— Lihong Wang, Professor at Washington University in St. Louis, is a pioneer in the field of Photoacoustic (PA) Imaging. His innovations have enabled non-invasive imaging of living organisms at scales ranging from subcellular to whole-body at depths and resolutions that are simply impossible with any …
— The invention is a novel photoacoustic imaging technique, termed reversibly switchable photoacoustic tomography (RS-PAT). It exhibits a large penetration depth, a high detection sensitivity, and a spatial super-resolution. The most important feature of this technique is that it significantly incre…
— In clinical practice, high imaging speed is critical to reduce motion artifacts, cost, and patient discomfort. Researchers at Washington University have developed multi-focal optical-resolution photoacoustic microscopy (MFOR-PAM) capable of high-resolution imaging of hemoglobin concentration and oxy…
— Optical coherence tomography (OCT) utilizes optical light to obtain an image of opaque or translucent objects, ie tissue. Because scattered light contributes to the bluring found in other optical imaging techniques, OCT filters out all the scattered light. An image is formed using only the back refl…
— A photoacoustic tomography device that provides high optical absorption contrast with high lateral resolution, including very good melanin distribution images, for port wine stain birthmarks.
— Photon tunneling has the potential to guide light to the core of a human body in vivo. Imaging, sensing, and therapy are among the applications for this technology. Light, as opposed to potentially harmful x-rays, is an ideal non-ionizing radiation for imaging and treating biological tissue, however…
