The four coordinate systems of interest in optically tracked FUS. The transducer steering coordinate system can be related to the imaging coordinate system through a series of transformations which allow for accurate targeting of specific brain structures with FUS. An infrared stereocamera (*) is used to locate the transducer in physical space and 3D Slicer (†), Slicer IGT (‡), and the PLUS server (§) are used to connect this camera to a MR viewing environment.
