For the purpose of selection, lines (segments) are delimited by the end of a line and/or a line branching from it.

The selection of the lines (vessel segments in a vasculature) is performed entirely with mouse clicks. Volume Calculator has taken its final result - a Java 3D representation of the analyzed image - and asked the 3D Viewer to display it. After a successful run, the plugin will display the Volume Calculator window (Figure 2.) This window is actually the 3D Viewer plugin. Processing begins immediately its progress is shown in the status bar. When run, it will take the current image as input. The Volume Calculator is located at Plugins › Analyze in the Fiji menu. If it can not be analyzed then oftentimes adjusting the threshold can make it “analyzable”.

A second test can be performed by taking this skeleton image and applying to the AnalyzeSkeleton plugin to see if it can be analyzed. You can pretest this image by running the image through the Skeletonize3D plugin. These settings are often determined by the nature of the image, for example, its noisiness, or by what features you wish to retain. If your image is not binary then it must be thresholded in order for the first stage in the Volume Calculator to work. This MRA consists of 150 slices, each 512 X 512 in size. Figure 1 shows a 3D rendering of the example MRA. But be aware of the plugin’s limitation: see the Introduction above. This MRA is of the hindlimb vasculature of a mouse and was performed in vivo. A Magnetic Resonance Angiogram Magnetic resonance angiography|(MRA) is used as an example image.

The section explains how to use Volume Calculator.

Skeletonize3D for performing the skeletonization,.

Volume Calculator uses three Fiji plugins: Hence, it is suggested that users first check their images with these two plugins. This possibility is determined by the following requirement: the plugin is configured to work best with images that can be read and analyzed by the Skeleton 3D and Analyze 3D plugins. Although Volume Calculator was developed for quantification in a mouse hindlimb ischemia experiment, it should be useful for the volume measurement of any network. The Volume Calculator plugin is designed to let users measure the volumes of arbitrary segments of blood vessels by selecting them directly from a 3D image.
