Abstract

The invention relates to a system (20) for determining the positioning of a body area (O) of a patient in a magnetic resonance imaging scanner (2), the system comprising a sensor assembly (21) and a data transfer device (22), wherein the data transfer device (22) is designed to transfer the sensor data (SD) of the sensor assembly (21) out of the magnetic resonance imaging scanner (2), and wherein the sensor assembly (21) comprises sensors (D1, D2, D3, S1, S2, S3) which are designed to measure the positioning of the patient's body area (O) on the patient table, and at least some of the sensors are designed and arranged to measure the positioning of the body area (O) when they are attached to, on or under the body area (O). The invention also relates to a method for position determination, to an optical pressure sensor, to an optical position sensor and to a head restraint.
