<div>Hi Jiangshan, <br>If you want to get some slices from a data volume (for example imageData), you can use vtkExtractVOI. </div>
<div>First create extractVOI object</div>
<div>Second set the input data (imageData)</div>
<div>Third set the region you want to extract using selectVOI method</div>
<div>Fourth call update method of extractVOI object</div>
<div>Finally getOutput returns the image in a imageData object.</div>
<div> </div>
