Abstract
A method, apparatus and device for correcting a vascular pressure difference are disclosed. An intracavity imaging technology is used to acquire images in a main branch blood vessel. A plurality of blood vessel cross sections are obtained using the images, and an area of a cutting plane of a side branch blood vessel is directly calculated by using the blood vessel cross sections. The blood vessel difference is then corrected by using the cutting area.
