Eigenspectra optoacoustic tomography achieves quantitative blood oxygenation imaging deep in tissues

open access: yes, 2015
Light propagating in tissue attains a spectrum that varies with location due to wavelength-dependent fluence attenuation by tissue optical properties, an effect that causes spectral corruption.

Dumbbell‐Structured Plasmonic‐Enhanced Optical Nanoprobes Boosting Photo‐Magnetic‐Acoustic Multimodal Imaging‐Guided Photodynamic‐Photothermal Synergistic Treatment and Immunogenic Death in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
This study reports a novel rationally‐designed optical nanoprobe based on dumbbell‐shaped mesoporous silica‐coated gold nanorods, loaded with rare‐earth oxides, photosensitizers, and tumor‐targeted peptides, enabling plasmonic‐enhanced multimodal imaging and PTT‐PDT synergy.

Soft ultrasound priors in optoacoustic reconstruction: Improving clinical vascular imaging

open access: yesPhotoacoustics, 2020
Using the same ultrasound detector, hybrid optoacoustic-ultrasound (OPUS) imaging provides concurrent scans of tissue slices or volumes and visualizes complementary sound- and light-based contrast at similar resolutions.

The Dual-Targeted Peptide Conjugated Probe for Depicting Residual Nasopharyngeal Carcinoma and Guiding Surgery

open access: yesBiosensors, 2022
Detecting residual nasopharyngeal carcinoma (rNPC) can be difficult because of the coexistence of occult tumours and post-chemoradiation changes, which poses a challenge for both radiologists and surgeons using current imaging methods.

A Novel Real-Time Non-invasive Hemoglobin Level Detection Using Video Images from Smartphone Camera [PDF]

open access: yes, 2017
Hemoglobin level detection is necessary for evaluating health condition in the human. In the laboratory setting, it is detected by shining light through a small volume of blood and using a colorimetric electronic particle counting algorithm.

Graphics processing unit accelerating compressed sensing photoacoustic computed tomography with total variation [PDF]

open access: yes, 2020
Photoacoustic computed tomography with compressed sensing (CS-PACT) is a commonly used imaging strategy for sparse-sampling PACT. However, it is very time-consuming because of the iterative process involved in the image reconstruction.

Seeing the Speaker's Face Enhances Second Language Shadowing: Neural and Behavioral Evidence

open access: yesLanguage Learning, EarlyView.
Abstract This functional magnetic resonance imaging (fMRI) study investigated how facial cues influence second language (L2) shadowing among 42 Japanese learners of English. Participants completed four conditions that varied by task type (listening vs. shadowing) and visual input (face vs. mosaic).

Fluence compensation in raster-scan optoacoustic angiography

open access: yesPhotoacoustics, 2017
Modern optical imaging techniques demonstrate significant potential for high resolution in vivo angiography. Optoacoustic angiography benefits from higher imaging depth as compared to pure optical modalities.
