Procedure
Installing the framework
Just run the script examples/script_generate_image.m (in the examples folder). It will carry out the following tasks:
Run the script examples/script_visualize_image.m (in the examples folder). It will open and display the image saved in the previous step.
Image evaluation
Run the script examples/script_evaluate_image.m (in the examples folder). It will carry out the following task:
- Download the PICMUS MATLAB library
- Unzip the dowloaded file into a folder of your choice, for example [picmus_matlab_toolbox]
- Add [picmus_matlab_toolbox] to MATLAB's path without subfolders.
- If you open [picmus_matlab_toolbox] you should see the following file structre
Just run the script examples/script_generate_image.m (in the examples folder). It will carry out the following tasks:
- Download a dataset from the PICMUS website,
- launch the DAS beamformer,
- display the beamformed image,
- and save the image as a hdf5 file in the result folder.
Run the script examples/script_visualize_image.m (in the examples folder). It will open and display the image saved in the previous step.
Image evaluation
Run the script examples/script_evaluate_image.m (in the examples folder). It will carry out the following task:
- Open the image generated by the DAS beamforming code,
- deine a us_picmus_metrics object,
- evaluate the quality metrics of the DAS images, namely
- speckle quality,
- geometrical distortion,
- linearity of output dynamic range,
- constrast,
- full width half maximum, and
- axial/lateral resolution.
- display the resulting metrics in the command line window. Follow the link if you want to learn more on the PICMUS metrics.
