Custom Systems & Algorithms

PhotoSounds OEM Line of products is an ideal starting point for the development of custom systems where the parallel acquisition of multiple channels is required. All our ADCs are streaming and allow the continuous acquisition of data straight to the receiving computer for processing or storage. PhotoSound’s ADCs are feature-rich, they have multiple electronic and […]

GPU-Accelerated 3D Volumetric X-Ray-Induced Acoustic Computed Tomography

Author(s): Donghyun Lee, Eun-Yeong Park, Seongwook Choi, Hyeongsub Kim, Jung-joon Min, Changho Lee, and Chulhong Kim ABSTRACT X-ray acoustic imaging is a hybrid biomedical imaging technique that can acoustically monitor X-ray absorption distribution in biological tissues through the X-ray induced acoustic effect. In this study, we developed a 3D volumetric X-ray-induced acoustic computed tomography (XACT) […]

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 […]

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 […]

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 […]

DEEP LEARNING ENABLED REAL-TIME PHOTOACOUSTIC TOMOGRAPHY SYSTEM VIA SINGLE DATA ACQUISITION CHANNEL

Author(s): Hengrong Lan, Daohuai Jiang, Feng Gao, Fei Gao ABSTRACT Photoacoustic computed tomography (PACT) combines the optical contrast of optical imaging and the penetrability of sonography. In this work, we develop a novel PACT system to provide real-time imaging, which is achieved by a 120-elements ultrasound array only using a single data acquisition (DAQ) channel. To reduce the channel number of DAQ, we superimpose 30 nearby […]
