Journal ArticleDOI
Correcting for motion artifact in handheld laser speckle images.
Ben Lertsakdadet,Bruce Y. Yang,Cody E. Dunn,Adrien Ponticorvo,Christian Crouzet,Nicole Bernal,Anthony J. Durkin,Bernard Choi +7 more
TL;DR: The results suggest the potential of handheld LSI with an FM as a suitable alternative to mounted LSI, especially in challenging clinical settings with space limitations such as the intensive care unit.
Journal ArticleDOI
Comparison of speckleplethysmographic (SPG) and photoplethysmographic (PPG) imaging by Monte Carlo simulations and in vivo measurements.
TL;DR: An eight-layer tissue model is developed to simulate both PPG and SPG signals in a reflectance geometry via Monte Carlo methods and suggests SPG has a much larger SNR than PPG, which may prove beneficial for noncontact, wide-field optical monitoring of cardiovascular health.
Journal ArticleDOI
Preclinical In Vivo Evaluation of Npe6-Mediated Photodynamic Therapy on Normal Vasculature
Wesley J. Moy,Shreyas J. Patel,Ben Lertsakdadet,Rajan P. Arora,Katherine M. Nielsen,Kristen M. Kelly,Bernard Choi +6 more
TL;DR: Evaluated a PDT protocol that involves use of an alternate intravascular photosensitizer mono‐L‐aspartylchlorin‐e6 (NPe6) activated by an array of low‐cost light emitting diodes to photocoagulate both small and large vasculature.
Journal ArticleDOI
Handheld Motion Stabilized Laser Speckle Imaging
TL;DR: A handheld gimbal stabilizer (HGS) is incorporated to produce a motion stabilized LSI (msLSI) device to further improve the quality of data acquired in handheld configurations and display the improved usability of handheld data acquired with an msLSI device.
Journal ArticleDOI
Intravital Vascular Phototheranostics and Real-Time Circulation Dynamics of Micro- and Nanosized Erythrocyte-Derived Carriers
Wangcun Jia,Joshua M. Burns,Betty Villantay,Jack C. Tang,Raviraj Vankayala,Ben Lertsakdadet,Bernard Choi,J. Stuart Nelson,Bahman Anvari +8 more
TL;DR: This work investigated the circulation dynamics of micro and nano-sized erythrocyte-derived carriers in real time using near-infrared fluorescence imaging, and evaluated the effectiveness of such carrier systems in mediating photothermolysis of cutaneous vasculature in mice.
