Patent number: 11960035Abstract: Systems and methods for encoding radiofrequency, RF, data, e.g., electrical signals, by a microbeamformer are disclosed herein. The microbeamformer may use a pseudo-random sampling pattern (700) to sum samples of the RF data stored in a plurality of memory cells. The memory cells may be included in a delay line of the microbeamformer in some examples. The summed samples may form an encoded signal transmitted to a decoder which reconstructs the original RF data from the encoded signal. The decoder may use knowledge of the pseudo-random sampling pattern to reconstruct the original data in some examples.Type: GrantFiled: April 30, 2020Date of Patent: April 16, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gregory Tsiang Ely, Faik Can Meral, Jean-Luc Francois-Marie Robert

Patent number: 11647991Abstract: 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: GrantFiled: May 9, 2019Date of Patent: May 16, 2023Assignee: 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

Patent number: 11633172Abstract: An ultrasound imaging system which uses multiline receive beamforming for synthetic transmit focusing are phase adjusted to account for speed of sound variation in the transmission medium. The phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the frequency domain for both the transmit angular spectrum and the receive angular spectrum. The phase variation is removed in the frequency domain, then an inverse Fourier transform is used to transform the frequency domain results to the spatial domain. In another implementation, the phase discrepancy of the received multilines is estimated and corrected entirely in the spatial domain.Type: GrantFiled: May 13, 2019Date of Patent: April 25, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jean-Luc Francois-Marie Robert, Sheng-Wen Huang, Francois Guy Gerard Marie Vignon, Jun Seob Shin, Seungsoo Kim, Faik Can Meral

Patent number: 11372094Abstract: An ultrasonic diagnostic imaging system acquires received beams of echo signals produced in response to a plurality of transmit events. The received beams are combined with refocusing to account for differences in receive beam to transmit event locations. The delays and weights used in the refocusing are supplemented with delays and weights which correct for reverberation artifacts. The received echo signals are processed to detect the presence of reverberation artifacts and a simulated transmission of reverberation signal components to virtual point sources in the image field is calculated. This simulation produces the delays and weights used for reverberation signal compensation, or estimated reverberation signals which can be subtracted from received echo signals to reduce reverberation artifacts.Type: GrantFiled: May 9, 2018Date of Patent: June 28, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Faik Can Meral, Francois Guy Gerard Marie Vignon, Jean-Luc Francois-Marie Robert
