摘要： There is disclosed a method for estimating the position of a target in a body of a subject. The method includes, receiving an external signal that is related with motion of the target; and using a model of a correlation between the external signal and the motion of the target to estimate the position of the target, wherein said position estimation includes an estimate of three dimensional location and orientation of the target. The method further includes periodically receiving a 2-dimensional projection of the target; and updating the model of correlation between the external signal and the motion of the target based on a comparison of the estimated position of the target and the 2-dimensional projection of the target. The method is used in guided radiation therapy.

摘要： The present invention is concerned with a method and system for guiding a radiation therapy system. The method comprises: capturing an image of a target area to which radiation is to be delivered; analysing the image with a trained convolutional neural network to determine the position of one or more objects of interest present in the target area; and outputting the determined position/s to the radiation therapy system.
