Portable Ultrasound Data Acquisition System Design.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Ultrasound is radiation-free, patient-friendly and less expensive when compared to other medical imaging techniques. Ultrasound scanning has the capability to image the organs in real time, thus offering quick diagnosis. Conventional medical ultrasound machines are not suited for remote health monitoring because of their large form factor and lack of trained sonographers limiting its use only to urban areas and well trained clinicians. This thesis discusses the implementation of portable ultrasound data acquisition system for Point of Care (POC) applications in both of the system-level Hardware and Firmware design level. In the Hardware design, we are targeting the compact able application as well as the extendable applications where the power, level of integration and the
feasible of the replication are critical. The portable system architecture for 8-channel consists of ASICs for ultrasound and FPGA. Beam forming is the front end process to steer and focus the acoustic beam with in the region of interest for diagnosis.
