1. Field of the Invention
The present invention relates to a medical image display control device, a method of operation for the same, and a medical image display control program for displaying the internal tissue of a subject so as to be superimposed on a three-dimensional image of the subject.
2. Description of the Related Art
In the related art, the planning of actual surgery or the like has been performed using a three-dimensional image captured before surgery. When performing such surgical planning, the internal tissue, such as blood vessels at the back of the skin tissue or the bone tissue, needs to be visualized in some cases.
Specifically, for example, in the case of performing craniotomy, only things on the surface are visible when performing actual surgery since the head has a layer structure of a skin region, a bone region, and a brain region from the surface. Therefore, when incising the skin, blood vessels under the skin are the important tissue for the surgery. In addition, when opening the bone, brain veins or brain arteries under the bone are the important tissue for the surgery.
In such a case, in general, the internal tissue, such as blood vessels, can be displayed by extracting the skin tissue or the bone tissue and adjusting the opacity or the attenuation.
In order to display the internal tissue, JP2007-325629A has proposed to display a three-dimensional image of the internal tissue excluding, for example, a region of the skin tissue by setting a predetermined range from the surface of the subject as a removal layer and constructing a three-dimensional image from which the removal layer has been removed.
