Scanbuddy: fMRI motion plotting and SNR estimation at scan acquisition

Functional magnetic resonance imaging (fMRI) is a powerful research and clinical tool for in vivo imaging of human brain function.Scanbuddy is containerized software that produces motion plots at the time of scan acquisition.Users should have a machine separate from the scanner host PC with its own display monitor that is capable of running Linux and Docker.Users can set up auto exporting from the scanner host PC via a Samba share mount for BOLD scans.With auto exporting, the scanner will automatically send reconstructed DICOMs to both the scanner host PC and the Scanbuddy machine.Scanbuddy uses the excellent dcm2niix (Li et al., 2016) and AFNI (Cox, 1996) packages for DICOM conversion and computing motion estimates.Scanbuddy was developed in a linux environment and can handle repetition times as fast as 0.6 seconds.
