BrainStat GVF workflow

Use these steps to generate parametric images from a time course data set. The generated maps are based on a Gamma Variate Fit.

1. Open READY View and launch the BrainStat GVF protocol.
   • When BrainStat GVF launches, the source, image maps and time/intensity curve display. The image/graph displayed in each viewport is based on the selected protocol.
2. Scroll through the images to locate images that best demonstrate the automatic vessel detection.
   • For details, see Scroll through the images.
3. Adjust W/L and mag factor. Place the cursor in the desired viewport.
   • Middle-click and drag to adjust the W/L. Note that BrainStat initially applies best-estimate window width and level values for the Blood Flow and Blood Volume maps.
   • For details, see:
     • Change the image magnification or minification
     • Adjust the image Window Width and Level
