Is there a program for automatic segmentation of a CT scan?

Dear all,

I would like to automate the segmentation of CT scans. Especially I would like to do segmentation of thorax (separate bones from tissue). I would like to automate this, because I would like to use for another dozens CT scans, which would be very complicated to do manually. I tried find some programs or functions, but I didn´t successful.

Can you advise me? Thank you for your answers.

Automatic segmentation is generally very difficult. In this case, you could try to use the fact that bone tissue will have a much higher HU value than the rest of the body, so you may get away with a simple threshold.

boneMask=CT<2000;

Matlab has a built-in App called volumeViewer starting in R2017a that looks pretty good.

For earlier versions, check the Matlab FEX.
