Laser, sound waves provide live views of organs in action

Biomedical engineers are now able to take a live, holistic look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells and firing neural networks. The technique uses the best of both light and ultrasound, breaking long-standing resolution and speed barriers in small-animal whole-body imaging, providing full cross-sectional view of a small animal’s internal functions in real-time.
