We are doing a laboration study and we want to take a ROI (decide an area in the image) of the bottles in the MR image using MATLAB to get a mean intensity value. We have tried roipoly, a function in MATLAB, but the thing is that the output will create a binary mask image, and that is not what we want.The phantom which illustrates five bottles (Click to see the image)

Thanks

After you get the mask using roipoly, you can get the ROI (as a linear array) by doing roi_data = image(mask)
