Title:
医用画像処理装置、超音波診断装置、及び医用画像処理プログラム
Document Type and Number:
Japanese Patent JP6734073
Kind Code:
B2
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.
