Optical properties of human aorta: Are they affected by cryopreservation?

This study was undertaken to investigate the effects of freezing upon the in vitro optical properties of human aorta from 300 nm to 800 nm. Freezing significantly decreased absorption coefficient over most of the spectrum from 300 nm to 800 nm. The only significant changes in the reduced scattering coefficient were from 300 nm to 335 nm. © 1994 wiley‐Liss, Inc.
