Abstract
Functional imaging and super-resolution imaging are promising research areas of medical ultrasound. For the purpose of tracking physiological changes and micro-bubbles, they require continuous data acquisition for minutes. One flexible and mobile research scanner that can be used for that purpose is the Verasonics Vantage, which however has a hardware limitation of approximately 132,000 emissions per data acquisition using the stock software library. Using an emission rate of 5 kHz gives an acquisition time of only 26 seconds, which is insufficient. This paper presents a technique for overcoming this limitation, achieving long acquisitions where the scan duration is limited by the computer RAM only. The technique has been already routinely used for 10-minute in-vivo scans of exposed rat kidneys, resulting in micro-bubble tracking maps for super-resolution imaging.
