On the link between the speckle free nature of optoacoustics and visibility of structures in limited-view tomography

Photoacoustics, 2016
Similar to pulse-echo ultrasound, optoacoustic imaging encodes the location of optical absorbers by the time-of-flight of ultrasound waves. Yet, signal generation mechanisms are fundamentally different for the two modalities, leading to significant ...

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, Volume 5, Issue 4, October 2026.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Optimization of light source parameters for photoacoustic imaging: trade-offs, technologies, and clinical considerations

JPhys Photonics
The selection of light sources for photoacoustic imaging, a biomedical imaging technology, remains a critical yet under-informed topic. This review discusses the key trade-offs in light source parameters (e.g.

Epileptogenic lesions in the Australian epilepsy project: A harmonized 3‐T magnetic resonance imaging protocol and its diagnostic yield

Epilepsia, Volume 67, Issue 10, Page 5398-5411, October 2026.
Abstract Objective Detection of epilepsy‐causing structural brain lesions on magnetic resonance imaging (MRI) is critical for diagnosis, prognosis, and treatment planning in people with epilepsy. We aimed to establish an epilepsy‐directed multisite harmonized 3‐T MRI acquisition protocol for the Australian Epilepsy Project (AEP) and describe the ...

Imaging of blood flow and oxygen state with a multi-segment optoacoustic ultrasound array

Photoacoustics, 2018
Changes in hemodynamic parameters are directly linked to biological function and physiological activity. Characterization of hemodynamics is commonly performed by Doppler ultrasound, which provides accurate measurements of blood flow velocity.

MicroRNA–mRNA Networks in Skeletal Muscle of Tailored Pig Models for Dystrophinopathies

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are X‐linked dystrophinopathies caused by mutations in the dystrophin (DMD) gene. A common DMD‐causing mutation in humans is exon 52 deletion (DMDΔ52), which disrupts the reading frame and abolishes dystrophin expression.

Surface‐Enhanced Raman Scattering‐Based Multimodal Medical Imaging in Cancer Diagnosis and Therapy Monitoring

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

Non‐invasive Imaging Modalities for Breslow Thickness Estimation in Melanoma: A Scoping Review

Skin Research and Technology, Volume 32, Issue 10, October 2026.
ABSTRACT Background Breslow thickness (BT) is the most important prognostic biomarker in cutaneous melanoma and directly influences surgical management, sentinel lymph node biopsy decisions and survival outcomes. Several non‐invasive imaging modalities have been investigated for preoperative BT estimation; however, their relative performance and ...
