ABSTRACT
Medical imaging allows us to see the diseased organ/tissue/cells as well as the
effect of the treatment. It has been playing a more and more important role
in modern medicine, demonstrating that diagnosis determines prognosis and,
furthermore, that even fatal disease may become curable or at least controllable
if diagnosed at the earliest stage. There have been a lot of well-established
technologies for practical and effective medical imaging, including optical
imaging (OI) based on visible fluorescence or near infrared fluorescence (NIRF),
magnetic resonance imaging (MRI), radionuclide imaging such as positron
emission tomography (PET) and single photon emission computed tomography
(SPECT), x-ray computed tomography (CT), and ultrasound imaging (US), which
have been widely applied and demonstrated superb performance in the clinic.
