4. 'Draw parameters' panel

'Draw parameters' panel

Set the minimum and maximum value of Contrast data and Structure image with the slider of 'Draw parameters' panel and the numerical value box. 'Slice image' figure appears as the left of the figure below by clicking the 'Draw slice image' button. In 'Slice image' figure, the Contrast data is piled up with the range of minimum value (Contrast MIN) and maximam value (Contrast MAX) which are specified on the 'Draw parameters' panel with the slice image of the Stracture image. (*1) The Contrast data with less than minimum value (Contrast MIN) of voxel is not plotted on the Contrast Map, but the value of more than maximum(Contrast MAX) is plotted on the Contrast Map. By clicking on the 'Reset draw parameters' button, the minimum and maximum value of Contrast data to show the Stracture image is initialized (*2).  Moreover, by clicking on 'Draw colormap' button, 'Colormap' figure appears and Colormap bar used for 'Slice image' figure is displayed.

(*2)
In the initial state, minimum value(Contrast MIN) and maximum value(Contrast MAX) of Contrast data refers minimum and maximum values of each Contrast data file. On the other hand, minimum value(Structure MIN) and maximum value(Structure MAX) of the Structure image refers the value calculated by the following formula with minimum and maximum values of each Contrast data file.

Structure MIN = 0.1*(struct_max - struct_min) + struct_min;
Structure MAX = 0.9*(struct_max - struct_min) + struct_min;
