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) […]

Spatiotemporal Image Reconstruction to Enable High-Frame-Rate Dynamic Photoacoustic Tomography with Rotating-Gantry Volumetric Imagers

Author(s): Refik Mert Cam, Chao Wang, Weylan Thompson, Sergey A. Ermilov, Mark A. Anastasio, Umberto Villa ABSTRACT Significance Dynamic photoacoustic computed tomography (PACT) is a valuable imaging technique for monitoring physiological processes. However, current dynamic PACT imaging techniques are often limited to two-dimensional spatial imaging. Although volumetric PACT imagers are commercially available, these systems typically employ a rotating measurement gantry […]

Water-Soluble Fe(II) Complexes for Theranostic Application: Synthesis, Photoacoustic Imaging, and Photothermal Conversion

Authors: Maeva Delcroix, Dr. Anil Reddy Marri, Stéphane Parant, Dr. Philippe C. Gros, Dr. Mathilde Bouché ABSTRACT Significant effort focused on developing photoactivatable theranostics for localized image guided therapy of cancer by thermal ablation. In this context iron complexes were recently identified as photoactivatable theranostic agents with adequate biocompatibility and body clearance. Herein, a series of FeII complexes bearing polypyridine […]

LIVE PRODUCT DEMONSTRATION AT THE PHOTOSOUND BOOTH 8539 DURING THE BiOS EXHIBITION

Visit the PhotoSound’s booth #8539 to meet our Production Manager, Sam Toler. Sam will have live product demonstrations featuring the MoleculUSTM, our dual-modality ultrasound and photoacoustic data acquisition unit that allows the simultaneous collection of ultrasound and photoacoustic channels sharing the same probe elements. The MoleculUSTM can use linear, convex, and endocavitary handheld probes. Stop by […]

Model-Based 3-D X-Ray Induced Acoustic Computerized Tomography

Authors: Prabodh Kumar Pandey; Siqi Wang; Leshan Sun; Lei Xing; Liangzhong Xiang ABSTRACT X-ray-induced acoustic (XA) computerized tomography (XACT) is an evolving imaging technique that aims to reconstruct the X-ray energy deposition from XA measurements. Main challenges in XACT are the poor signal-to-noise ratio and limited field-of-view, which cause artifacts in the images. We demonstrate the efficacy of model-based […]

Discrete Wavelet Transformation for the Sensitive Detection of Ultrashort Radiation Pulse with Radiation-Induced Acoustics

Authors: Rick Van Bergen, Leshan Sun, Prabodh Kumar Pandey, Siqi Wang, Kristina Bjegovic, Gilberto Gonzalez, Yong Chen, Richard Lopata, Liangzhong Xiang ABSTRACT Radiation-induced acoustics (RIA) shows promise in advancing radiological imaging and radiotherapy dosimetry methods. However, RIA signals often require extensive averaging to achieve reasonable signal-to-noise ratios, which increases patient radiation exposure and limits real-time […]

X-Ray Acoustics

What is X-Ray Acoustics? X-Ray Acoustics is the conversion of pulsed X-rays into sound waves. The interaction of X-rays and tissue is weaker than that of optical light which allows for deep penetration. However, the same weak interaction is greatly reducing contrast. The long pulse duration of X-ray sources limits the spatial resolution of X-ray […]
