CREANUIS
This page is devoted to 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.
