Getting Started with DTI-TK Quick Look Plugin    
Copyright © 2009 Gary Hui Zhang

Overview


This plugin uses the Mac OS X Leopard's built-in innovative Quick Look framework to enable a quick assessment of any 3-dimensional image volume in the supported medical image formats directly from the Finder. Using the Finder's Cover Flow mode, a large collection of medical images can be browsed through and quickly inspected just as easy as flipping through your photos. Furthermore, a large number of images can be compared side-by-side by selecting them together in the Finder, then pressing the space bar to bring up the Quick Look preview mode.

Current Version

The current version is 1.8.3, released on June 2nd, 2010, with minor enhancement. The complete change log is available here.

Download & Installation

The current release can be downloaded from here for snow leopard and here for leopard.

To install the plugin, simply copy (drag-and-drop from Finder) the "DTITK_QuickLookPlugin.qlgenerator"  either to the directory /Library/QuickLook (if you want to make it available system wide) or to the directory ~/Library/QuickLook (if you want to make it available locally).  Create the directory if it does not already exist.

Sometimes, the older version of the plugin may be cached in the memory.  To purge it from the memory, you may need to run the following command from the Terminal command line (See the attached screenshot)

    $ qlmanage -r

Running the command to purge the older plugin version from the memory


Attention: To upgrade from 1.6.2 or earlier releases, please first delete the older version.  This is because, beginning from 1.7.0 release, the quick look plugin has been renamed from "DTITK_NIfTI_QuickLookPlugin.qlgenerator" to "DTITK_QuickLookPlugin.qlgenerator".


Usage & Demonstration

The standard Quick Look usage applies.  See the instructions provided by Apple for detail.  The following screenshots demonstrate the typical usages of the plugin.
