Module Description
Calculate image and volume properties using a label map and a gray scale image.
Use Cases
The module is fairly simple. Just select a background volume and a label volume (for example, as created using the Editor Module) and click Apply.
The volumes of the table show:
- Label there is one row for each unique value in the label volume
- Count is the number of pixels in the label volume that have this value
- Volume mm^3 is the product of the pixel spacings (volume per pixel) times the Count in cubic millimeters
- Volume cc is the product of the pixel spacings (volume per pixel) times the Count in cubic centimeters (there are 1000 mm^3 per cc)
- Min, Max, Mean, StdDev Statistics on the grayscale pixel values at the locations that correspond to the label value.
- The Save Button can be used to create a text file of the contents of the calculated table. The results are stored in comma separated value format, with the default .csv file extension. This format can easily be opened in spreadsheet programs for further analysis or plotting. Example file contents are shown below.
