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 […]

Cancer Imaging
What is Cancer Imaging? Cancer imaging: In applications related to cancer, photoacoustic tomography has been used to noninvasively monitor tumor size, evaluate tumor metastasis, and detect the response to novel cancer therapies. PhotoSound Product Used TriTom Water-Soluble Fe(II) Complexes for Theranostic Application: Synthesis, Photoacoustic Imaging, and Photothermal ConversionCo-registered photoacoustic and fluorescent imaging of a switchable nanoprobe […]
Contrast Agent Development
What is Contrast Agent Development? Photoacoustic contrast agents, such as indocyanine green (ICG), are used to enhance the visibility of specific targets within a subject and targeting to investigate specific molecular markers. PhotoSound Product Used TriTom In situ x-ray-induced acoustic computed tomography with a contrast agent: a proof of concept Biodegradable and biocompatible semiconductor nanocrystals […]

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. Dumani, Hans-Peter Brecht, Vassili Ivanov, Ryan Deschner, Justin T. Harris, Kimberly A. Homan, Jason R. Cook, Stanislav Y. Emelianov, Sergey A. Ermilov 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

COMMERCIAL SMALL ANIMAL IMAGING COULD AID DISEASE DETECTION
Authors: Mark Little ABSTRACT The development of anticancer metastatic therapies for human clinical trials requires meticulous evaluation of efficacy and optimization of small animal test models in preclinical experimentation. Critical information on morphology and the molecular microenvironment of tumors is currently obtained and monitored using noninvasive, in vivo imaging methods. Detection of individual, small tumors […]
