摘要：
An imaging technique is provided for acquiring scatter free images of an object. The technique includes acquiring a plurality of projection images of the object using a source and a detector oriented at a plurality of projection angles relative to the object, and generating a plurality of scatter free projection images by correcting the plurality of projection images based on respective ones of a plurality of stored scatter images. The scatter images are generated and stored for each of the projection angles by positioning a scatter rejection plate between the object and the detector. The technique further includes reconstructing a three-dimensional image of the object based on the scatter free projection images.
摘要（中）：
提供了一种用于获取物体的无分散图像的成像技术。 该技术包括使用源和相对于物体以多个投影角定向的检测器获取对象的多个投影图像，并且通过基于相应的对象来校正多个投影图像来生成多个无散射投影图像 的多个存储的散射图像。 通过在物体和检测器之间放置散射抑制板，为每个投影角度生成和存储散射图像。 该技术还包括基于无分散投影图像来重建对象的三维图像。
