How to make AI software to mapping cortical bone thickness

Hello, I am a dentist and new user in this amazing software
I want to make a artificial intelligence for mapping of cortical bone thickness
Actually it is my thesis and this will be my research work for my master degree, I am lost and I dont konw how to strat
I know segmentation of bone is the first step, okay what next
How to determine every single point as thickness in DICOM file , It is impossible to make all of them manually
will I have to segment cortical bone only or cortical bone with spongy bone?
what if I convert dicom file into jpg ?
I need your help please
NB the DICOM file from CBCT not CT
