Scientific Volume Imaging b.v.
The Twin Slicer is a Volume Visualization tool for 3D microscopy data, which is available in Huygens Essential and Huygens Professional. It works also in FreeWare mode, without a License String.
The Twin Slicer allows you to synchronize views of two images, measure distances, plot line profiles, etc. In Basic Mode (also available without a license), image comparison is intuitive and easy, while the Advanced Mode gives the user the freedom to rotate the cutting plane to any arbitrary orientation, link (synchronize) or unlink viewing parameters between the two images, and more.
To launch the Huygens Twin Slicer, select an image and choose 'Twin Slicer' from the 'Visualization' menu in the main menu. To view another image in an existing slicer, click the image name in the drop-down menu above the displayed slice.
Click and hold the right mouse button on the slice to move it around. Clicking the Center (
) button or pressing 'c' centers the slice.
Drag the slider beneath the displayed slice to move the cutting plane back and forth. This can also be achieved using the buttons adjacent to the slider (
and 
), the up/down arrow keys on the keyboard, or by placing the mouse pointer over the slider and using the scroll wheel. The play button moves the cutting plane through the data volume. The pointer coordinates can be displayed through the 'View' menu.
Note that it is possible to move the cutting plane out of the volume. Pressing the Center button () or the 'c' key centers the plane again.
Drag the slider in the 'Time frame' panel to change the time frame or press the play button to animate the time series. The time frame can be displayed through the 'View' menu.
Make a selection in the 'Orientation' panel to change the plane used to display the image.
Click the buttons in the 'Zoom' panel or use the scroll wheel to zoom in or out on the location of the mouse pointer.
Click an option in the 'Colors' panel to select a color scheme:
You can adjust the brightness in the 'Brightness' panel using the buttons (
and 
), dragging the slider, or putting the mouse pointer over the slider and using the scroll wheel.
The 'Gamma' drop panel provides you with a linear and some non-linear ways of mapping data values to pixel intensities.
