Melanoma accounts for 75% of all skin cancer deaths. Pulsed photothermal radiometry (PPTR), optical coherence tomography (OCT) and ultrasound (US) are non-invasive imaging techniques that may be used… Expand
Femtosecond laser lithotripsy: feasibility and ablation mechanism.
Light emitted from a femtosecond laser is capable of plasma-induced ablation of various materials. We tested the feasibility of utilizing femtosecond-pulsed laser radiation (lambda=800 nm, 140 fs,… Expand

- 1 November 2014
BACKGROUND AND OBJECTIVES Non-ablative fractional lasers cause little down-time, however, some patients want more noticeable results with fewer treatments. The 1940 nm wavelength matches one of the… Expand
Dual-wavelength multifrequency photothermal wave imaging combined with optical coherence tomography for macrophage and lipid detection in atherosclerotic plaques using gold nanoparticles.
The objective of this study was to assess the ability of combined photothermal wave (PTW) imaging and optical coherence tomography (OCT) to detect, and further characterize the distribution of… Expand
Deep subsurface cavities in skin utilizing mechanical optical clearing and femtosecond laser ablation.
BACKGROUND AND OBJECTIVES High precision subsurface ablation can be produced in transparent materials using femtosecond laser pulses and multiphoton absorption. Light scattering limits application of… Expand
