Area ROI

    I am trying to measure an ACR phantom. I am trying to get the circle ROI area in mm. I can find mean, min, and max. There is a field labeled SD. I don't know what that is, or what it means. Is there a way to get ROI area?

    Dear tamsrick


    The ROI measurement tools are intended to measure the density of a specific area. In general, they do not include an area size measurement. Our professional reading station iQ-VIEW PRO offers an additional Polygonal ROI measurement, which also includes the calculation of the area size. Check out the website and you will find the option to download a trial version.


    By the way, SD stands for standard deviation, which is calculated on the basis of the different density values found in the specified area.
