摘要：
A limiting factor for the effective delivery of radiotherapy to lung tumours is the tumour motion as the patient breathes. If the tumour position is known at all times then treatment parameters may be adjusted accordingly. We formulate a general approach to model the spatial relationship between an external respiratory signal and the tumour position. The model treats the tumour as a point mass attached to a spring-dashpot system driven by abdominal motion. We present the model and show results of numerical computations based on clinical data.
