N2 - Head motion during brain CT studies can degrade the reconstructed image through distortion and other artifacts such as blurring, doubling and thereby contributing to misdiagnosis of diseases. Estimation of motion parameters is essential for mitigating motion artifacts. In this paper, we propose a marker based numerical optimization method to measure six degrees of freedom of head motion in three-dimensional cone-beam CT system without using any external motion sensors. Simulation results demonstrate that our method has prerequisite accuracy, linearity and range compared to the existing external sensor based method.
