MR Safety Officer responsibilities ~~> The role of MRSO is often carried out by the senior Radiographer (in the USA this will generally be an MR technologist), but other suitably trained individuals could also fill this role. Multiple MRSOs could be appointed, provided only one is in charge at a given time. His/her responsibilities include the following: To be readily accessible and available (eg, to the operators of the MR system) at all times that the MR facility is accessible....
