#16 Multi ROI Uniformity Error

[Matthew Donoghue]

When I attempt to add new ROI's to the multi-uniformity test, the ROI's appear as none in the multi-uniformity properties under processing parameters. There are both central and peripheral elliptical ROI's placed on a uniformity phantom image and edge detection is not used.

Thanks,

Matthew Donoghue
