The various work I particpate around the passive cavitation imaging as produce numerous code. In particular, the cross matrix fitting based on total variation has been released though a git repertory. The information can be found here.
 

CREANUIS

This section is a quick presentation of the Creanuis software. This software allows to simulate the nonlinear ultrasound radio frequency (RF) images obtained with linear sources. Indeed, Creanuis software couples two different approaches:
  • A nonlinear prpagation field simulator, based on a generalized angular spectrum approach method [1]
  • An image reconstruction scheme, using the nonlinear produced fields [2]
The design of the GASM also allow to simulate inhomogeneous medium in term of coefficient of nonlinearity and new types of RF images are obtained. The CREANUIS software has been developed in C/C++. The different proposed version of the software can be downloaded hereafter.
