Dear All,

```
 Calculation and analysis of ventricular Global longitudinal strain(GLS) and other strains based on Ultrasound has been research hotspots, is there any extension in Slicer or in the future plan?

 Or anyone can share some open-source calculation framework on US（CT/MRI）?

 Best wishes.

I found one publication "CardIAc: an open-source application for myocardial strain analysis "

I am not sure whether the same.  
Currently, the CardIAc extension has not published in the Slicer 5.2.2 version ?  
thanks
