Author(s): Weiran Pang, Bowen Zhu, Honghui Li, Yingying Zhou, Chi Man Woo, Xiazi Huang, Tianting Zhong, Hsuan Lo, Laiyou Wang, Puxiang Lai, Liming Nie GRAPHICAL ABSTRACT This work proposes a novel method for monitoring deep-brain electrodynamics with a voltage-sensitive dye (VSD)-based photoacoustic imaging platform, called PA-VSD. This platform is demonstrated to allow for effectively localizing epileptic foci and visualizing voltage conduction pathways in a high spatiotemporal […]

3D Frequency-Domain Full Waveform Inversion for Whole-Breast Imaging With a Multi-Row Ring Array
Author(s): Rehman Ali, Gaofei Jin, Melanie Singh, Trevor Mitcham, Nebojsa Duric ABSTRACT For ring-array ultrasound tomography, two-dimensional frequency-domain full waveform inversion is the clinical gold standard for high-resolution imaging of the breast. While yielding high-resolution images in the plane of the ring-array, the resulting slice-wise approach yields lower resolution out of plane when used to reconstruct […]
Enhanced clinical photoacoustic vascular imaging through a skin localization network and adaptive weighting
Author(s): Chuqin Huang, Emily Zheng, Wenhan Zheng, Huijuan Zhang, Yanda Cheng, Xiaoyu Zhang, Varun Shijo, Robert W. Bing, Isabel Komornicki, Linda M. Harris, Ermelinda Bonaccio, Kazuaki Takabe, Emma Zhang, Wenyao Xu, Jun Xia ABSTRACT Photoacoustic tomography (PAT) is an emerging imaging modality with widespread applications in both preclinical and clinical studies. Despite its promising capabilities to provide high-resolution images, the […]
Utility of Low-Cost Multichannel Data Acquisition System for Photoacoustic Computed Tomography
Author(s): Zafar, Mohsin, Rayyan Manwar, Seyed Mohsen Ranjbaran, and Kamran Avanaki ABSTRACT Typically, multi-single-element photoacoustic computed tomography (PACT) systems utilize numerous ultrasound transducers arranged in cylindrical or hemispherical configurations for detection, combined with a single diffuse light source or multiple sparse light sources to illuminate the imaging target. While these systems produce high-quality 3D PA images, […]
Signal-domain speed-of-sound correction for ring-array-based photoacoustic tomography
Author(s): Daohuai Jiang, Hengrong Lan, Shangqing Tong, Xianzeng Zhang, Fei Gao ABSTRACT Photoacoustic imaging combines the advantages of optical and acoustic imaging, making it a promising tool in biomedical imaging. Photoacoustic tomography (PAT) reconstructs images by solving the inverse problem from detected photoacoustic waves to initial pressure map. The heterogeneous speed of sound (SoS) distribution in biological tissue significantly affects […]

Investigating the Impact of Chronical Prenatal Alcohol Exposure on Fetal Vascular Development Across Pregnancy Stages Using Photoacoustic Tomography
Author(s): Hao Yang, Md Farhan Tanvir, Huabei Jiang Graphical Abstract This study investigates the effects of chronic prenatal alcohol exposure on fetal brain vascular development in mice using photoacoustic tomography. Key vascular parameters such as vessel diameter, density, and oxygen saturation were analyzed from embryonic Days 10 to 20. Results demonstrate significant vascular disruptions in alcohol-exposed […]
Rotational ultrasound and photoacoustic tomography of the human body
Author(s): Yang Zhang, Shuai Na, Jonathan J. Russin, Karteekeya Sastry, Li Lin, Junfu Zheng, Yilin Luo, Xin Tong, Yujin An, Peng Hu, Konstantin Maslov, Tze-Woei Tan, Charles Y. Liu, Lihong V. Wang ABSTRACT Imaging the human body’s morphological and angiographic information is essential for diagnosing, monitoring, and treating medical conditions. Ultrasonography performs the morphological assessment of […]
