In vivo optical assessment of cerebral and skeletal muscle microvascular response to phenylephrine Open

Laura Mawdsley, Rasa Eskandari, Farah Kamar, Ajay Rajaram, Lawrence C. M. Yip , et al. · 2024

This study aimed to investigate the simultaneous response of the cerebral and skeletal muscle microvasculature to the same phenylephrine (PE) boluses. A hybrid optical system that combines hyperspectral near‐infrared spectroscopy (hs‐NIRS)…

Photoacoustic tomography as a method to estimate the optical fluence distribution in turbid media Open

Lawrence C. M. Yip, Elina Rašcevska, Parsa Omidi, Jeffrey J. L. Carson · 2023

Currently, there are no non-invasive experimental methods available for measuring optical fluence distributions in tissue. We present photoacoustic tomography (PAT) as a method to approximate the relative optical fluence distribution in a …

Single-shot 4-step phase-shifting multispectral fringe projection profilometry Open

Parsa Omidi, Mohamadreza Najiminaini, Mamadou Diop, Jeffrey J. L. Carson · 2021

Phase-shifting profilometry (PSP) is considered to be the most accurate technique for phase retrieval with fringe projection profilometry (FPP) systems. However, PSP requires that multiple phase-shifted fringe patterns be acquired, usually…

Multispectral intravital microscopy for simultaneous bright-field and fluorescence imaging of the microvasculature Open

G. Janssen, Mohamadreza Najiminaini, Yan Min Zhang, Parsa Omidi, Jeffrey J. L. Carson · 2021

Single-shot detection of 8 unique monochrome fringe patterns representing 4 distinct directions via multispectral fringe projection profilometry Open

Parsa Omidi, Mohamadreza Najiminaini, Mamadou Diop, Jeffrey J. L. Carson · 2021

PhaseWare: Phase map retrieval for fringe projection profilometry and off-axis digital holographic interferometry Open

Parsa Omidi, Lawrence C. M. Yip, Hui Wang, Mamadou Diop, Jeffrey J. L. Carson · 2021

Fringe projection profilometry and off-axis digital holographic interferometry are two techniques commonly used for non-contact optical surface measurement and movement tracking; however, they can be difficult to implement due to the compl…

Structured-light surface scanning system to evaluate breast morphology in standing and supine positions Open

Olivia Tong, Astrid Chamson-Reig, Lawrence C. M. Yip, Muriel Brackstone, Mamadou Diop , et al. · 2020

Breast shapes are affected by gravitational loads and deformities. Measurements obtained in the standing position may not correlate well with measurements in the supine position, which is more representative of patient position during brea…

Perfusion and Metabolic Neuromonitoring during Ventricular Taps in Infants with Post-Hemorrhagic Ventricular Dilatation Open

Ajay Rajaram, Lawrence C. M. Yip, Daniel Milej, Marianne Suwalski, Matthew Kewin , et al. · 2020

Post-hemorrhagic ventricular dilatation (PHVD) is characterized by a build-up of cerebral spinal fluid (CSF) in the ventricles, which increases intracranial pressure and compresses brain tissue. Clinical interventions (i.e., ventricular ta…

Lipid-weighted intraoperative photoacoustic tomography of breast tumors: Volumetric comparison to preoperative MRI Open

Ivan Kosik, Muriel Brackstone, Anat Kornecki, Astrid Chamson-Reig, Philip Wong , et al. · 2020

Development of a Human Photoacoustic Imaging Reporter Gene Using the Clinical Dye Indocyanine Green Open

Nivin N. Nyström, Lawrence C. M. Yip, Jeffrey J. L. Carson, Timothy J. Scholl, John A. Ronald · 2019

PURPOSE: To develop a photoacoustic imaging (PAI) reporter gene that has high translational potential. Previous research has shown that human organic anion–transporting polypeptide 1b3 (OATP1B3) promotes the uptake of the near-infrared flu…

Intraoperative photoacoustic screening of breast cancer: a new perspective on malignancy visualization and surgical guidance Open

Ivan Kosik, Muriel Brackstone, Anat Kornecki, Astrid Chamson-Reig, Philip Wong , et al. · 2019

High re-excision rates in breast-conserving surgery call for a new intraoperative approach to the lumpectomy margin evaluation problem. The unique intraoperative imaging system, presented here, demonstrated the capability of photoacoustic …

A human photoacoustic imaging reporter gene using the clinical dye indocyanine green Open

Nivin N. Nyström, Lawrence C. M. Yip, Jeffrey J. L. Carson, Timothy J. Scholl, John A. Ronald · 2019

Photoacoustic imaging (PAI) combines optical contrast with the resolution and depth-detection of ultrasound and is increasingly being utilized for medical imaging in patients. PAI reporter genes would allow for monitoring of cell and gene …

Objective Assessment and Design Improvement of a Staring, Sparse Transducer Array by the Spatial Crosstalk Matrix for 3D Photoacoustic Tomography Open

Philip Wong, Ivan Kosik, Avery Raess, Jeffrey J. L. Carson · 2015

Accurate reconstruction of 3D photoacoustic (PA) images requires detection of photoacoustic signals from many angles. Several groups have adopted staring ultrasound arrays, but assessment of array performance has been limited. We previousl…
