Abstract
A smallest enclosing body that encloses an abnormal region is set. A part of an organ, and the part belonging to the inside of an elliptic parabolic surface or a circular conic surface that circumscribes the set enclosing body, is extracted as a partial region. A region of a structure dominating the organ is extracted from the obtained medical image. A part of the organ, and the part including the abnormal region and being dominated by a part of the structure extending from a predetermined position in the extracted region of the structure toward the part of the organ including the abnormal region, is extracted as a dominance region. The partial region or the dominance region is determined as the excision region based on a predetermined excision region determination condition.
Claims12
A surgery-assistance apparatus that determines an excision region including an abnormal region of an organ to be removed, the apparatus comprising:
- a non-transitory computer readable medium storing computer-executable instructions;
- and
- a processor executing the instructions comprising:
- obtaining a medical image representing the organ;
- extracting a region of the organ from the obtained medical image;
- extracting the abnormal region from the extracted region of the organ;
- setting a smallest enclosing body that encloses the extracted abnormal region;
- extracting, as a partial region, a part of the organ, and the part belonging to the inside of an elliptic parabolic surface or a circular conic surface that circumscribes the set enclosing body;
- extracting a region of a structure dominating the organ from the obtained medical image;
- extracting, as a dominance region, a part of the organ, and the part including the abnormal region and being dominated by a part of the structure extending from a predetermined position in the extracted region of the structure toward the part of the organ including the abnormal region;
- and
- determining, based on a predetermined excision region determination condition, the partial region or the dominance region, as the excision region.
A surgery-assistance method that determines an excision region including an abnormal region of an organ to be removed, the method comprising:
- obtaining a medical image representing the organ;
- extracting a region of the organ from the obtained medical image;
- extracting the abnormal region from the extracted region of the organ;
- setting a smallest enclosing body that encloses the extracted abnormal region;
- extracting, by a computer, as a partial region, a part of the organ, and the part belonging to the inside of an elliptic parabolic surface or a circular conic surface that circumscribes the set enclosing body;
- extracting, by the computer, a region of a structure dominating the organ from the obtained medical image;
- extracting, by the computer, as a dominance region, a part of the organ, and the part including the abnormal region and being dominated by a part of the structure extending from a predetermined position in the extracted region of the structure toward the part of the organ including the abnormal region;
- and
- determining, by the computer, based on a predetermined excision region determination condition, the partial region extracted by the partial region extraction unit or the dominance region extracted by the dominance region extraction unit, as the excision region;
- and displaying the determined partial region on a display.
A non-transitory computer-readable recording medium storing therein a surgery-assistance program that determines an excision region including an abnormal region of an organ to be removed, the program comprises a plurality of computer-executable instructions, wherein the instructions comprise:
- obtaining a medical image representing the organ;
- extracting a region of the organ from the obtained medical image;
- extracting the abnormal region from the extracted region of the organ;
- setting a smallest enclosing body that encloses the extracted abnormal region;
- extracting, as a partial region, a part of the organ, and the part belonging to the inside of an elliptic parabolic surface or a circular conic surface that circumscribes the set enclosing body;
- extracting a region of a structure dominating the organ from the obtained medical image;
- extracting, as a dominance region, a part of the organ, and the part including the abnormal region and being dominated by a part of the structure extending from a predetermined position in the extracted region of the structure toward the part of the organ including the abnormal region;
- and
- determining, based on a predetermined excision region determination condition, the partial region or the dominance region, as the excision region.
