Our laboratory's mission to attain a nuanced appreciation of physiological and pathological phenomena hinges on the ability to perform non-invasive, three-dimensional imaging across opaque tissues. This approach spans various spatial and temporal dimensions, thereby revealing the complex tapestry of intercellular interactions at the organ level. Despite its potential, this methodology faces formidable obstacles such as vast data throughput requirements, optical heterogeneity, surface irregularity, and phototoxic effects. These challenges necessitate a delicate balance between volume size, resolution, speed, sample vitality, and system complexity.

To surmount these barriers, we have integrated advances in computational optics, biological engineering, and machine learning to develop a suite of pioneering tools that enhance the capacity of intravital imaging. Notably, our RUSH technology achieves over a centimeter field of view (FOV) with single-cell resolution. The RUSH3D variant extends these capabilities into three-dimensional space, while RUSH-mini condenses this technology into a compact form factor weighing less than three grams, suitable for studies involving freely moving animals.

These innovations find wide applicability in the fields of neuroscience, immunology, and pathology, positioning our team's contributions as versatile instruments for the mesoscale examination of intricate biological systems, ranging from individual cells to complex organ structures.
