Abstract

Extracting a luminal or line-like three-dimensional structure from a three-dimensional image of a target object, then generating a projection image by projecting a portion of the entirety of the three-dimensional structure on a cross-sectional image of the target object intersecting the three-dimensional structure, the portion being a portion located within a range of a predetermined thickness from a cross-section represented by the cross-sectional image or a portion located within a range of a predetermined distance from a position where the three-dimensional structure is intersecting the cross-sectional image, and displaying the generated projection image.

Claims

1. An image display method comprising the steps of:

extracting a luminal or line-like three-dimensional structure from a three-dimensional image of a target object;

generating a projection image by projecting a portion of the entirety of the three-dimensional structure on a cross-sectional image of the target object intersecting the three-dimensional structure, the portion being a portion located within a range of a predetermined thickness from a cross-section represented by the cross-sectional image; and

displaying the generated projection image,

wherein the step of generating the projection image is a step of generating a projection image by projecting only a part of the entirety of the portion of the three-dimensional structure located within the range of the predetermined thickness, the part continuing from a section of the three-dimensional structure intersecting the cross-sectional image within the range.

2. An image display apparatus comprising:

a structure extraction means for extracting a luminal or line-like three-dimensional structure from a three-dimensional image of a target object;

a projection image generation means for generating a projection image by projecting a portion of the entirety of the three-dimensional structure on a cross-sectional image of the target object intersecting the three-dimensional structure, the portion being a portion located within a range of a predetermined thickness from a cross-section represented by the cross-sectional image; and

an image display means for displaying the generated projection image,

wherein the projection image generation means is a means for generating the projection image by projecting only a part of the entirety of the portion of the three-dimensional structure located within the range of the predetermined thickness or distance, the part continuing from a section of the three-dimensional structure intersecting the cross-sectional image within the range.

3. A non-transitory computer readable storage medium on which a program for causing a computer to perform the following steps:

extracting a luminal or line-like three-dimensional structure from a three-dimensional image of a target object;

generating a projection image by projecting a portion of the entirety of the three-dimensional structure on a cross-sectional image of the target object intersecting the three-dimensional structure, the portion being a portion located within a range of a predetermined thickness from a cross-section represented by the cross-sectional image; and

displaying the generated projection image,

wherein the step of generating the projection image is a step of generating a projection image by projecting only a part of the entirety of the portion of the three-dimensional structure located within the range of the predetermined thickness or distance, the part continuing from a section of the three-dimensional structure intersecting the cross-sectional image within the range.

4. An image display method, comprising the steps of:

extracting a luminal or line like three dimensional structure from a three dimensional image of a target object;

generating a projection image by projecting a portion of the entirety of the three dimensional structure on a cross sectional image of the target object intersecting the three dimensional structure, the portion being a portion located within a range of a predetermined distance from a cross section represented by the cross sectional image; and

displaying the generated projection image;

the generation of the projection image being performed by projecting only a part of the entirety of the portion of the three-dimensional structure located within the range of the predetermined distance, the part continuing from a section of the three-dimensional structure intersecting the cross-sectional image within the range.

5. An image display apparatus, comprising:

a structure extraction means for extracting a luminal or line like three dimensional structure from a three dimensional image of a target object;

a projection image generation means for generating a projection image by projecting a portion of the entirety of the three dimensional structure on a cross sectional image of the target object intersecting the three dimensional structure, the portion being a portion located within a range of a predetermined distance from a cross section represented by the cross sectional image; and

an image display means for displaying the generated projection image;

the projection image generation means generating the projection image by projecting only a part of the entirety of the portion of the three-dimensional structure located within the range of the predetermined distance, the part continuing from a section of the three-dimensional structure intersecting the cross-sectional image within the range.

6. A non transitory computer readable medium, having stored therein a program that causes a computer to execute an image display method, comprising the procedures of:

extracting a luminal or line like three dimensional structure from a three dimensional image of a target object;

generating a projection image by projecting a portion of the entirety of the three dimensional structure on a cross sectional image of the target object intersecting the three dimensional structure, the portion being a portion located within a range of a predetermined distance from a cross section represented by the cross sectional image; and

displaying the generated projection image;

the generation of the projection image being performed by projecting only a part of the entirety of the portion of the three-dimensional structure located within the range of the predetermined distance, the part continuing from a section of the three-dimensional structure intersecting the cross-sectional image within the range.
