Quantitative Fluorescence Photoacoustic Tomography

SIAM Journal on Imaging Sciences, 2013
Fluorescence photoacoustic tomography (fPAT) is a multimodality biomedical imaging technique that combines high-resolution ultrasound imaging with high-contrast fluorescence optical tomography. In the first step of fPAT, one utilizes the photoacoustic effect to recover the total absorbed energy map inside the media with ultrasound tomography.

Photoacoustic Tomography of the Brain

, 2012
Photoacoustic tomography (PAT) is an emerging hybrid imaging technique with great potential for a wide range of brain imaging applications. A unique feature of PAT is the capability of sensing optical contrasts ultrasonically. Because of the low ultrasonic scattering in tissue, PAT generates high resolution images in both the ballistic and diffusive ...

Photoacoustic Tomography

2021
Photoacoustic tomography (PAT) is an imaging technique that depicts optical absorbers in biological tissues with acoustic resolution. Compared to photoacoustic microscopy (PAM), PAT images several centimeters deep with a spatial resolution of several hundred micrometers.

Photoacoustic Tomography for Imaging Nanoparticles

2010
Nanotechnology is the key to a new, noninvasive photoacoustic imaging technique that could detect early stages of disease tissues. The combination of photoacoustic imaging with nanotechnology holds promise for determining the structural and functional properties of tissues with enhanced sensitivity and specificity and for monitoring the treatment of ...

Multiparameter Photoacoustic Tomography

2012
Physiology is the study of mechanical, physical, and chemical functions or organelles, cells, tissues, and organs in living systems. Disorders in physiological functions can lead to disease and death. Thus, studying physiology and pathophysiology in a quantitative manner is important for both fundamental and translational biomedicine.

Quantitative Photoacoustic Tomography

2011
This chapter focuses on quantitative photoacoustic tomography to recover optical maps from the deposited optical energy. After a brief overview of models, theories and algorithms, we provide an algorithm for large-scale 3D reconstructions, so-called gradient-based bound-constrained split Bregman method (GBSB).

Translational Photoacoustic Tomography

2016
Combining optical excitation and ultrasonic detection, photoacoustic tomography (PAT) offers deep imaging with high resolution. With optical excitation, PAT maintains the high contrast of optical imaging. Because of the low scattering of ultrasonic waves in tissue, PAT achieves high spatial resolution at depths. Several advantages make PAT suitable for
