A connection device is provided for connecting electronics of a head coil
arranged on a patient support to a connector location provided on the
patient support, the head coil being insertable into a PET detector
arranged in a magnetic resonance instrument so that simultaneous magnetic
resonance and PET recording is possible. In at least one embodiment, the
connection device includes a cable connection with at least one
releasable device for attachment to the electronics and the connector
location, wherein the cable connection is fed from the electronics
through the annular PET detector and externally on the PET detector back
to the connector location.
