Abstract
The application of a step function increase in acoustic pressure during ultrasound imaging using gas vesicle contrast, along with capturing successive frames of ultrasound imaging and extracting time-series vectors for pixels of the frames, allows for improved imaging down to even the cell level. Template vectors can be used to implement signal separation of the time-series vectors to improve detection.
