摘要
A computerized tomographic system configured to acquire short scan data of an object within a single revolution of a detector array about the object over a first angular range of rotation of the detector array about the object, define a temporal subset of the acquired short scan data over a second angular range of rotation of the detector that is less than the first angular range of rotation, generate a mathematical function that is based on the acquired short scan data and the defined temporal subset of data, minimize the mathematical function, and generate an image of the object using the minimized mathematical function and the data acquired over the second angular range of rotation of the detector.
