Abstract
In part, the disclosure relates to intravascular data collection systems and the software-based visualization and display of intravascular data relating to detected side branches and side branch obstruction. An estimate of side branch diameter can be made based on a vessel profile or a maximum diameter of a vessel at a distal and proximal location relative to the side branch. A amount of side branch obstruction may be determined by comparing an observed side branch diameter with in the image data with the estimated side branch diameter. In addition, an amount of blood flow obstruction may also be determined.
Claims18
A method of identifying vascular structure, the method comprising the steps of:
- receiving, by one or more processors, image data for a blood vessel;
- identifying a side branch from the blood vessel within the image data;
- identifying an observed diameter of the side branch based on the image data;
- obtaining, by the one or more processors, a representation of vessel diameters at a distal segment and at a proximal segment of the blood vessel relative to the side branch;
- determining, by the one or more processors, an estimated diameter of the side branch based on the representation of vessel diameters;
- and
- determining an amount of branch obstruction based on a comparison of the estimated diameter with the observed diameter.
A system for identifying vascular structure, the system comprising one or more memories in communication with one or more processors, wherein the one or more processors are configured to:
- receive image data for a blood vessel;
- identify a side branch from the blood vessel within the image data;
- identify an observed diameter of the side branch based on the image data;
- obtain a representation of vessel diameters at a distal segment and at a proximal segment of the blood vessel relative to the side branch;
- determine an estimated diameter of the side branch based on the representation of vessel diameters;
- and
- determine an amount of branch obstruction based on a comparison of the estimated diameter with the observed diameter.
A non-transitory computer-readable medium storing instructions executable by one or more processors for performing a method comprising:
- receiving image data for a blood vessel;
- identifying a side branch from the blood vessel within the image data;
- identifying an observed diameter of the side branch based on the image data;
- obtaining a representation of vessel diameters at a distal segment and at a proximal segment of the blood vessel relative to the side branch;
- determining an estimated diameter of the side branch based on the representation of vessel diameters;
- and
- determining an amount of branch obstruction based on a comparison of the estimated diameter with the observed diameter.
