Cancer Detection and Monitoring with the TriTomTM Photoacoustic imaging has become a popular tool in preclinical cancer research as a noninvasive technique for monitoring tumor growth and therapeutic response. Specifically, photoacoustic imaging can provide high-sensitivity images of both superficial and deep vasculature and quantitative assessment of blood oxygen saturation without exogenous contrast. The TriTom small […]

The development of ionizing radiation acoustic imaging (iRAI) for mapping the dose deep in the patient body during radiation therapy
Author(s): Wei Zhang, Dale Litzenberg, Yaocai Huang, Kai-Wei Chang, Ibrahim Oraiqat, Scott Hadley, Eduardo G. Moros, Man Zhang, Paul L. Carson, Kyle C. Cuneo, Issam EI Naqa, Xueding Wang ABSTRACT Ionizing radiation acoustic imaging (iRAI) provides the potential to map the radiation dose during radiotherapy in real time. Described here is the development of iRAI volumetric imaging system in mapping the three-dimensional (3D) radiation dose deposition […]
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 […]
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 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 in […]
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 […]
