The total gantry rotation is the sum of all
red angles
(counter-clockwise)
and all
green angles
(clockwise).
The sum of all
red angles
is 360 degrees.
The maximum gantry rotation angle is 360 degrees
plus the sum of all concavities
Courstesy of Markus Alber
What is the maximum gantry rotation angle needed
to paint all gradients for this target??
