Abstract
A head coil for a magnetic resonance apparatus has a mirror device for the stimulation of one or both eyes with first light in a first wavelength range and for simultaneous acquisition of a eye movement with second light in a second wavelength range in a functional magnetic resonance examination. The mirror device has a mirror that reflects the first light and is transmissive for the second light or that is transmissive for the first light and reflects the second light.
Claims28
A head coil for use in a magnetic resonance apparatus comprising:
- a radio-frequency coil;
- a mirror device adapted for placement in association with said radio-frequency coil relative to a head of a patient to stimulate at least one eye of said patient with a first light in a first wavelength range and for simultaneously identifying eye movement of said patient with a second light in a second wavelength range in a functional magnetic resonance examination;
- and
- said mirror device having a mirror which reflects one of said first light and said second light and transmits the other of said first light and second light.
A head coil as claimed in claim I wherein said first light is visible light and wherein said second light is infrared light.
A magnetic resonance apparatus comprising:
- a magnetic resonance scanner for conducting a functional magnetic resonance examination of a patient, said magnetic resonance scanner having a radio-frequency coil;
- a mirror device adapted for placement in association with said radio-frequency coil relative to a head of said patient to stimulate at least one eye of said patient with a first light in a first wavelength range and for simultaneously identifying eye movement of said patient with a second light in a second wavelength range in said functional magnetic resonance examination;
- and
- said mirror device having a mirror which reflects one of said first light and said second light and transmits the other of said first light and second light.
A mirror device for use in a magnetic resonance apparatus comprising:
- a housing adapted for placement in association with a radio-frequency coil relative to a head of a patient to stimulate at least one eye of said patient with a first light in a first wavelength range and for simultaneously identifying eye movement of said patient with a second light in a second wavelength range in a functional magnetic resonance examination;
- and
- a mirror at said housing which reflects one of said first light and said second light and transmits the other of said first light and second light.
