Motion-compensated Cone-beam CT For Accurate Online Assessment Of The Position Of Lung Tumours

High precision radiotherapy requires accurate tumour localisation for patient positioning just prior to treatment. Respiratory motion induces artifacts in cone-beam (CB) CT images of the thorax and upper abdomen which can prevent an accurate localisation of tumours. Respiration-correlated reconstruction has been used to correct for this motion.
