Abstract
This invention generally relates to the removal of streaking artifacts and periodic noise from tomographic images. The method comprises obtaining an A-scan from an imaging data set. The A-scan having a signal and the signal defining an amplitude. Noise specific to the A-scan is estimated. The amplitude of the A-scan is scaled based on its specific estimated noise floor. In another aspect, a plurality of A-scans is obtained from an imaging data set. Each of the plurality of A-scans has a signal and the signal defines an amplitude. Noise specific to each A-scan of the plurality of A-scans is estimated. Each A-scan of the plurality of A-scans is scaled by the A-scan's specific estimated noise floor.
