APPARATUS AND METHOD FOR DETERMINING LESION SIMILARITY OF MEDICAL IMAGE

摘要

Disclosed are an apparatus and a method for determining lesion similarity of a medical image. The apparatus for determining lesion similarity according to one aspect of the present invention may comprise: an image input unit for receiving a reference image comprising a reference lesion area, and a target image comprising a target lesion area; and a similarity determination unit for determining similarity of the reference lesion area and the target lesion area by applying an advantage weight, which increases as getting closer to the center of the reference lesion area, to pixels included in a first area of the reference lesion area, and a penalty weight, which increases as getting farther away from the reference lesion area, to pixels included in a second area of the target lesion area.

主权项

1. An apparatus for determining a lesion similarity, the apparatus comprising:
an image input section configured to receive input of a reference image including a reference lesion area, and a target image including a target lesion area; and a similarity determiner configured to determine a similarity between the reference lesion area and the target lesion area by applying an advantage weighted value to a pixel included in a first area of the target lesion area, the advantage weighted value increasing as the pixel of the first area gets closer to a center of the reference lesion area, and by applying a penalty weighted value to a pixel included in a second area of the target lesion area, the penalty weighted value increasing as the pixel of the second area gets farther from the reference lesion area.
