| 摘要 | A method of determining a model of a marker includes obtaining projection images, each of the projection images having an image of a marker that indicates a shape of the marker, determining binary images of the marker for respective ones of the projection images, and constructing a three-dimensional model of the marker using the binary images, the three-dimensional model comprising a set of voxels in a three-dimensional space that collectively indicates a three-dimensional shape of the marker, wherein the act of constructing the three-dimensional model is performed using a processing unit. | ||

| 主权项 | 1. A method of determining a model of a marker, comprising: obtaining projection images, each of the projection images having an image of a marker that indicates a shape of the marker, the marker being a physical object implanted inside a patient; determining binary images of the marker for respective ones of the projection images; and constructing, using a processing unit, a three-dimensional model of the marker using the binary images, the three-dimensional model comprising a set of voxels in a three-dimensional space that collectively indicates an actual three-dimensional shape of the marker. | ||
