X-ray-induced acoustic computed tomography (XACT) imaging with single-shot nanosecond x-ray

Autor: Liangzhong Xiang, Siqi Wang, Vassili Ivanov, Prabodh Kumar Pandey

Publikováno v: Appl Phys Lett
Applied physics letters, vol 119, iss 18

X-ray-induced acoustic computed tomography (XACT) has emerged as a promising imaging modality with broad applications in both biomedicine and nondestructive testing. The previous XACT imaging systems require thousands of averages to achieve reasonabl

Preclinical small animal imaging platform providing co-registered 3D maps of photoacoustic response and fluorescence

Autor: Vassili Ivanov, Diego S. Dumani, Mark A. Anastasio, Weylan Thompson, Hans-Peter Brecht, Stanislav Emelianov, Sergey A. Ermilov, Jason R. Cook, Anthony Yu

Publikováno v: Photons Plus Ultrasound: Imaging and Sensing 2019.

We report on the development of a preclinical 3D imaging platform integrating photoacoustic tomography and fluorescence (PAFT). The proposed multimodal imaging concept addresses known deficiencies in sensitivity, anatomical registration, and spatial

Real-time photoacoustic data acquisition with a thousand parallel channels at hundreds frames per second

Autor: Sergey A. Ermilov, Hans Peter Brecht, Vassili Ivanov

Publikováno v: Photons Plus Ultrasound: Imaging and Sensing 2019.

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-

A 3D imaging system integrating photoacoustic and fluorescence orthogonal projections for anatomical, functional and molecular assessment of rodent models

Autor: Sergey A. Ermilov, Mark A. Anastasio, Diego S. Dumani, Vassili Ivanov, Hans Peter Brecht, Stanislav Emelianov

Publikováno v: Photons Plus Ultrasound: Imaging and Sensing 2018.

We have developed a preclinical 3D imaging instrument integrating photoacoustic tomography and fluorescence (PAFT) addressing known deficiencies in sensitivity and spatial resolution of the individual imaging components. PAFT is designed for simultan

Co-registered photoacoustic and fluorescent imaging of a switchable nanoprobe based on J-aggregates of indocyanine green

Autor: Jason R. Cook, Stanislav Emelianov, Justin T. Harris, Sergey A. Ermilov, Kimberly A. Homan, Diego S. Dumani, Vassili Ivanov, Hans-Peter Brecht, Ryan Deschner

Publikováno v: Photons Plus Ultrasound: Imaging and Sensing 2018.

We introduce a preclinical imaging platform – a 3D photoacoustic/fluorescence tomography (PAFT) instrument augmented with an environmentally responsive dual-contrast biocompatible nanoprobe. The PAFT instrument was designed for simultaneous acquisi

MinE recruits, stabilizes, releases, and inhibits MinD interactions with membrane to drive oscillation

Autor: Vassili Ivanov, Mi Li, Kiyoshi Mizuuchi, Anthony G. Vecchiarelli, Michiyo Mizuuchi

SUMMARYThe MinD and MinE proteins ofEscherichia coliself-organize into a standing-wave oscillator on the membrane to help align division at mid-cell. When unleashed from cellular confines, we find that MinD and MinE form a wide spectrum of patterns o
