System and method for tomographic data acquisition and image reconstruction |
摘要 |
A tomographic system includes a gantry having an opening for receiving an object to be scanned, a radiation source, a detector positioned to receive radiation from the source that passes through the object, and a computer. The computer is programmed to acquire a plurality of projection datasets of the object, define a temporal subset of projection datasets from the plurality of projection datasets, reconstruct a working image of the object using the plurality of projection datasets, identify a region of motion in the working image, and minimize motion artifacts in the region of motion in the working image using the temporal subset of projection datasets. |

1. A tomographic system comprising:
a gantry having an opening for receiving an object to be scanned; a radiation source; a detector positioned to receive radiation from the source that passes through the object; and a computer programmed to:
acquire a plurality of projection datasets of the object;define a temporal subset of projection datasets from the plurality of projection datasets;reconstruct a working image of the object using the plurality of projection datasets;identify a region of motion in the working image; andminimize motion artifacts in the region of motion in the working image using the temporal subset of projection datasets.
