Research

Dr Murphy's current research programs are in medical image analysis and registration, machine vision, and automatic control systems for motion-adaptive radiation therapy. He is interested in the application of pattern recognition algorithms to image analysis, the modeling of respiration with neural networks, novel methods of reconstructing computed tomography images, and motion tracking in radiation therapy.
