Method and electronic device for calculating ratio of blood flow by vessel using vascular image

An electronic device comprising:

• a memory storing computer-readable instructions;
• and
• at least one processor connected to the memory and configured to execute the computer-readable instructions,
• wherein the computer-readable instructions, when executed by the at least one processor, are configured to cause the electronic device to:
• acquire at least one vascular image;
• classify, in the at least one vascular image, a plurality of vessels;
• extract geometric information of each of the plurality of vessels from the at least one vascular image;
• identify a ratio of blood-flow volumes by vessel based on a value extracted as the geometric information of each of the plurality of vessels and a reference value for the geometric information of each of the plurality of vessels, wherein the reference value are set based on values calculated from a plurality of subjects;
• and
• output, in association with at least one of the acquired at least one vascular image, an indicator associated with the ratio of blood-flow volumes by vessel.

A non-transitory computer-readable medium storing computer-readable instructions that, when executed by at least one processor, cause an electronic device to:

• acquire at least one vascular image;
• classify, in the at least one vascular image, a plurality of vessels;
• extract geometric information of each of the plurality of vessels from the at least one vascular image;
• identify a ratio of blood-flow volumes by vessel based on a value extracted as the geometric information of each of the plurality of vessels and a reference value for the geometric information of each of the plurality of vessels, wherein the reference value are set based on values calculated from a plurality of subjects;
• and
• output, in association with at least one of the acquired at least one vascular image, an indicator associated with the ratio of blood-flow volumes by vessel.
