Abstract: Systems and methods are provided for target tracking using a quality indicator during radiation therapy treatment. An exemplary method may include determining a localization result indicating a location of a target in a plurality of images representative of images acquired in a radiation therapy treatment session. The method may also include determining a quality indicator for each localization result. The method may further include extracting one or more features from each localization result. In addition, the method may include training the classifier using the localization result and one or more of the extracted features.

Abstract: In a solid mechanics simulation of a deformable object having: a model representing a condition of the deformable object; a rendering module for presenting an image of the object in response to states of the elements of the object according to an oriented view; and a user interface for a user to mechanically interact with the model to deform the modeled object; an enhancement is provided that effectively supplies a refined rendering of the set of elements of the object in view, without adding elements to the model, so that the image is of an object defined locally to a higher degree than that of the model.
