Neuroimaging
What is Neuroimaging? Neuroimaging is the use of medical imaging techniques to study the structure and function of the nervous system, focusing on the brain. Photoacoustic tomography has been used to image the brain, spinal cord, and other parts of the nervous system. PhotoSound Product Used TriTom Monitoring Neonatal Brain Hemorrhage Progression by Photoacoustic Tomography […]
Anatomical Imaging
What is anatomical imaging? Anatomical imaging is used to visualize the structure and organization of tissues and organs within the body. Photoacoustic tomography generates high-resolution images of blood-rich tissues without the need for exogenous contrast agents. PhotoSound Product Used TriTom Dual-Scan Photoacoustic Tomography for the Imaging of Vascular Structure on Foot Photoacoustic tomography to assess […]

REAL-TIME PHOTOACOUSTIC DATA ACQUISITION WITH A THOUSAND PARALLEL CHANNELS AT HUNDREDS FRAMES PER SECOND
Authors: Vassili Ivanov, Hans Peter Brecht, Sergey A. Ermilov AFFILIATIONS PhotoSound Technologies, Inc. (United States) ABSTRACT Large number of simultaneously acquired spatially distinct pressure signals is required to improve quality of real-time photoacoustic and x-ray acoustic biomedical images [1]. In the past this approach was limited by availability of commercial multi-channel analog-to-digital converter (ADC) systems […]
CO-REGISTERED PHOTOACOUSTIC AND FLUORESCENT IMAGING OF A SWITCHABLE NANOPROBE BASED ON J-AGGREGATES OF INDOCYANINE GREEN
Authors: Diego S. Dumani1,2, Hans-Peter Brecht3, Vassili Ivanov3, Ryan Deschner4, Justin T. Harris4, Kimberly A. Homan4, Jason R. Cook5, Stanislav Y. Emelianov1,2, Sergey A. Ermilov3 ABSTRACT We introduce a preclinical imaging platform – a 3D photoacoustic/fluorescence tomography (PAFT) instrument augmented with an environmentally responsive dual-contrast biocompatible nanoprobe. The PAFT instrument was designed for simultaneous acquisition […]
MASSIVE PARALLEL ULTRASOUND AND PHOTOACOUSTIC PC-BASED SYSTEM
Authors: Weylan Thompson, Hans Peter Brecht, Sergey Ermilov, Vassili Ivanov ABSTRACT PhotoSound Technologies specializes in the development of electronics solutions for massive parallel data acquisition applicable to the fields of photoacoustics (PA), X-ray acoustics, including 3D dosimetry, and ultrasound. PhotoSound’s Legion ADC256 R1.1, released in 2018, is a 256-channel 12-bit ADC with a sampling rate […]
A PRECLINICAL SMALL ANIMAL IMAGING PLATFORM COMBINING MULTI-ANGLE PHOTOACOUSTIC AND FLUORESCENCE PROJECTIONS INTO CO-REGISTERED 3D MAPS
Authors: Weylan Thompson1, Anthony Yu2,3, Diego S. Dumani2,3,4, Jason Cook5, Mark A. Anastasio6, Stanislav Y. Emelianov2,3, Sergey A. Ermilov1 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 […]
PHOTOACOUSTIC IMAGE-GUIDED DELIVERY OF PLASMONIC-NANOPARTICLE-LABELED MESENCHYMAL STEM CELLS TO THE SPINAL CORD
Authors: Eleanor M. Donnelly1, Kelsey P. Kubelick2, Diego S. Dumani1,2, and Stanislav Y. Emelianov1,2 ABSTRACT Regenerative therapies using stem cells have great potential for treating neurodegenerative diseases and traumatic injuries in the spinal cord. In spite of significant research efforts, many therapies fail at the clinical phase. As stem cell technologies advance toward clinical use, […]
TECHNICAL CONSIDERATIONS IN THE VERASONICS RESEARCH ULTRASOUND PLATFORM FOR DEVELOPING A PHOTOACOUSTIC IMAGING SYSTEM
Authors: Karl Kratkiewicz1,4,Rayyan Manwar2,4, Yang Zhou, Moein Mozaffarzadeh3, Kamran Avanaki2 ABSTRACT Photoacoustic imaging (PAI) is an emerging functional and molecular imaging technology that has attracted much attention in the past decade. Recently, many researchers have used the vantage system from Verasonics for simultaneous ultrasound (US) and photoacoustic (PA) imaging. This was the motivation to write […]
