| Description | USCT-sim is a fast simulation tool for ultrasound transmission tomography systems. It is written in Matlab and based on following approximations: * Discretization of the simulated volume -- the volume describing the shape and material properties of the depicted phantom is discretized into regular voxels (cubes) representing areas with homogeneous material properties. * Straight propagation -- the ultrasonic pulses are modeled along straight line between sending and receiving transducer assuming a spherical wave. * Transducer characteristics -- the shape and size of the transducers is neglected in the simulation, however the effects the heterogeneous radiation characteristic of the transducers can be defined by the user as a function of angle-dependent frequency response. * Scattering effects -- to simulate the reflection/scattering effects the volume is filled with large number of scattering points and the propagation of the ultrasonic pulse is computed for the first-order scattering paths (sender-scatterer-receiver). |
