Method and control device for determining the position of a local coil on a patient table of a magnetic resonance scanner |
摘要 |
In a method and control device for determining the position in at least one spatial direction of a local coil on a patient table in a scanner of a magnetic resonance tomography apparatus, a radio-frequency signal is emitted in the presence of a magnetic field gradient applied in the appertaining spatial direction and a signal profile is measured by the local coil along the magnetic field gradient. The signal profile is acquired for each of a number of positions of the patient table relative to the scanner along the magnetic field gradient. Based on the measured signal profile the position of the local coil is determined.
