Hi,<br>I am using qdec for analysis and noticed that in addition to thickness measures I can select others such as area and volume.&nbsp; I have been trying to figure out what exactly the area measure refers to (surface area, etc.).&nbsp; I did not find it on the website.&nbsp; Can someone clarify that for me?&nbsp; If this is a repeat question, I apologize and ask that you point me to the archived post.<br>

<br>Thank you,<br>Dev<br>
