Abstract: Images where the vascular walls are automatically divided are obtained by obtaining two MRI images that reflect different properties of the blood vessel and obtaining the difference between the two images. This can image both the vascular inner and the outer walls, thereby obtaining the exact size of the blood vessel, and the thickness between the vascular inner and outer walls. Therefore, it is possible to stably perform the operation using a stent with an accurate size during the stent procedure.
