Epileptogenic lesions in the Australian epilepsy project: A harmonized 3-T magnetic resonance imaging protocol and its diagnostic yield. [PDF]
EpilepsiaAbstract 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 ...

Combined two frequency array for optoacoustics and acoustics
, 2022 S.3783A combined transducer for optoacoustics and b-mode ultrasound has to be built according to the specific requirements of both modalities. In order to combine the two tasks in one transducer, we have designed a probe consisting of a PZT array and a ...

Clinical and Translational Imaging and Sensing of Diabetic Microangiopathy: A Narrative Review
Journal of Cardiovascular Development and Disease, 2023 Microvascular changes in diabetes affect the function of several critical organs, such as the kidneys, heart, brain, eye, and skin, among others. The possibility of detecting such changes early enough in order to take appropriate actions renders the ...

A multichannel system for real-time optoacoustics and its suitability for molecular imaging
, 2022 S.537-540In optoacoustics, the good resolution of ultrasound is combined with the excellent contrast of optical methods. We developed a system capable of acquiring signals of up to 128 channels simultaneously for real-time optoacoustic imaging.

Photoacoustic detection of circulating melanoma cells in late stage patients
Journal of Innovative Optical Health Sciences, 2020 Melanoma is the deadliest skin cancer and is responsible for over 7000 deaths in the US annually. The spread of cancer, or metastasis, is responsible for these deaths, as secondary tumors interrupt normal organ function. Circulating tumor cells, or those

Photocontrollable Proteins for Optoacoustic Imaging [PDF]
Analytical Chemistry, 2019 Photocontrollable proteins revolutionized life-science imaging due to their contribution to subdiffraction-resolution optical microscopy. They might have yet another lasting impact on photo- or optoacoustic imaging (OA). OA combines optical contrast with ultrasound detection enabling high-resolution real-time in vivo imaging well-beyond the typical ...
