|Initial release||22 April 2009|
|Latest version||v1.2 (23 April 2009)|
This plugin is simply a dynamic version of the Reslice command as it is in ImageJ version 1.42l, by Patrick Kelly, Harvey Karten, Wayne Rasband, Julian Cooper and Adrian Deerr. It draws an orthogonal slice through the volume represented by the stack it is applied on along its ROI, and update dynamically this slice as the ROI is displaced or deformed.
Download the jar file Dynamic_Reslice.jar and drop it into the plugins menu. The plugin will appear in the menu. ▶
The plugin is part of the Fiji distribution, as a member of the Fiji_Plugins package. You can find it in the menu. ▶
Open a stack and draw a line roi on it (any line roi will do it: straight line, poly-line, freehand line). When you call the plugin you are asked for two parameters.
- Flip vertically will cause the source slices to be processed from bottom to top.
- Rotate 90º will cause the result display to be rotated by 90º.
The reslice window is drawn. Now change the roi shape or move it with the mouse. The result window refreshes automatically. Is is possible to change roi type on the fly.
It is possible to call and control this plugin from other plugin or scripts. Here is a script example for use with Fiji.
''' This jython script intends at demonstrating how to script the Dynamic_Reslice plugin. It will open the t1-head sample stack in Fiji, draw a ROI on it, and animate it while updating the Reslice image.
