Cost-efficient and multi-functional systems for ultrasound measurement and imaging

Austin J Biomed Eng. 2014;1(1):1001.


Two cost-efficient systems were designed and demonstrated for reconstructing ultrasound wave propagation and interference and for understanding the principles of ultrasound imaging and microbubble-enhanced ultrasound imaging. One of the systems was based on a needle hydrophone that was mechanically scanned in an ultrasound focal zone, and the other system was based on a metal wire or needle, with a small diameter, that was translated in an ultrasound focal zone. The advantages and disadvantages of both methods were discussed. These systems are useful for students, educators, and researchers for investigating ultrasound wave properties and understanding ultrasound imaging principles when the budget is limited.
