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.

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 […]
DUAL-MODALITY X-RAY-INDUCED RADIATION ACOUSTIC AND ULTRASOUND IMAGING FOR REAL-TIME MONITORING OF RADIOTHERAPY
Authors: Wei Zhang,1 Ibrahim Oraiqat,2 Hao Lei,3 Paul L. Carson,1,4 Issam EI Naqa,2 and Xueding Wang1,4 ABSTRACT Objective. The goal is to increase the precision of radiation delivery during radiotherapy by tracking the movements of the tumor and other surrounding normal tissues due to respiratory and other body motions. Introduction. This work presents the recent advancement of X-ray-induced radiation acoustic imaging (xRAI) […]
IN SITU X-RAY-INDUCED ACOUSTIC COMPUTED TOMOGRAPHY WITH A CONTRAST AGENT: A PROOF OF CONCEPT
Authors: Seongwook Choi,1; Sinyoung Park,1; Ayoung Pyo,2; Dong-Yeon Kim,3 ; Jung-Joon Min,4 ; Changho Lee,4,5,6; Chulhong Kim,1,7 ABSTRACT X-ray-induced acoustic computed tomography (XACT) has shown great potential as a hybrid imaging modality for real-time non-invasive x-ray dosimetry and low-dose three- dimensional (3D) imaging. While promising, one drawback of the XACT system is the underlying low signal-to-noise ratio […]
REAL-TIME, VOLUMETRIC IMAGING OF RADIATION DOSE DELIVERY DEEP INTO THE LIVER DURING CANCER TREATMENT
Authors: Wei Zhang, Ibrahim Oraiqat, Dale Litzenberg, Kai-Wei Chang, Scott Hadley, Noora Ba Sunbul, Martha M. Matuszak, Christopher J. Tichacek, Eduardo G. Moros, Paul L. Carson, Kyle C. Cuneo, Xueding Wang, & Issam El Naqa ABSTRACT Ionizing radiation acoustic imaging (iRAI) allows online monitoring of radiation’s interactions with tissues during radiation therapy, providing real-time, adaptive […]
EVALUATION OF ULTRASOUND SENSORS FOR TRANSCRANIAL PHOTOACOUSTIC SENSING AND IMAGING
Author(s): Thomas Kirchner, Claus Villringer, and Jan Laufer ABSTRACT Significance: Biomedical photoacoustic (PA) imaging is typically used to exploit absorption-based contrast in soft tissue at depths of several centimeters. When it is applied to measuring PA waves generated in the brain, the acoustic properties of the skull bone cause not only strong attenuation but also […]
