<div dir="ltr">Matias,<div><br></div><div>Open the DICOM stack in an image viewer (such as Slicer), and identify a threshold </div><div>value of intensity that will separate the skin from the air outside the patient.</div>
<div><br></div><div><br></div><div>With that number at hand, </div><div>you an try the following example:</div><div><a href="http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/BinaryThresholdImageFilter">http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/BinaryThresholdImageFilter</a><br>

Is there a way to obtain the points cloud from a stack of DICOM images using ITK? (I have a directory with the images). Can you help me with some code?<br>
