Abstract
Portable LED-based systems attempt to replace the bulky laser-based photoacoustic (PA) systems. The problem with LEDs is their low energy which generates low signal-to-noise-ratio (SNR) images. To obtain a high SNR image in real-time, we built a deep learning U-net model which transforms a low no. of frame-averaged image into a high no. of frame-averaged quality image. Both laser-based Vevo LAZR-X system and immunofluorescence histology staining show similar vascular organizations with hypoxic cores. We also achieved high SNR by running the algorithm on acoustic-resolution PA microscopy captured images. This generic network can be implemented in multiple scenarios.
