Research

Dr. Elder's research centers on techniques for adaptive radiation therapy, adjustments to a patients radiation treatment caused by changes in patient position, anatomy, or motion or due to tumor response. Methods of visualization of these changes include 3D and 4D computed tomography and linear accelerator mounted cone beam computed tomography, radiography, and respiratory gated fluoroscopy and radiography. After visualization and tumor delineation, treatment planning is performed to adapt treatment properly. Use of electronic portal dosimetry to measure exit does is also being explored.
