Respiratory motion is a major obstacle in radiation therapy of thoracic and abdominal tumors. Techniques to cope with it such as gating and tracking techniques are based on the use of breathing signals that can be acquired easily and in real-time. These signals represent only surrogates of the motion of the inner organs and tumors. Consequently, methods are needed to estimate respiratory motion patterns of the internal structures based on surrogate measurements. In this contribution, a… CONTINUE READING
