Hello, everyone,
I need your help again.
In my project, I have to cut out the circles in a CTPahntom image as ROIs. The radius and coordinates of the individual circles are known.
Unfortunately, the "imcrop" function does not work with circles.
Does anyone have an idea how I can cut the circles out of the phantom image
Warm greetings

See attached demos. I'm sure adapting one of them, like circle_masking_demo.m, should work.
