MRI Sustentorial brain extraction with MATLAB

Dear all,

I need to extract the sustentorial part of the brain from ASL perfusion MRI data to calculate perfusion. Is there any function or code on MATLAB that could help me?

Your help is well appreciated.

Best,

Abir.

The more specific your question, the less likely it is there already exists a turn-key solution.

Presumably you searched on Google for a few key phrases, so you already know whether there are specific solutions.

What is your actual question?

Have a read here and here. It will greatly improve your chances of getting an answer.

look for Mathworks Image Processing Toolbox to get access to the source data probably in DICOM format

• dicomread | dicominfo | dicomreadVolume
• DICOM Browser

Thank you for your responses.

In fact, I have patients who are being treated for brain tumors in the posterior fossa, I want to measure the perfusion in the supratentorial part of the brain to quantify the effect of radiotherapy. The problem is that I am still a beginner with MATLAB, and the automatic segmentation does not allow me to have only the supratentorial part. So I don't know if there are other functions that allow me to segment the brain and have only the supratentorial part, to use it later as a mask to calculate the perfusion.

Knowing that my volumes are in nifti and not in DICOM format.
