Medical report generation apparatus, method and program
A medical report generation apparatus includes a key image selection unit that selects, as a key image representing a diagnostic characteristic feature, a slice image generated based on three-dimensional medical image data obtained by imaging a subject, a selected position input unit that inputs a selected position in the key image, a supplementary image determination unit that determines, based on the key image and the selected position, a slice image that includes the selected position and represents a cross section different from a cross section represented by the key image, as a supplementary image, in the three-dimensional medical image data, and a medical report generation unit that generates a medical report including the key image and information for identifying the supplementary image.
1. A medical report generation apparatus comprising:
a key image selection unit that selects, as a key image representing a diagnostic characteristic feature, a slice image generated based on three-dimensional medical image data obtained by imaging a subject;
a selected position input unit that accepts a position input by a user on the key image and that inputs the accepted position as a selected position in the key image;
an abnormal shadow extraction unit that extracts an abnormal shadow within a predetermined neighborhood range from the selected position;
a supplementary image determination unit that moves the selected position into the extracted abnormal shadow based on the key image and the selected position in case that the abnormal shadow is extracted and that determines a slice image that includes the moved selected position and represents a cross section different from a cross section represented by the key image, as a supplementary image in the three-dimensional medical image data; and
a medical report generation unit that generates a medical report including the key image and information for identifying the supplementary image.
2. A medical report generation apparatus, as defined in claim 1 , wherein the key image is an axial image, and the supplementary image is a coronal image.
3. A medical report generation apparatus, as defined in claim 1 , wherein the supplementary image determination unit determines the supplementary image in such a manner that the inclination of a cross section represented by the supplementary image differs based on the selected position.
4. A medical report generation apparatus, as defined in claim 3 , the apparatus further comprising:
a region extraction unit that extracts a region including the input selected position from the three-dimensional medical image data,
wherein the supplementary image determination unit determines the supplementary image in such a manner that the inclination of the cross section represented by the supplementary image differs based on the extracted region.
5. A medical report generation apparatus, as defined in claim 4 , wherein the supplementary image determination unit determines a sagittal image as the supplementary image when the extracted region is curved toward the front direction of the subject and the key image is not a sagittal image.
6. A medical report generation apparatus, as defined in claim 1 , wherein a multiprojection volume reconstruction image is determined as the supplementary image.
7. A medical report generation apparatus, as defined in claim 1 , the apparatus further comprising:
an image generation unit that generates the supplementary image based on the information identifying the supplementary image; and
a display unit that displays the medical report including the generated supplementary image.
8. A medical report generation method comprising the steps of:
selecting, as a key image representing a diagnostic characteristic feature, a slice image generated based on three-dimensional medical image data obtained by imaging a subject;
accepting a position input by a user on the key image and inputting the accepted position as a selected position in the key image;
extracting an abnormal shadow within a predetermined neighborhood range from the selected position;
moving the selected position into the extracted abnormal shadow, based on the key image and the selected position in case that the abnormal shadow is extracted and determining a slice image that includes the moved selected position and represents a cross section different from a cross section represented by the key image, as a supplementary image, in the three-dimensional medical image data; and
generating a medical report including the key image and information for identifying the supplementary image.
9. A non-transitory computer-readable recording medium stored therein a program for causing a computer to function as:
a key image selection unit that selects, as a key image representing a diagnostic characteristic feature, a slice image generated based on three-dimensional medical image data obtained by imaging a subject;
a selected position input unit that accepts a position input by a user on the key image and that inputs the accepted position as a selected position in the key image;
an abnormal shadow extraction unit that extracts an abnormal shadow within a predetermined neighborhood range from the selected position;
a supplementary image determination unit that moves the selected position into the extracted abnormal shadow, based on the key image and the selected position in case that the abnormal shadow is extracted and that determines a slice image that includes the moved selected position and represents a cross section different from a cross section represented by the key image, as a supplementary image, in the three-dimensional medical image data; and
a medical report generation unit that generates a medical report including the key image and information for identifying the supplementary image.
