We previously presented a crusher coil for suppression of extra-cranial lipids in brain Magnetic Resonance Spectroscopic Imaging (MRSI). To improve crushing performance and the reproducibility of the production of crusher coils, a new crusher coil was designed, created and tested. By doubling the amount of wires and improving their spatial distribution around the coil (consistent meandering), we could achieve efficient lipid suppression with as little as 30% of the power, used with the proof of principle coil. The presented design is easy to reproduce, repair and modify due to a modular build.
