ITK-SNAP

Step 1: Load the MRI scan of the brain into ITK-SNAP.

Step 2: Use manual segmentation tools to draw an initial contour around the tumor.

Step 3: Refine the segmentation using active contour methods to fit the tumor boundaries.

Step 4: Use the 3D cut-plane tool to smooth and correct the segmentation in 3D.

Step 1: Load the cardiac MRI or CT scan into ITK-SNAP.

Step 2: Use manual segmentation to delineate the left ventricle, right ventricle, and atria.

Step 3: Apply active contour segmentation to refine the boundaries of each chamber.

Step 4: Calculate the volumes of each chamber to assess cardiac function.

Step 1: Load the abdominal CT or MRI scan into ITK-SNAP.

Step 2: Use a combination of manual and semi-automatic segmentation to delineate the liver.

Step 3: Correct the segmentation using the 3D cut-plane tool.

Step 4: Calculate the liver volume and identify any lesions.

Step 1: Load the chest CT scan into ITK-SNAP.

Step 2: Use the region growing or active contour methods to segment the lungs.

Step 3: Manually correct any errors in the segmentation, especially near the hilum.

Step 4: Calculate lung volume and identify any nodules or abnormalities.

Step 1: Load the prostate MRI scan into ITK-SNAP.

Step 2: Use manual segmentation tools to delineate the prostate gland.

Step 3: Refine the segmentation using active contours.

Step 4: Calculate prostate volume and plan radiation therapy.
