Getting started

To get started using MERIT for imaging, a working MATLAB installation is required. MERIT can be used with Windows, Mac OS or Linux.

Downloading

MERIT can be cloned or downloaded from the Github homepage:

First steps

Sample data from the BRIGID dataset is provided to illustrate the imaging pipeline and to allow for easy testing. The getting_started.m script steps though a sample imaging pipeline:

  • load and view raw signals from a breast phantom with a spherical tumour phantom embedded;
  • perform rotational subtraction to isolate the tumour response;
  • visualise the result of the artefact removal from the previous step in the frequency domain;
  • create an imaging domain inside the antenna locations;
  • create a function to calculate the propagation delays from the antennas to points within the imaging domain;
  • perform the imaging in the frequency domain using the DAS beamformer;
  • use the visualisation functions to get a coronal slice of the resulting image;
  • graph the slice using existing MATLAB functions.

This script highlights the basic functionality of the MERIT toolbox. Further examples illustrate how the stages in the imaging process can be configured, extended and optimised with minimal changes.
