摘要： Disclosed are imaging systems, methods, and computer program products that generate estimates of scattered radiation in tomographic imaging systems, such as cone-beam computerized tomography (CBCT) systems, and the like. In an exemplary embodiment, a first group of projections is taken of an object with the radiation covering a wide band of the object, and a second group of projections is taken of the object with the radiation covering a narrower band of the object. The projections of the second group cover less of the object, but have less scattered radiation. The scattered radiation within the narrower band may be estimated from differences between projections from the first and second groups, or from representations thereof.

摘要： In one example of an embodiment of the invention, a method to correct for ring artifacts in an image is disclosed. A first Cartesian image is reconstructed based on data received from an imaging device, and the first Cartesian image is transformed into a first polar image. A first low-pass filter is applied to the first polar image, in the radial dimension, to form a second polar image, and the second polar image is subtracted from the first polar image to generate a third polar image. A second low-pass filter is applied to the third polar image, in an angular dimension, to form a fourth polar image, and the fourth polar image is transformed to Cartesian coordinates to form a second Cartesian image. The first Cartesian image is corrected based, at least in part, on the second Cartesian image.

摘要： One example method for estimating scatter associated with a target object may include acquiring a set of original projection data that includes primary radiation and scattered radiation at one or more selected projection angles associated with the target object, generating a first set of estimated scatter data from the set of original projection data, generating reconstructed image data by performing a first pass reconstruction using the first set of estimated scatter data, and generating a set of reference scatter data associated with the target based on the reconstructed image data. The example method may also include generating a set of reference primary plus scatter data associated with the target object based on the reconstructed image data, generating a second set of estimated scatter data associated with the target object based on the set of reference primary plus scatter data, and generating perturbation data associated with the target object.
