A major function of the human brain is to mediate interactions with other people. Until recently, studying social interactions as they occur within the brain was not possible due to the lack of measurable methods to observe two interacting minds simultaneously. We have developed a novel MRI dual‐head volume coil pair that can scan two subjects' brains simultaneously while the subjects are socially interacting in one MRI scanner. The feasibility of using this coil for dyadic functional MRI (fMRI) study has been successfully demonstrated for the first time. Meanwhile, an innovative robust scheme for decoupling two circular‐polarized coils (not surface coils) is introduced in theory and validated in practice in the coil technology development.
