Hello, in radiation therapy we are very interested in knowing the profile of the Hounsfield Units(HUs) of the pixels of our CT scans. In ImageJ ([ImageJ](https://imagej.nih.gov/ij/)) we can get the profile of the HUs with a simple (ctrl + k). Is there any simple equivalent in 3D Slicer? Is it hard to implement one? In the image below for instance I can draw a line and get the HUs profile instantly. Thank you. ![Screenshot from 2022-02-02 18-30-28](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/a/3/a3a968760f584d2b736219368e7bb7784ca6e55a.png) ---

This feature is available in `Line profile` module provided by the Sandbox extension. ---
