An Open-Source Test-Bench for Autonomous Ultrasound Imaging

Due to the need for development of customized transmission, reception, and processing algorithms, low-cost programmable ultrasound imaging devices are desirable for a variety of research applications. This paper describes a programmable 64-channel system-on-chip (SoC)-based test bench for research on autonomous wearable and implantable medical ultrasound imaging. The setup consists of a custom transmitter, a custom high-voltage (HV) multiplexer, an off-the-shelf receiver, and embedded software on the SoC. This results in a modular design that can be easily updated with improved hardware and software for different applications. This paper describes the system design and initial imaging results on tissue phantoms.
