Abstract
A medical-image processing apparatus according to an embodiment includes processing circuitry. The processing circuit acquires an initial value of an outline corresponding vector that corresponds to an outline of a subject included in medical image data. The processing circuitry updates the outline corresponding vector based on a derivative that is acquired by differentiating a cost function with respect to the outline corresponding vector by the outline corresponding vector, and on the initial value of the outline corresponding vector.
Claims11
A medical-image processing apparatus comprising processing circuitry configured:
- to acquire an initial value of an outline corresponding vector that corresponds to an outline of a subject included in medical image data, and
- to update the outline corresponding vector based on a derivative that is acquired by differentiating a cost function with respect to the outline corresponding vector by the outline corresponding vector, and on the initial value of the outline corresponding vector.
An ultrasonic diagnostic apparatus comprising:
- a scanner configured to scan a subject body by using ultrasonic waves, and collects reflected wave data;
- and
- processing circuitry configured;
- to acquire an initial value of an outline corresponding vector that corresponds to an outline of a subject included in medical image data generated by the reflected wave data, and
- to update the outline corresponding vector based on a derivative acquired by differentiating a cost function with respect to the outline corresponding vector by the outline corresponding vector, and on the initial value of the outline corresponding vector.
A medical-image processing method comprising:
- acquiring an initial value of an outline corresponding vector that corresponds to an outline of a subject included in medical image data;
- and
- updating the outline corresponding vector based on a derivative that is acquired by differentiating a cost function with respect to the outline corresponding vector by the outline corresponding vector, and on the initial value of the outline corresponding vector.
