Author(s): Zohar Or, Ahiad R. Levi, Yoav Hazan and Amir Rosenthal ABSTRACT he ability to rapidly locate blood vessels in patients is important in many clinical applications, e.g., in catheterization procedures. Optical techniques, including visual inspection, generally suffer from a reduced performance at depths below 1 mm, while ultrasound and optoacoustic tomography are better suited […]

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 […]
Nanosecond Pulsed Light Emitting Diode (LED) Based High-Speed Photoacoustic Computed Tomography Using Multiple Single-Element Ultrasound Transducers
Author(s): Avishek Das, Manojit Pramanik ABSTRACT Light-emitting diodes (LEDs) emerge as a viable alternative to pulsed lasers in photoacoustic computed tomography (PACT) due to their low cost, compact form factor, wavelength flexibility, and reduced safety concerns. Unlike class-IV laser systems, LED-based excitation eliminates regulatory constraints while enabling high pulse-repetition rates (PRRs) and flexible modulation for […]

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 […]
A COMBINED ULTRASOUND AND PHOTOACOUSTIC IMAGING PLATFORM FOR CLINICAL RESEARCH APPLICATIONS
Author(s): Weylan Thompson, Hans-Peter Brecht, Sergey A. Ermilov, Vassili Ivanov ABSTRACT We present the continued development of a clinical ultrasound (US) imaging device with a photoacoustic (PA) mode. The combined USPA imaging platform is designed around a compact US component capable of B-mode, M-mode, color Doppler, and pulsed wave Doppler US imaging modes with a 128-element US probe. […]
A PRECLINICAL SMALL ANIMAL IMAGING PLATFORM COMBINING MULTI-ANGLE PHOTOACOUSTIC AND FLUORESCENCE PROJECTIONS INTO CO-REGISTERED 3D MAPS
Authors: Weylan Thompson, Anthony Yu, Diego S. Dumani, Jason Cook, Mark A. Anastasio, Stanislav Y. Emelianov, Sergey A. Ermilov ABSTRACT We present the results on development of the 3D imaging platform combining photoacoustic tomography and fluorescence (PAFT) for preclinical and biological research. This combined multimodal imaging instrument addresses known deficiencies in sensitivity, spatial resolution, and […]
PRECLINICAL SMALL ANIMAL IMAGING PLATFORM PROVIDING CO-REGISTERED 3D MAPS OF PHOTOACOUSTIC RESPONSE AND FLUORESCENCE
Authors: Diego S. Dumani1,2, Anthony Yu1,2, Weylan Thompson3, Hans-Peter Brecht3, Vassili Ivanov3, Mark A. Anastasio4, Jason Cook5, Sergey A. Ermilov3, Stanislav Y. Emelianov1,2 ABSTRACT We report on the development of a preclinical 3D imaging platform integrating photoacoustic tomography and fluorescence (PAFT). The proposed multimodal imaging concept addresses known deficiencies in sensitivity, anatomical registration, and spatial […]
