Issue in retracting head model for Focused UltraSound Treatment of Anatomical Head

Hello friends,

I am very new to the Sim4Life software and need your support. I am trying to follow the "Focused UltraSound Treatment of Anatomical Head tutorial." In the tutorial, the software says to save the data from a source, as shown below.

The Problem is that this source link is not available anymore. I tried to find the dataset for the human head, but I couldn't find the ".dcm" extension files. There are the .png files, but not the ".dcm" files. What should I have to do?

Kind regards,

Majid
