Development of Dynamics and Control Simulator for Mobile CT Device and Its Implementation

This paper presents development of simulators for mobile CT device. For mobile CT device, it is important to rotate the gantry system at constant speed. Rotating a gantry speed at constant speed is important because uniformity of angular distance among hundreds of taken X-ray images is highly related to quality of 3D reconstructed CT image. Therefore, in this paper, modeling of the gantry system and simulator is developed for control verification. Mobile CT device is a heavy system so it has a safety issues for engineer. Hence, it is preferred to develop a simulator which is really close to the real system. Then, implementation of the system will be easier after verification of the system using a simulator. The simulator which verifies control algorithm and sequence is presented using Lab view and Solid works and it can be implemented to the real system directly.
