diffusion (s) (noun), diffusions (pl)
The scattering of light in many directions as the result of reflection from an uneven surface or passage though a translucent material: Jane wanted to have a thin curtain in front of her window to produce diffusion in the living room so she could read without the glaring sunlight from outside blinding her.

atmospheric diffusion (s) (noun), atmospheric diffusions (pl)

diffusion tensor imaging (DTI)
1. Measuring the movement of water in the brain, detecting areas where the normal flow of water is disrupted.

A disrupted flow of water indicates where there could be an underlying abnormality in the brain.

2. A new type of magnetic resonance technology which has, among other things, for the first time shown "white matter" in action, revealing its role in the brain.

Although gray matter (composed of neurons) does the brain's thinking and calculating, white matter (composed of myelin-coated axons, or long fibers of nerve cells), control the signals which neurons share, co-ordinating how well brain regions work together.

Diffusion tensor imaging (DTI) is done with the same kind of magnetic resonance imaging (MRI) machines found in hospitals; however, it involves a different type of magnetic field and different algorithms to create the many brain-image slices that are assembled into a three-dimensional picture.

diffusion weighted imaging (DWI)
Magnetic resonance technology presenting images of the body in which areas of rapid proton diffusion can be distinguished from areas with slow diffusion.

DWI, or diffusion weighted imaging, has been demonstrated to be more sensitive for the early detection of stroke than standard pulse sequences and is closely related to temperature mapping.
