A MATLAB GUI Interface for Multi-Level Pulse Amplitude Modulation (PAM) Generation in Medical Ultrasound Research

Abstract

The development and evaluation of novel medical ultrasound imaging methods based on advanced pulse encoding techniques typically requires the generation of complex excitation waveforms. To meet this need, reconfigurable FPGA-based systems have been used to control multi-level high voltage pulse generators, such as the MD2134 driver (Microchip Technology Inc.). In this paper, we present a flexible Matlab GUI (Graphical User Interface) application to simulate complex analog waveforms and automatically generate FPGA code to control the MD2134 chip using the Pulse Amplitude Modulation (PAM) technique.
