a Schematic drawing of setups for vortex flow measurement. Two example frames are shown in the right. b Comparison of the flow field in the x-z plane at −5 mm, 0 mm, and 5 mm reconstructed by refocusing algorithm and RTU-Net. Blue dashed circles label a vortex, which was recovered by RTU-Net, but not recovered by conventional method. c The streamline obtained with refocusing algorithm and RTU-Net
