Systems and methods for continuous ultrafast ultrasound beamforming with programmable logic

Abstract

Systems and methods for ultrafast imaging include: a memory having stored thereon a delay profile matrix and a field programmable gate array (FPGA) coupled with the memory. The delay profile matrix comprises a two-dimensional matrix in which each row corresponds to a delay profile at a particular depth. The FPGA is configured to: acquire radio frequency (RF) ultrasound data from a subject; load a delay profile from the delay profile matrix to a memory buffer of the FPGA, wherein the delay profile corresponds to a particular depth; read a first row of the RF ultrasound data based on a first delay value of the delay profile; generate beamformed data at the particular depth by beamforming the first row of RF ultrasound data; and generate an image of the subject based on the beamformed data.
