Abstract :
2D Shepp-Logan head model is the classical model of simulations in 2D medical image reconstruction of CT. A method, considering 3D Shepp-Logan head model as the reference model of simulations in 3D medical image reconstruction of spiral CT, is proposed in the paper. Designing of 3D Shepp-Logan head model as well as computing of the projection data is introduced, and then the simulation for 3D medical image reconstruction of spiral CT based on 3D Shepp-Logan head model is presented. The experimental results indicate the accuracy of the model computing, and the feasibility and validity of the method.
