Simulations of carbon-fiber-reinforced plastics (CFRP) using the finite element method in electromagnetic tomography nondestructive evaluation systems are presented in this paper. Ansoft Maxwell 3D models describing the interaction of the sensors with both unidirectional and cross-woven plate samples are built and analyzed to show the CFRP orientations. A circular sensors array is designed and 400...
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...
