The Canine Muscle Atlas Project
Loading, Viewing, and Interacting with the Canine Muscle Atlas
3D model
![Page 2: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/2.jpg)
Getting started
• Download the MuscleAtlas3Dmodel.zip file.– Extract all files and note where they are saved
• Download and install the latest stable release of 3D Slicer from: http://slicer.org/pages/Special:SlicerDownloads– 3D Slicer is large and the download time will depend on
the connectivity method
– Open the 3D Slicer program

Click “File” and select “Load Scene”
![Page 4: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/4.jpg)
Find the folder containing the files that you downloaded and unzipped.
Open the CanineMuscleAtlas.mrml file(ignore the _CanineMuscle.mrml file)
![Page 5: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/5.jpg)
The skeletal model should automatically display with the right limb muscles
displayed; this may take a few minutes
![Page 6: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/6.jpg)
Reorienting the model
Clicking on the axis labels will result in standardized orthogonal views
![Page 7: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/7.jpg)
Changing the display window
To change the background color, hide the 3D cube or hide the 3D axis labels, select the pop-ups activated by clicking the eye.
![Page 8: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/8.jpg)
Changing the structures on display
Click on the stack of cameras to select muscles grouped by function (e.g. stifle extensors) or muscles grouped by innervation (e.g. by femoral nerve). There will be a delay when changing between scenes.
![Page 9: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/9.jpg)
Muscles in this group are indicated by an “open” eye in the MRML tree.

Selective display
![Page 11: The Canine Muscle Atlas Project Loading, Viewing, and Interacting with the Canine Muscle Atlas 3D model.](https://reader035.fdocuments.us/reader035/viewer/2022062305/56649e865503460f94b89b9a/html5/thumbnails/11.jpg)
Selective display
For example, by checking the eye next to the quadriceps femoris muscle, it will be displayed on the skeleton.
