摘要：

Accurately repositioning the patient with respect to CT or MR images is essential for high precision radiotherapy. We show that portal images may be automatically registered with 3D pre-session data (typically morphological images like CT or MR images), thus enabling an automatic adjustment of the planned strategy to the actual position of the patient. Based on computer vision techniques, the principles of this new method of multimodal image registration are presented, and the first experiments with a phantom are analysed.
