Convex optimization of sensor positions for organ-positioning during radiotherapy

Other conference contribution, 2012

Real-time organ positioning is a promising technique for enhancing radiotherapy of cancer tumors in situations where the tumor position can be believed to change between imaging and treatment and/or during treatment. In this work, we exploit theory on optimal measurements to formulate an optimization problem for the sensor positions of a magnetic tracking system. The optimization problem is relaxed into a convex problem, which is subsequently solved.
