4-D Photoacoustic Tomography
Photoacoustic tomography (PAT) offers three-dimensional (3D) structural and functional imaging of living biological tissue with label-free, optical absorption contrast. These attributes lend PAT imaging to a wide variety of applications in clinical medicine and preclinical research. Despite advances in live animal imaging with PAT, there is still a need for 3D imaging at centimeter depths in re...
متن کاملNeurovascular Photoacoustic Tomography
Neurovascular coupling refers to the relationship between neuronal activities and downstream hemodynamic responses. Photoacoustic tomography (PAT), enabling comprehensive label-free imaging of hemodynamic activities with highly scalable penetration and spatial resolution, has great potential in the study of neurovascular coupling. In this review, we first introduce the technical basis of hemody...
متن کاملQuantitative Fluorescence Photoacoustic Tomography
Fluorescence photoacoustic tomography (fPAT) is a multi-modality biomedical imaging technique that combines the high-resolution ultrasound imaging with the highcontrast 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. In the second step, called quantitative fPAT...
متن کاملQuantitative Photoacoustic Tomography
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).
متن کاملProspects of photoacoustic tomography.
Commercially available high-resolution three-dimensional optical imaging modalities-including confocal microscopy, two-photon microscopy, and optical coherence tomography-have fundamentally impacted biomedicine. Unfortunately, such tools cannot penetrate biological tissue deeper than the optical transport mean free path (approximately 1 mm in the skin). Photoacoustic tomography, which combines ...
