Abstract EN
In the last few years, Ultrasound Computed Tomography (USCT) techniques has become an attractive and hot research area.
Herein, we present a robust iterative USCT reconstruction algorithm, which based on bent ray theory.
The object to be imaged is encircled by uniformly distributed transduc-ers, whereas one transducer acts as a transmitter and the remains work as receivers.
The travel-time meas-urements can be used to estimate the sound speed distribution by solving a nonlinear system of equations.
Our proposed scheme is based on the straight ray approximation, which is valid for breast ultrasound tomographic imaging.
On this basis, we have formulated a cost function that defines the difference be-tween the measured first arrivals and those calculated for a given velocity model in the least squares sense.
Then, the sound speed image can be obtained by finding the best solution which minimize this dif-ference.
Our method is able to resolve very fine details even in very complex structured objects.
The pre-sented results approve the accuracy and robustness of our approach for breast screening applications
