Extract patient from an CT

It is possible to extract the patient only from an CT, without mass (without mass where patient was lay down in order to exposed for CT) ? There is something VTK filter that could be used for this task ?

Answers


under some conditions it is possible to segment patient object from CT bed based on region growing segmentation. there is no class in VTK for this kind o segmentation. you can try ConnectedThresholdImageFilter in ITK or implement the algorithm yourself.


There is vtkImageSeedConnectivity which is a basic region growing algorithm in VTK. You'll probably need to preprocess the data before to use it
