I am relatively new to Image J. I am using it to quantify vessels in a defined area between two circles (donut) using the concentric circle plugin. Also, I’ve thresholded the image to highlight these capillaries to obtain the area. However, I desire separate measurements of area for each of 8 equally divided regions of the donut. Any advice on how to create these 8 equal regions of the donut in order to obtain their area? The creation of quadrants would also be permissible.
Thank you for any help!
