An imaging method developed by researchers at the University of St. Andrews aims to overcome difficulties in analyzing and imaging the beating heart. Researchers integrated tiny lasers into heart muscle cells of live zebra fish to acquire high-resolution measurements of their contractility. The method allowed them to perform the measurements at locations several times deeper than with other light-based techniques.
Obtaining images and analyses of the beating heart is difficult due to the constant motion of living tissue. The dense muscle fibers of the heart tend to strongly scatter and absorb light. While advanced microscopy methods such as multiphoton imaging are able to see up to 1 mm into the brain, the challenging environment of…READ MORE
