Correction to: Nature Biomedical Engineering https://doi.org/10.1038/s41551-018-0278-y, published online 9 August 2018.

In the version of this News and Views article originally published, the author name, title and year were incorrect in ref. 14 and should have read “Yang, X. et al. Coaxial cable magnetic resonance image (MRI) coil. US patent US9678180B2 (2017).” This error has now been corrected.
