    • Abstract
  • Rotation Center Determination is one of the basic problems in CT system integration.This paper proposed an automatic method to decide rotation center by Hough Transform with thin cylinder phantom.Hough Transform can provide position and radius of cylinder and also the difference of actual radius of cylinder,the radius of the cylinder,and the difference of the actual radius of the cylinder.With this difference,we can determine the rotation center of CT system.
