What software can CT two-dimensional images be converted into 3d models?

There are two ways.

One is to use professional interactive medical image control software. There is a software called MIMICS.

People's Military Medical Publishing House published a book called Clinical Application of Mimics Software. Introduction to computer-aided surgery technology, in which the software is introduced in detail. As I am not a medical student, my knowledge in this field is limited. The landlord can buy a book to read, and can buy it online. Some software tutorials can also be searched online.

Another method is to use commonly used three-dimensional animation software, such as MAYA, 4D cinema and 3DMAX. Only this method can be used for modeling, but it may be insufficient in medical research.
