Abstract
According to an embodiment, a medical image processing device includes processing circuitry. The processing circuitry acquires an angiographic image of a subject. The processing circuitry detects branch points of blood vessels of the subject on the basis of the angiographic image. The processing circuitry generates a blood vessel diagram, which is a diagram showing a blood vessel distribution, on the basis of the branch points.
Claims14
A medical image processing device, comprising:
- processing circuitry configured to
- acquire an angiographic image of a subject;
- detect branch points of blood vessels of the subject based on the acquired angiographic image;
- generate a blood vessel diagram, which is a diagram showing a blood vessel distribution, based on the detected branch points;
- calculate a contrast delay period of time, which is a period of time required for a contrast medium to reach the blood vessel between the detected branch points, based on the angiographic image;
- and
- generate the blood vessel diagram in which the blood vessel is highlighted according to the calculated contrast delay period of time.
A medical image processing method to be executed using a computer, the medical image processing method comprising:
- acquiring an angiographic image of a subject;
- detecting branch points of blood vessels of the subject based on the acquired angiographic image;
- generating a blood vessel diagram, which is a diagram showing a blood vessel distribution, based on the detected branch points;
- calculating a contrast delay period of time, which is a period of time required for a contrast medium to reach the blood vessel between the detected branch points, based on the angiographic image;
- and
- generating the blood vessel diagram in which the blood vessel is highlighted according to the calculated contrast delay period of time.
A computer-readable non-transitory storage medium storing a program for causing a computer to:
