Medical image processing apparatus, medical image processing method, and system
A medical image processing apparatus for visualizing a tissue includes: a memory; and a processor configured to execute a process. The process includes: acquiring volume data including the tissue; setting a cut surface for cutting the tissue in the volume data; and first performing processing relating to visualization of the tissue. The first performing includes: second performing rendering that causes ray attenuation on the volume data to generate a rendering image including the tissue cut along the cut surface; and displaying on a display unit display information including the rendering image in which a contour line of the tissue on the cut surface is highlighted.
1. A medical image processing apparatus for visualizing a tissue, comprising:
a memory; and
a processor configured to execute a process, the process comprising:
acquiring volume data including the tissue;
setting a cut surface for cutting the tissue in the volume data; and
first performing processing relating to visualization of the tissue,
wherein the first performing comprises:
second performing rendering that causes ray attenuation on the volume data to generate a rendering image including the tissue cut along the cut surface; and
displaying on a display unit display information including the rendering image in which a contour line of the tissue on the cut surface is highlighted.
2. The medical image processing apparatus according to claim 1 , wherein
the setting comprises setting the cut surface based on a mask boundary surface which is a boundary between a mask region including voxels to be rendered among a plurality of voxels included in the volume data and a non-mask region including voxels not to be rendered, and
the first performing comprises displaying the rendering image generated based on voxel values that does not include voxel values of voxels of the non-mask region and that includes voxel values of voxels included in the mask region.
3. The medical image processing apparatus according to claim 1 , wherein
the tissue is a tubular tissue.
4. The medical image processing apparatus according to claim 3 , wherein
the tubular tissue is running through an organ.
5. The medical image processing apparatus according to claim 4 , wherein
the first performing comprises displaying on a display unit display information including the rendering image in which a contour line of the organ on the cut surface and a contour line of the tubular tissue on the cut surface are highlighted.
6. The medical image processing apparatus according to claim 3 , wherein
the first performing comprises displaying on the display unit display information including the rendering image in which a direction of the tubular tissue is indicated.
7. The medical image processing apparatus according to claim 3 , wherein
the first performing comprises displaying on the display unit display information including the rendering image in which a contour line of the tubular tissue on the cut surface is offset from the cut surface for highlighting.
8. The medical image processing apparatus according to claim 1 , wherein
the tissue is an organ.
9. The medical image processing apparatus according to according to claim 1 , wherein
the first performing comprises highlighting an inside surface of the contour line on the cut surface to display the rendering image.
