Abstract

A detector unit for arrangement in a field generating unit of a magnetic resonance device has an RF transmission/reception system for transmitting RF pulses into, or receiving magnetic resonance signals from, an examination volume of the field generation unit. The RF transmission/reception system surrounds a patient tunnel at a radial distance from a tunnel axis thereof, and is divided into two sub-systems located at a distance from each other along the direction of the tunnel axis, so as to form a substantially annular cavity or interstice therebetween.
