The proposed imaging technique detects speckle patterns to visualize blood circulation in hearts preserved by ex situ heart perfusion (ESHP). Pictured is the schematic showing the imaging process of a heart perfused with nutrients. The proposed optical method utilizes a laser and a camera mounted on an articulated arm to generate and evaluate speckle patterns. The inset image shows the researchers imaging a heart in real time.
