available on 2024-09-29 Author(s): Vinoin Devpaul Vincely, Carolyn L Bayer ABSTRACT The placenta, a highly vascularized interface between the mother and fetus, undergoes dramatic anatomical and functional changes during pregnancy. These changes occur both during healthy development and adverse pathologies of pregnancy, such as preeclampsia. Abnormal placental development can lead to life-long health impacts on both the […]

WHOLE-BODY HUMAN UTLRASOUND TOMOGRAPHY
ABSTRACT We developed a system for whole-body human ultrasound tomography in reflection andtransmission modes. A custom 512-element ultrasound receiver array with a rotating single-element ultrasound transmitter are used to generate 2D isotropically resolved images across the entire human cross-section. We demonstrate this technique in regions such as the abdomen and legs in healthy volunteers. Compared […]

In the second webinar of the Legion Amp Webinar Series, Samuel Toler (System Test Engineer I), discussed the Legion Amp design, motivation, and benefits in relation to how it could optimize your research. Samuel John and Dr. Yan Yan, from […]
DUAL-MODALITY X-RAY-INDUCED RADIATION ACOUSTIC AND ULTRASOUND IMAGING FOR REAL-TIME MONITORING OF RADIOTHERAPY
This is the third webinar of the Legion AMP webinar series, hosted by PhotoSound Technologies. This webinar covers dual-modality, ultrasound, and thermoacoustic imaging in real-time, while using an ionizing radiation source, for the purpose of monitoring radiation therapy, as presented by Dr. Wei Zhang from the Department of Biomedical Engineering, University of Michigan, Ann Arbor, Michigan, […]
Tissue Engineering & Regeneration
What is Tissue Engineering & Regeneration? Tissue engineering is the process of creating new tissues and organs to replace damaged or diseased tissues. Photoacoustic tomography can be used to evaluate tissue regeneration and vascularization. PhotoSound Product Used TriTom Photoacoustic Image-Guided Delivery of Plasmonic-Nanoparticle-Labeled Mesenchymal Stem Cells to the Spinal Cord MoleculUS A Combined Ultrasound and […]
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 […]
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 […]
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 […]
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, […]
