Body text

PBI (Propagation-Based Imaging, also known as Refraction-Enhanced Imaging) provides an image based on a stepwise change in the refractive index in a material. In biological samples, it is especially powerful to visualize boundaries between air and a tissue, and those between bone and soft tissue. The images below show the process of aeration of the lung of a newborn rabbit (from left, fetal, after 12 breaths, after 1 hour). This is a unique method to directly observe air in the lung at high resolution.
