Toward in vivo dosimetry in external beam radiotherapy using x-ray acoustic computed tomography: A soft-tissue phantom study validation
Author(s): Hao Lei, Wei Zhang, Ibrahim Oraiqat, Zhipeng Liu, Jun Ni, Xueding Wang, Issam El Naqa ABSTRACT Purpose: To study, using phantoms made from biological tissues, the feasibility and practical challenges of monitoring the position of the radiation beam and the deposited dose by x-ray acoustic computed tomography (XACT) during external beam radiotherapy delivery. Material and methods: A prototype XACT system […]
FUNCTIONAL PHOTOACOUSTIC IMAGING FOR PLACENTAL MONITORING: A MINI REVIEW
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 mother and […]
WHOLE-BODY HUMAN ULTRASOUND TOMOGRAPHY
Author(s): D. C. Garrett, J. Xu, D. Oh, Y. Aborahama, G. Ku, K. Maslov, W. W. Tseng, and L. V. Wang 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 […]

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, […]
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. Donnelly, Kelsey P. Kubelick, Diego S. Dumani, and Stanislav Y. Emelianov 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, […]
