Advances in photoacoustic imaging reconstruction and quantitative analysis for biomedical applications
Photoacoustic imaging (PAI) is rapidly transitioning from preclinical research to clinical practice, offering high-contrast optical imaging with deep ultrasound penetration. This review highlights three primary implementations: photoacoustic computed tomography (PACT), photoacoustic microscopy (PAM), and photoacoustic endoscopy (PAE), analyzing their advantages and limitations. Recent advancements in image reconstruction, including conventional and deep learning (DL)-based approaches, are crucial for enhancing image quality and streamlining workflows. The review also explores progress in quantitative PAI for measuring physiological biomarkers like hemoglobin concentration and oxygen saturation. Emerging trends, particularly the transformative potential of DL, are outlined for shaping PAI's clinical evolution.

DL in PACT Image Reconstruction
Deep learning models significantly enhance Photoacoustic Computed Tomography (PACT) by improving image quality, suppressing artifacts, and accelerating reconstruction times. For instance, studies show SSIM and PSNR improvements of up to 0.65 and 5.1 dB over traditional methods like Delay-and-Sum (DAS), even with as few as 32 projections. This translates to high-fidelity 3D images with reduced computational resources.
Impact: Enabled high-quality 3D PACT images from sparse data, achieving significant improvements in structural similarity and peak signal-to-noise ratio, accelerating clinical adoption.
