“Calculator” consists in a volumetric evaluation of kidney stones and also provides information on surgical duration. Moreover, it provides the estimated time of lithotripsy and consequently the operative time. It provides in a few seconds a 3D view of the stone(s) and axial, coronal and sagittal views with CT-scan DICOMs.
Module Description
Below, we describe the Instructions Guide to use Calculator:
- Open 3DSlicer and download “Calculator” using the “Extension Manager”
- Import DICOM data from a CT-scan (better with non-enhanced series)
- Open “Crop Volume” module
* “Create a new annotation ROI” (Region Of Interest) * Size the ROI in x, y and z axes using axial (red), sagittal (yellow) and coronal (green) view in four-up disposition. * Create a new volume (name will be: “name cropped”) * Click “Apply” button
- Open “Calculator” module:
* Select volume: “name cropped” * Choose threshold (houndfields units) minimum and maximun to fit to the stone * If there are multiples stones select “split islands into segments” with a recommended “minimum size” of 40 voxels * Select a mode of treatment (laser source, core-diameter of laser fiber, laser settings and stone type) * Select “show 3D” if you want to visualize in 3D-view the segmented stone(s) * Click “Apply” button. A table will appear to show the segment’s name, volume (mm3) and time of lithotripsy (min)
