Interacting with MicroView
This section describes the elements of how to interact with image display in MicroView.
| Function | Description |
|---|---|
| Window and Level | Adjust Window and Level values to control image contrast and brightness. Window and Level values can be modified by using the scrollbars at the bottom of the MicroView window, or by selecting the window/level button on the interaction palette, then click-and-dragging the left mouse button in any of MicroView's viewports. The behavior and values of the window/level scrollbars can be adjusted by clicking on the Window/Level value display, in the bottom right corner of MicroView's main window. Note Image contrast and brightness can also be controlled by selection of image minimum and maximum values. From MicroView's "Application Settings..." menu, select the "Misc" tab, then select Use Min/Max for W/L control. Once selected, Window and Level scrollbars will be replaced by Min and Max scrollbars. |
| Image Rotate (3D) | Move the mouse in the 3D viewport while clicking the left mouse button to rotate the image. By default, the image will rotate about its center, while the mouse is dragged. However, clicking and dragging the left mouse button in the bottom portion of the 3D viewport will cause the image to rotate about an axis parallel to the viewing direction. |
| Image Pan | Click and drag the left mouse button, while pressing one of the Shift keys to pan the image up, down, left or right. |
| Image Slice (3D) | Move the mouse over the center region of a slice plane. Drag the mouse, while pressing the middle mouse button to interactively slice through the image. Press the Up or Down Arrow key while the mouse is positioned over the center region of a slice plane in order to move the slice forwards or backwards in the image by one slice. Press the PgUp or PgDn key while the mouse is positioned over the center region of a slice plane in order to move the slice forwards or backwards in the image by ten slices. Press the Home and End keys to select the first and last image slice, respectively. |
| Image Slice Orientation (3D) | Position the mouse within the 3D viewport, on the edge, or corner of an image slice. Press the middle mouse button and drag the mouse up and down or left and right to rotate the orientation of the three slice planes within the image. When a corner is picked, the plane border color will change to red and the plane will rotate around the plane normal. When an edge is picked, the plane border color will change to cyan and the plane will rotate around the plane center line that parallels to the picked edge. |
| Image Zoom | Click and drag the right mousebutton up or down, to zoom in or out, respectively, on the image. |
| Maximize Viewport | Double-click the left mouse button while the mouse is positioned within any of MicroView's four viewports to view only the selected viewport. MicroView will expand the selected viewport to occupy the entire working space of the MicroView window. Double-click on the viewport again to restore the original screen layout. |
| Reset all Viewports | Press the r key to restore slice selection and view orientation to their original settings. |
| Center Slice Intersection | Click the left mouse button, while pressing the Ctrl key over the image, in any viewport. The intersection of the three image slices will move to the current location selected by the mouse position. |
