Methods to Improve Target Delineation and Reduce Intra- and Inter-User Variability for Essential Tremor Treatments

Austin Kirschner, MD, PhD, from the Radiation Oncology Department at Vanderbuilt University Medical Center presents methods for improving target delineation and reducing intra- and inter-user variability for essential tremor treatments. He begins by giving an overview of essential tremor, focusing then on their stereotactic radiosurgery (SRS) clinical trial at Vanderbilt. He discusses the reproducibility and accuracy of SRS before outlining the features of Elements software such as auto-contouring, MRI distortion correction, diffusion tensor imaging (DTI) and fiber tractography. Finally, he presents an analysis of Elements features as they relate to tremor control in clinical patient data.
