Publication number: 20210196238Abstract: In an ultrasound imaging system which produces synthetically transmit focused images, the multiline signals used to form image scanlines are analyzed for speed of sound variation, and a map 60 of this variation is generated. In a preferred implementation, the phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the angular spectrum domain for the receive angular spectrum. Once the phase is estimated for all locations in an image, the differential phase between two points at the same lateral location, but different depth, is computed. This differential phase is proportional to the local speed of sound between the two points. A color-coded two- or three-dimensional map 60 is produced from these speed of sound estimates and presented to the user.Type: ApplicationFiled: May 9, 2019Publication date: July 1, 2021Applicant: Koninklijke Philips N.V.Inventors: Jean-Luc Francois-Marie ROBERT, Sheng-Wen HUANG, Francois Guy Gerard Marie VIGNON, Jun Seob SHIN, Seungsoo KIM, Hua XIE, Man NGUYEN, Faik Can MERAL, William Tao SHI, Carolina AMADOR CARRASCAL
