The hole-slot magnetron is used as a HF oscillator in radar applications. A surface coil based on the hole-slot magnetrons geometry was introduced showing deeper RF penetration than a conventional coil at 1.5 and 4 Tesla. Four different conventional coil geometries were compared with a hole-slotted coil at 7 Tesla. Furthermore a hole-slotted array was built and evaluated. The hole-slotted loop improves RF penetration depth compared to the different loops showing a improved SNR in the second half of the phantom. The images acquired with the hole-slotted array show high SNR as well as good homogeneity and RF penetration depth.
