The "neglect b<" threshold allows you to ignore b-values smaller then a threshold for the initial fit of f and D. D* is then estimated using all measurements. The exact values of the current fit are always given in the legend underneath the figure. -\section QmitkDiffusionImagingUserManualInputData Region of interest analysis +\section QmitkIVIMViewROIAnalysis Region of interest analysis Create region of interest: To create a new segmentatin, open the "quantification" perspective, select the tab "Segmentation", and create a segmentation of the structure of interest. Alternatively, of course, you may also load a binary image from file or generate your segmentation in any other possible way. IVIM in region of interset: Go back to the "IVIM" perspective and select both, the diffusion image and the segmentation (holding the CTRL key). A red message should appear "Averaging N voxels". -\section QmitkDiffusionImagingUserManualInputData Export +\section QmitkIVIMViewExport Export All model parameters and corresponding curves can be exported to clipboard using the buttons underneath the figure. -\section QmitkDiffusionImagingUserManualInputData Advanced Settings +\section QmitkIVIMViewAdvanced Advanced Settings Advanced users, that know what they are doing, can change the method for the model-fit under "Advanced Settings" on the very bottom of the view. 3-param fit, linear fit of f/D, and fix D* are among the options. -\section QmitkDiffusionImagingUserManualInputData Suggested Readings +\section QmitkIVIMViewReferences Suggested Readings Toward an optimal distribution of b values for intravoxel incoherent motion imaging.
