The purpose of this segmentation is to have the student move through the image series and correlate the different images of the left and right limb with the standard radiograph projections. In this example, the LM projection actually matches up with the bones in image #7 rather than the actual lateral/medial image (#9). Having the mirror images of the right and left limb helps the student "flatten" the 3D structure down to a single plane which is helpful with radiographs.
Many of the pages in this lesson will use a sequence of images. You can recognize an image series by the number series and arrows underneath an image. To learn how to best optimize your use of these image series watch the YouTube video link below. The salient points of this video:
1. To move through the image series, USE YOUR FORWARD AND REVERSE KEYBOARD ARROWS. Do NOT use your mouse if at all possible.
2. When you first load the page it will often take about 15 seconds or so for larger image sequences to load. Evidence all of the images have not yet loaded are "disappearing" images when you attempt to navigate through the series with the keyboard arrows.
3. Once all of the images have loaded you are ready to go! Proceed forward and backward at whatever speed you desire, noting important objectives. To proceed at "live speed" continuously press on an arrow.
4. If you desire you can increase the display size of an image series by changing your web browser zoom.
5. Once you have loaded your sequence it will be retained in your cache. When you return to that page there will not be a delay in loading (until you delete your cache or hit a complete page refresh [i.e. F5]).
6. The time it takes to load a series depends on:
++++A. The quality of your internet connection
++++B. The length of the image series. Some CT scans might take 30-45 seconds.
