CREASIMUS: a fast simulator of ultrasound image sequences using 3D tissue motion

Ultrasound simulated data are often used for validation of processing algorithms. Simulation methods in medical ultrasound are based on an acoustical approach or a system approach. In this article, we present a simulator derived from the well-known system approach because of its low complexity. The simulator was developed using VTK and ITK libraries and computes then displays 4 images/second. Besides, it is divided into four tabs dedicated to selection of simulation parameters, visualization of RF/envelope data and save of simulated sequence. The user can define several parameters such as the emitting central frequency, the standard deviations of the PSF, the size of images or the displacement field between images.
