Journal ArticleDOI
Remote plethysmographic imaging using ambient light
TL;DR: Plethysmographic signals were measured remotely (>1m) using ambient light and a simple consumer level digital camera in movie mode as discussed by the authors, which may be useful for medical purposes such as characterization of vascular skin lesions and remote sensing of vital signs (e.g., heart and respiration rates) for triage or sports purposes.
Journal ArticleDOI
Boundary conditions for the diffusion equation in radiative transfer
Richard C. Haskell,Lars O. Svaasand,Tsong-Tseh Tsay,Ti-Chen Feng,Matthew S. McAdams,Bruce J. Tromberg +5 more
TL;DR: It is concluded that noninvasive measurements of optically thick tissue require a rigorous treatment of the tissue boundary, and a unified partial-current--extrapolated boundary approach is suggested.
Journal ArticleDOI
Non-Invasive In Vivo Characterization of Breast Tumors Using Photon Migration Spectroscopy
Bruce J. Tromberg,Natasha Shah,Ryan M. Lanning,Albert E. Cerussi,Jennifer Espinoza,Tuan Pham,Lars O. Svaasand,John Butler +7 more
TL;DR: Clinical studies to quantitatively determine normal and malignant breast tissue optical and physiological properties in human subjects show that ductal carcinomas and benign fibroadenomas exhibit 1.25 to 3-fold higher absorption than normal breast tissue.
Journal ArticleDOI
Thermal and optical properties of living tissue: Application to laser-induced hyperthermia
TL;DR: This report discusses the thermal distribution in living tissue during hyperthermic treatment with visible or infrared electromagnetic irradiation with results from the treatment of a murine tumor model, C3H/Tif mammary adenocarcinoma in C3D2F1/Bom mouse strain.
Journal ArticleDOI
Dynamic Epidermal Cooling During Pulsed Laser Treatment of Port-Wine Stain: A New Methodology With Preliminary Clinical Evaluation
J. Stuart Nelson,Thomas E. Milner,Bahman Anvari,B. Samuel Tanenbaum,Sol Kimel,Lars O. Svaasand,Steven L. Jacques +6 more
TL;DR: In this article, the authors demonstrate the feasibility of selectively cooling the normal overlying epidermis without affecting the temperature of the deeper PWS vessels, while leaving the deeper vessels unchanged.
