Short Description
Ultrasound imaging is an important biomedical technique for analyzing soft tissues in the human body, with both diagnostic and therapeutic applications. IIS is involved in a project developing a high-performance, portable 3D ultrasound platform.
The basic principle of ultrasound imaging is to excite the target body with high-frequency acoustic pulses and to form an image using the back-reflected echoes. The reconstruction of the image based on these echoes is called beamforming and for today's 2D transducer heads with several thousand transducer elements, it is definitely the computationally most intensive operation. In order to allow for portable 3D ultrasound systems, new algorithms and hardware architectures for digital beamforming are currently being developed at IIS.
The goal of this semester project is the optimization and ASIC implementation of a single or a few processing channels of a high-channel-count beamformer for 3D ultrasound imaging. In order to do an accurate design feasibility study of the complete beamformer architecture, the fabricated ASIC is tested, measured and physically characterized in a second phase.
