METHODS AND SYSTEMS FOR ESTIMATING SCATTER |
摘要 |
<p>Techniques described herein generally relate to estimating scatter. In one embodiment, one example method for estimating scatter associated with a target object may include generating a set of original projections associated with the target object, generating a set of reference scatter data associated with the target object at one or more selected projection angles, generating a first set of estimated scatter data associated with the target object also at the one or more selected projection angles, adjusting first values for one or more kernel parameters of one or more kernels that reduce a difference between the set of reference scatter data and the first set of estimated scatter data, interpolating the adjusted first values for remaining projections out of the set of original projections to generate second values for the one or more kernel parameters, and generating a second set of estimated scatter data associated with the target object.</p> |
