An overall protocol for super-resolution ultrasound imaging with optically triggered perfluorohexane nanodroplets (PFHnDs). Thresholded images in the third row are binary images (green for zero and yellow for one) and the sparse isolated droplets, which do not have any other droplets located closely, are shown with white squares.
