They are relatively easy to make in ID. It is pretty much the same as using Illustrator.
Make two circles, center them. I color them differently just so I can see them.
Select both, use the Object menu, Pathfinder, Subtract. You will then have the outer ring.
Create a rectangle the width that you desire to create the segment separation.
Center it on the ring, like shown in the above screen shot.
Holding Alt/Option down, rotate the thin rectangle, let go and that will create a copy.
Once you get enough lines, create a compound path with them.
Select the outer ring and the rectangles that were made into a compound path.
Subtract again.
Release the compound path and each segment can be colored.
