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.

@Image Analyst

thank you very much for your great help
