Acoustic Radiation Force Imaging added to the USTB

We have added an example showing how to use the USTB to do beamforming of high frame rate plane wave images of shear waves induced by an acoustic radiation force push.

The example is available here: http://www.ustb.no/examples/acoustical-radiation-force-imaging/arfi-from-uff-file-recorded-with-verasonics/

  1. Hello Ole Marius and Alfonso Rodriguez-Molares,

    I have a doubt. That is, if I am developing another Beam forming method (METHOD X), other than DAS, how can I compare the outputs produced by DAS and METHOD X?.

    I have chosen center frequency as one of my parameters and compared center frequencies for both DAS and METHOD X. Similarly what are the different parameters I can choose to compare the outputs produced by DAS and METHOD X?. Also what should be the ideal values for the parameters.

    For example, I have chosen center frequency. The ideal value is: 5MHz, DAS output value is: 4.4MHz, METHOD X output value is: 4.1MHz. Similarly, I would like to know what would be the parameter for comparison, their ideal and DAS output values.

    So I would request you to kindly assist me accordingly.

    Thanks,
    Sai..

    1. Hi!

      I suggest that you post this as an issue in the bitbucket repository at https://bitbucket.org/ustb/ustb then we avoid spamming the comment section here 🙂

      I’m not sure why you would want to compare the center frequency between two methods. What’s common to compare is the resolution and contrast, as we have shown for example in the example for the delay multiply and sum: http://www.ustb.no/examples/advanced-beamforming/ . There is plenty more information on how to compare beamformers and metrics through the PICMUS competition : https://www.creatis.insa-lyon.fr/EvaluationPlatform/picmus/index.html.

      Lastly, if you want to compare your method with DAS using the UltraSound ToolBox you should implement your method as a postprocess and compare the resulting image with the resulting image from DAS.

      Please feel free to create an issue in the bitbucket repository and we can discuss more details and code.

      Cheers
      Ole Marius

  2. Hi,

    I created an issue in the repository, but I am not sure whether I did it right or not and so I am posting by doubt here.

    That is, in the ARFI code, you said that you have used CIRS QA Spherical Phantom to collect the data for AFRI Imaging. It contains 4 spheres. Type-1, 2, 3 and 4.

    May I know which type of sphere you have used to collect the data, 1 or 2 or 3 or 4?.

    Thanks,
    Sai..
