Abstract

A computer-implemented method for managing Cone Beam Computed Tomography, CBCT, imaging of a patient. The method comprises acquiring (102) radiotherapy treatment plan, RTP, information for a RTP. The RTP is for delivering a radiation dose distribution to the patient so as to respect at least one radiotherapy treatment objective. The method further comprises determining (104), based on the acquired RTP information, a measure of sensitivity of the RTP to changes in anatomy of the patient. The measure of sensitivity is a function of position in the patient or a function of radiotherapy beam direction in the RTP. The method further comprises generating (106), based on the determined measure of sensitivity, an imaging protocol for obtaining a reconstructed CBCT image of a volume of the patient by setting a value of at least one parameter in the imaging protocol such that image quality of the reconstructed CBCT image of the patient volume meets an image quality objective for an image processing task. The image quality objective prioritises image quality for positions within the patient volume at which the RTP is sensitive to changes in anatomy. The imaging protocol comprises values for at least one CBCT imaging acquisition parameter and/or at least one CBCT imaging reconstruction parameter.
