Reducing tissue inflammation
Detecting early-stage cancers
Measuring blood pressure
FLIM can be combined with Raman spectroscopy to provide information about both ___________.
Molecular composition and fluorescence decay
Elasticity and scattering
Reflectivity and temperature
Absorption and emission spectra
Raman spectroscopy detects molecular vibrations based on the ___________ shift of scattered light.
Fluorescence
Wave length
Frequency
Time
Speckles are created due to ___________ of light waves scattered by tissue microstructures.
Reflection

Interference
A patient with suspected liver fibrosis undergoes elastography. Which physical property of the liver tissue will the physician analyze to confirm stiffness.
Elasticity
Temperature
Fluorescene
Colour
The principle behind Laser-Induced Fluorescence (LIF) is based on the emission of light when:
Molecules reflect the incident light
Tissues absorb all the incident light
Molecules absorb laser energy and re-emit it at longer wavelengths
Electrons get displaced from their orbitals
A clinician wants to non-invasively detect early signs of cancer by analyzing molecular vibrations in tissue. Which optical technique should be applied for this purpose?
Optical coherence tomography
Raman spectroscopy
Fluorescence
Speckle imaging
