VRAIN: Virtual reality assisted intervention for neuroimaging

The USC Stevens Neuroimaging and Informatics Institute in the Laboratory of Neuro Imaging (http://loni.usc.edu) has the largest collection/repository of neuroanatomical MRI scans in the world and is at the forefront of both brain imaging and data storage/processing technology. One of our workflow processes involves algorithmic segmentation of MRI scans into labeled anatomical regions (using FreeSurfer, currently the best software for this purpose). This algorithm is imprecise, and users must tediously correct errors manually by using a mouse and keyboard to edit individual MRI slices at a time. We demonstrate preliminary work to improve efficiency of this task by translating it into 3 dimensions and utilizing virtual reality user interfaces to edit multiple slices of data simultaneously.
