摘要: Systems, methods, and related computer program products for medical imaging and image-guided radiation treatment (IGRT) are described. In one embodiment, an IGRT system selectively integrates x-ray source arrays, dual-energy imaging, stereoscopic imaging, static and dynamic source collimation, and/or inverse geometry tomosynthesis imaging to acquire and/or track a target during radiation treatment. Advantages include reduced patient x-ray dose and/or reduced treatment delivery margins.

摘要: A method and apparatus for approximating a path of movement of a target. The method includes referencing a temporal sequence of images, identifying a plurality of data points associated with a selected volume element of the volume of interest, and calculating an estimated location of the selected volume element based on a cost function having a constraint which favors continuous spatial motion of the selected volume element over time. Each of the images of the temporal sequence of images depicts a volume of interest. Each of the plurality of data points corresponds to one of the images.
