ABSTRACT:
Sets of raw profile data are acquired from a subject using an ultrasound reflective mode tomographic scan. This raw data is corrected for errors due to inhomogeneities in the speed of sound and an image is reconstructed from the corrected data set. The corrections are made by shifting each set of raw profile data such that a prominent signal therein aligns with a corrective sinusoid which indicates the ideal location of the prominent signal in each set of profile data.
