Photoacoustic Tomography (PAT) is a recently discovered medical imaging modality that combines the benefits of pure optical and ultrasonic images with strong optical contrasts and great depth of penetration. Deep Learning (DL), a novel paradigm, has attracted much interest recently due to its capability to enhance medical imaging. Similarly, DL is commonly employed in Photo Acoustic Imaging (PAI) to address some of the constraints of PAI. In photoacoustic imaging, traditional reconstruction algorithms such as delay-and-sum were extensively utilized. Recent experiments have shown that deep neural networks can reconstruct PAI from unprocessed photoacoustic data. This paper provides a modified fuzzy-based CNN-BiLSTM architecture as a foundation for a neural network to tackle PAI image reconstruction with Modified Particle swarm optimization (MFCB-PS). The numerical simulation results reveal that the suggested frameworks outperform standard reconstruction approaches significantly. Furthermore, the suggested reconstruction technique surpasses existing standard reconstruction algorithms regarding time consumption, indicating its potential for real-time image analysis.
