Module Description

“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.

Tutorials

Below, we describe the Instructions Guide to use Calculator: 1. Open 3DSlicer and download “Calculator” using the “Extension Manager” 2. Import DICOM data from a CT-scan (better with non-enhanced series) 3. Open “Crop Volume” module - a. “Create a new annotation ROI” (Region Of Interest) - b. Size the ROI in x, y and z axes using axial (red), sagittal (yellow) and coronal (green) view in four-up disposition. - c. Create a new volume (name will be: “name cropped”) - d. Click “Apply” button 4. Open “Calculator” module: - a. Select volume: “name cropped” - b. Choose threshold (houndfields units) minimum and maximun to fit to the stone - c. If there are multiples stones select “split islands into segments” with a recommended “minimum size” of 40 voxels - d. Select a mode of treatment (laser source, core-diameter of laser fiber, laser settings and stone type) - e. Select “show 3D” if you want to visualize in 3D-view the segmented stone(s) - f. Click “Apply” button. A table will appear to show the segment’s name, volume (mm3) and time of lithotripsy (min)
