Abstract
A radio frequency RF transmit coil () for transmitting an RF field into a magnetic resonance examination zone () of a magnetic resonance imaging system () with a carrier structure () for separating the examination zone () from the RF transmit coil (), wherein the carrier structure () is surrounded by an RF transmit antenna () of the RF transmit coil. The carrier structure () is made of a first material having a first dielectric permittivity, wherein at least one recess () is foreseen in the carrier structure () between a layered capacitors structure () of the RF transmit antenna and a patient () in the examination zone (), wherein the recess () extends fully circumferentially along the carrier structure (). The recess () is filled with at least a second material, so that the second material encircles the carrier structure () as an extra layer, the second material having a second dielectric permittivity, wherein the second dielectric permittivity of the second material is higher as the first dielectric permittivity of the first material of the carrier structure ().
