Photoacoustic computed tomography guided microrobots for targeted navigation in intestines in vivo [PDF]

, 2020
Tremendous progress in synthetic micro/nanomotors has been made for potential biomedical applications. However, existing micro/nanomotor platforms are inefficient for deep tissue imaging and motion control in vivo.

High-resolution photoacoustic microscopy with deep penetration through learning

Photoacoustics, 2021
Optical-resolution photoacoustic microscopy (OR-PAM) enjoys superior spatial resolution and has received intense attention in recent years. The application, however, has been limited to shallow depths because of strong scattering of light in biological ...

SCANNING PHOTOACOUSTIC MICROSCOPY

Acta Physica Sinica, 1982
The principle, possible applications and prospects of the scanning photoacoustie microscopy are described briefly. The microscopy system presented herewith attains a resolution of about 4,5 μm. Some images of such samples as the interdigital transducer of surface acoustic wave, integrated circuit and in particular the subsurface structure of the ...

Photoacoustic imaging of squirrel monkey cortical and subcortical brain regions during peripheral electrical stimulation

Photoacoustics, 2022
The investigation of neuronal activity in non-human primate models is of critical importance due to their genetic similarity to human brains. In this study, we tested the feasibility of using photoacoustic imaging for the detection of cortical and ...

Simultaneous imaging of a lacZ-marked tumor and microvasculature morphology in vivo by dual-wavelength photoacoustic microscopy [PDF]

, 2008
Photoacoustic molecular imaging, combined with the reporter-gene technique, can provide a valuable tool for cancer research. The expression of the lacZ reporter gene can be imaged using photoacoustic imaging following the injection of X-gal, a ...

Accelerated High-Resolution Photoacoustic Tomography via Compressed Sensing [PDF]

, 2016
Current 3D photoacoustic tomography (PAT) systems offer either high image quality or high frame rates but are not able to deliver high spatial and temporal resolution simultaneously, which limits their ability to image dynamic processes in living tissue.

Unsupervised deep learning enables real-time image registration of fast-scanning optical-resolution photoacoustic microscopy

Photoacoustics
A fast scanner of optical-resolution photoacoustic microscopy is inherently vulnerable to perturbation, leading to severe image distortion and significant misalignment among multiple 2D or 3D images.
