Real time GPU Beamformer for ultrafast ultrasound imaging

This repository contains GPU-accelerated codes for real-time reconstruction of plane wave images. These includes: *CPU delay-and-sum beamformer *CPU Fourier beamformer *GPU delay-and-sum beamformer *GPU Fourier beamformer

The GPU programs are written in C/CUDA but interface with matlab using mex function for real-time visualisation and integration with Vantage research ultrasound scanner

Requirements

The program works for both Windows and linux system and has been tested using:

• matlab 2017b
• cuda toolkits 9.0
• visual studio 2015 (windows)

Installation

Clone this repository

git clone https://github.com/andyleow/Ultrasound_image_reconstruction.git

To compile the GPU from source code, user can either execute the "makefile.m" from matlab or independently execute the following commands in the src file directory in Matlab

• Windows

mex -largeArrayDims -f nvcc_msvcpp2015.xml NVCC_FLAGS="" -v cuDAS_int.cu cuDAS_function.cu
mex -largeArrayDims -f nvcc_msvcpp2015.xml NVCC_FLAGS="" -v cuDAS_single.cu cuDAS_function.cu
mex -largeArrayDims -f nvcc_msvcpp2015.xml NVCC_FLAGS="" -v cuFBF_int.cu cuFBF_functionV1.cu
mex -largeArrayDims -f nvcc_msvcpp2015.xml NVCC_FLAGS="" -v cuFBF_single.cu cuFBF_functionV1.cu

• Linux

mex -largeArrayDims -f nvcc9_g++.xml NVCC_FLAGS="" -v cuDAS_int.cu cuDAS_function.cu 
mex -largeArrayDims -f nvcc9_g++.xml NVCC_FLAGS="" -v cuDAS_single.cu cuDAS_function.cu 
mex -largeArrayDims -f nvcc9_g++.xml NVCC_FLAGS="" -v cuFBF_int.cu cuFBF_function.cu 
mex -largeArrayDims -f nvcc9_g++.xml NVCC_FLAGS="" -v cuFBF_single.cu cuFBF_function.cu
