Advanced Paint and Power Paint tools
Advanced paint
Power Paint tool
The Power Paint tool has three options
The Power Paint tool works either on the original image or its triplanar viewer.
To run the Advanced Paint tool,
Multiple Paint Tools dialog box options
Paint mask palette
|
Advanced Paint uses a color palette that contains a limited number of colors and each color is described explicitly in the palette. The palette colors themselves are the same as MIPAV uses for stripped LUT. By default, a value from 1 to 24 assigned to each palette button identifies which of the colors in the palette to use. When you click any Paint Mask Palette button, e.g. the button 1, both - the button and the paint brush - appear highlighted with the color assigned to that button. This might remind you of painting by numbers.

To run the Power Paint tool,
Paint Power Tools dialog box options
Object processing
| |||
The object processing can be done for 2D and 3D images. To specify the type of the image, use the corresponding radio button. Grow Region option can be used to grow paint inside a region of interest (e.g., VOI) of a mask. This tool works similar to the usual region growing tool, but it uses only one intensity value and the specified connectivity.
| |||
Fill Background - allows to fill the background. Fill All Background -TBD. Remove object - removes a selected object. Remove All Objects - removes a selected object. Connectivity - TBD. Threshold specifies the upper and lover threshold for the image intensities to paint on. By default, you can paint everywhere, but if you move the sliders further in, you can see that any new paint you add will not affect the lowest or highest image intensities.
