摘要:
Disclosed are methods and devices useful for imaging blood-containing tissue, for example for angiography, especially retinal angiography, whereby an image is generated by dividing pixels of an image acquired at some wavelength range by corresponding pixels of an image acquired at a different wavelength range. In some embodiments, a first wavelength range includes predominantly light having wavelengths between about 400 nm and about 620 nm and a second wavelength range includes predominantly light having wavelengths between about 620 nm and about 800 nm.
摘要:
Disclosed are methods and devices comprising an elongated probe for the in vivo detection of meconium in amniotic fluid held in an amniotic sac based on detecting the presence of Zinc-coproporphyrin I (ZnCP). ZnCP is excited at approximately 405 nm and emits characteristic fluorescence, centered at about 580 nm and less intensely at 630 nm.
