DSPView is a GUI and framework for elastrographic processing on ultrasound data.
See this YouTube video for functionality:
See the GitHub repository for a nice readme file:
See my master's thesis, for which DSPView was written,
for more details on algorithms etc:
The input is raw RF data, while the output can be normal ultrasound B-mode image, a velocity image (axial velocity distribution), an axial strain image or an elastrographic image.
Elastographic imaging makes it possible to image tissue density, something which is not necessarily discernible with norma B-mode imaging.
