Author(s): A. M. Yu, X. Huang, S. M. A. Morais, J. H. Park, D. A. Zopf, S. J. Hollister, and S. Emelianov ABSTRACT Craniofacial implants are prone to skin necrosis and exposure, likely due to implant-induced stress and ischemia. However, this relationship has not been quantitatively validated. Identifying an imaging biomarker of skin vascular health […]

Dual photoacoustic/ultrasound technologies for preclinical research: current status and future trends
Author(s): M. Pérez-Liva, M. Alonso de Leciñana, M. Gutiérrez-Fernández, J. Camacho Sosa Dias, J. F. Cruza, J. Rodríguez-Pardo, I. García-Suárez, F. Laso-García, J. L. Herraiz, and L. Elvira Segura ABSTRACT Photoacoustic (PA) imaging, by integrating optical and ultrasound (US) modalities, combines high spatial resolution with deep tissue penetration, making it a transformative tool in biomedical […]
Direct Monitoring of Whole-Brain Electrodynamics via High-Spatiotemporal-Resolution Photoacoustics with Voltage-Sensitive Dye
Author(s): W. Pang, B. Zhu, H. Li, Y. Zhou, C. M. Woo, X. Huang, T. Zhong, H. Lo, L. Wang, P. Lai, and L. Nie 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 […]
3D Frequency-Domain Full Waveform Inversion for Whole-Breast Imaging With a Multi-Row Ring Array
Author(s): R. Ali, G. Jin, M. Singh, T. Mitcham, and N. Duric Comparison of 2D slicewise to 3D FWI with simulated multi-row ring array. Cylindrical wave transmits from a multi-row ring-array (32 rows; 256 elements per row; 22 cm diameter; 2.4 mm between rows) were simulated in three different numerical breast phantoms. Orthographic slice views […]
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 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 groups […]
