Model nonlinear effect in ultrasound fields
Kulík, Tomáš ; Čech, Petr (referee) ; Rozman, Jiří (advisor)
The main topic of this diploma thesis is the modeling of nonlinear effects in ultrasonic fields. The work deals with application of finite difference method (FDTD) on the Westervelt equation and the subsequent creation of the model of ultrasonic fields in MATLAB. This thesis also includes theoretical analysis of ultra-acoustic and technical aspects of diagnostic ultrasonography. In addition, this document includes verification of theoretical assumptions by using created model.

Design of ultrasound probe focusation algorithm.
Maceška, Radek ; Rozman, Jiří (referee) ; Čech, Petr (advisor)
This thesis deals with electronic focusing of ultrasonic probes. There is theoretically described, what is the electronic focusing. Further, there are calculations that are used to achieve focusing. These calculations are then implemented into the algorithm that was developed in Matlab. The paper also contains the simulation conducted using the proposed algorithm and the GUI. These simulations are then compared with characteristics measured on a real ultrasound probe.
