ere has been tremendous progress in medicine and biol-
ogy over the past few decades. During this time, we have wit-
nessed previously unimaginable advances in the understanding
of human biology and physiology. One notable example is the
human genome project, which has opened up new insights into
disease diagnosis and therapy. Science and engineering have
been instrumental in harnessing this new knowledge into clini-
cally practical solutions. Within the eld of medical imaging,
the use of light plays an increasingly important role to reveal
functional, structural, and molecular information nondestruc-
tively; also, interes
