Regional LV function
There are extended possibilities to plot various regional parameters. There are three main visualization modes report per slice, segmental view, and bullseye plot.
Report per slice
It is possible to do regional wall motion analysis on a slice by slice basis. Possible parameters to plot are wall thickness, fractional wall thickening, radial contraction velocity, and radius.
Segmental view
It is possible to plot radial contraction velocity over time in six different sectors and each slice in a matrix style.
Note the apical to basal gradient in the onset of the radial contraction.
Bullseye plots
The parameters that currently can be plotted as bullseye plots are:
- Maximal expansion velocity
- Maximal contraction velocity
- Expansion velocity at peak filling rate
- Contraction velocity at peak ejection rate
- Maximal wall thickness
- ED wall thickness
- ES wall thickness
- Wallthickening (difference wall thickness ES-ED)
- Fractional wall thickness
- Myocardial volume
- Scar transmurality (not yet publically available)
- Max scar transmurality (not yet publically available)
The orientation of the bulls eye plot can be adjusted by a slider, and the number of sectors with a listbox. It is also possible to export the results of the bulls eye plot to clipboard (to later paste it into for instance Excel).
