Vector

Question 1

Vector Images (Segmentation)

Answer 1

• direct or indirect measurements of motion

- segmentation based on: strength of motion, direction of motion, connectivity

Question 2

Streamlines / Pathlines

Answer 2

• streamline: a line that is tengential to instantaneous velocity vector (one timepoint)
• pathline: trajectory of single particle release from a fixed location (path through time resolved vector field)

Question 3

Connectivity

Answer 3

• amount of particles which reach target voxel until time point t
• i.e. from which point in aorta can plaque travel to the brain?

Question 4

Vector pattern Analysis

Answer 4

• detect and quantify characteristic flow patterns

- vortex, swirl, orientation,…
