magnetic resonance signals are acquired, and to position a second region of the patient outside the detection area and outside a critical field extent of a magnetic field of the magnetic resonance system;
- and
- acquire, via the magnetic resonance scanner, medical magnetic resonance data of the first region of the patient to be examined,
- wherein the positioning of the first region of the patient and the second region of the patient prevents objects within the second region of the patient from causing artifacts in the medical magnetic resonance data that is acquired with respect to the first region of the patient.
