The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. Within the NIR window, scattering is the most dominant light-tissue interaction, and … See more The absorption coefficient ($${\displaystyle \mu _{a}}$$) is defined as the probability of photon absorption in tissue per unit path length. Different tissue components have different $${\displaystyle \mu _{a}}$$ values. Moreover, See more Optical scattering occurs due to mismatches in refractive index of the different tissue components, ranging from cell membranes to … See more • Optical window • Near-infrared spectroscopy See more The NIR window can be computed based on the absorption coefficient spectrum or the effective attenuation coefficient spectrum. A possible criterion for selecting the NIR window is given by the FWHM of the inverse of these spectra as shown in Figure 7. See more WebSep 1, 2024 · Excited by 980 nm laser, saturated emissions from Tm 3+: 3 H 4 → 3 H 6 (~800 nm: first biological window NIR-I) and Tm 3+: 3 F 4 → 3 H 6 (~1800 nm: third biological window NIR-III) transitions are readily obtained owing to the efficient upconversion processes in the core/multishells nanoparticles, finally resulting in the …

Web使用Reverso Context: Magnetic resonance stimulation delivered by the iMRS within the biological window can have a profoundly positive impact on health. Stimulation at frequencies and amplitudes outside the biological window will produce little or no positive health benefit.，在英语-中文情境中翻译"biological window" WebJul 2, 2024 · Cancer phototheranostics in second biological window (1000–1500 nm) has recently emerged as a promising alternative of first biological window because of high light penetration depth, minimal tissue absorption, reduced scattering, better resolution, less autofluorescence, and high signal to noise ratio. With the rapid progress in chemical ... sharon r jenkins syracuse
