Aarts, LAM; Jeanne, V; Cleary, JP; Lieber, C; Nelson, JS; Bambang Oetomo, S; et al.(2013). Non-contact heart rate monitoring utilizing camera photoplethysmography in the neonatal intensive care unit-A pilot study. Early Human Development, 89(12), 943-948. doi: 10.1016/j.earlhumdev.2013.09.016. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/66w2q2sj

Background: Presently the heart rate is monitored in the Neonatal Intensive Care Unit with contact sensors: electrocardiogram or pulse oximetry. These techniques can cause injuries and infections, particularly in very premature infants with fragile s

Autor: Verkruysse, W, Svaasand, LO, Franco, W, Nelson, JS

Publikováno v: Verkruysse, W; Svaasand, LO; Franco, W; & Nelson, JS. (2009). Remittance at a single wavelength of 390 nm to quantify epidermal melanin concentration. Journal of Biomedical Optics, 14(1). doi: 10.1117/1.3065542. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/6rc554tp

Objective quantification of epidermal melanin concentration (EMC) should be useful in laser dermatology to determine the individual maximum safe radiant exposure (IMSRE). We propose a single-wavelength remittance measurement at 390 nm as an alternati
