METHOD AND APPARATUS FOR TARGETING A TUMOR DURING RADIOTHERAPY USING A VIRTUAL IMAGE

摘要

A method and apparatus for targeting a cancerous lesion or tumor during radiotherapy or radiosurgery comppsing the steps of pre-operatively scanning the surgery site using one of magnetic resonance imaging, positron emission tomography or computed tomography to identify the tumor and plan the surgery Intra-operatively scanning the site with ultrasound and overlaying the live ultrasound scan on top of the pre-operative scan Registration of the two images is achieved using image deformations and an average arbitrary normal patient image atlas The method allows registration of the multimodal images for the tracking of the target dupng surgery.
