    • Synthetic Aperture Focusing of Ultrasonic Data From Multilayered Media Using an Omega-K Algorithm 

      Skjelvareid, Martin H.; Olofsson, Tomas; Birkelund, Yngve; Larsen, yngvar (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      The synthetic aperture focusing technique (SAFT) is used to create focused images from ultrasound scans. SAFT has traditionally been applied only for imaging in a single medium, but the recently introduced phase shift migration (PSM) algorithm has expanded the use of SAFT to multilayer structures. In this article we present a similar focusing algorithm called multi-layer omega-k (MULOK), which ...
