Hi there


I want to do a study that measures the influence of the size of regions of interest (ROIs) and want to do the following:

1) create multiple (n=10-20) point annotations in images and save them, allowing to go to them when later opening the image again
2) draw circles on these point annotations but in such a way that a point annotation is the centre of the circle
3) remember the radius/area/perimeter of these circles and export them in a structured way

Ideally I can do this on my very big images (Mirax files), but it may also be possible to create some images (.jpg, .bmp, ...) of certain regios in the Mirax file and do the circle drawing on these.


All help and suggestions welcome

Thanks!
Koen
