Abstract :
Develops an innovative image reconstruction technique for reflection tomography based upon the extraction of multiple-bounce (MB) ghosting artifacts. The basic concept is that the time-of-flight between the transmission and reception of a waveform includes the realistic effects of MB interactions. An enhanced quality image can be constructed by utilizing only the single-bounce (SB) contributions of the measured time-of-flight projection data. In addition, the MB ghosting artifacts are projected into a series of auxiliary images that can be applied to enhance performance of object identification. These novel methods can be applied to any domain of medical imaging which is based upon the concepts of reflection tomography, such as ultrasound.
