This page displays the 3D MR image volume and PK modeling color maps.
Rotate the image about its three axes by clicking and dragging on the
volume. Zoom in or out using your mouse scrollwheel or with touchpad
pinching gestures.
The buttons above the image at left let you display a map of PK modeling
results over the 3D volume. Color maps are turned off when the image is
initially loaded. The following overlay options may be included:
* ΔK<sub>trans</sub>: the measure of the shutter speed effect on
K<sub>trans</sub> estimation (i.e., FXL K<sub>trans</sub> subtracted
from FXR K<sub>trans</sub>)
* FXL K<sub>trans</sub>: the vascular permeability transfer constant for
the standard model
* FXR K<sub>trans</sub>: the vascular permeability transfer constant for
the shutter speed model
* τ<sub>i</sub>: the FXR intracellular H<sub>2</sub>O mean lifetime
* v<sub>e</sub>: the FXR extravascular extracellular volume fraction
Click on the <span class="glyphicon glyphicon-info-sign"></span> button
to the left of the overlay buttons to view details about modeling input
and registration (motion correction).
On the right, the image control panel lets you adjust the appearance of
the 3D image and overlay. The following controls are available:
* Opacity: Drag the slider to adjust the transparency of the volume.
* Cross Section: Drag these sliders to control the cross sectional
slicing of the image along the sagittal, coronal, and axial planes.
* Threshold: Drag these sliders to adjust the lower and upper bounds of
the threshold range. This operation converts each voxel in the image
into black, white, or unchanged depending on whether the original
color value is within the range.
