Description
Summary:The design and development of an open and flexible ultrasonic imaging system based on a high performance computer architecture is presented in this work. The system exploits the different forms of intrinsic parallelism frequently associated to the process of ultrasonic imaging creating a flexible, modular and scalable test-bed for the implementation of existing methods and the development of new hardware architectures and processing algorithms. Transmission beam focusing, scanning techniques and efficient interpolation schemes are developed and applied in order to increase the spatial resolution of the constructed ultrasonic images. The algorithms are assessed and implemented in order to achieve a real-time response, a key goal in ultrasonic image applications. The flexibility and scalability characterised by the system allow to incorporate new developments in technology and to utilise more complex algorithms for improving the images visual appearance in real-time.
