Image processing device, image processing system, image display method, and image processing program

An image display method for generating and updating three-dimensional data representing a biological tissue based on tomographic data of the biological tissue acquired by a sensor that acquires the tomographic data while moving through a lumen of the biological tissue, and causing a display to display the three-dimensional data as a three-dimensional image, the image processing method comprising:

• coloring, in the three-dimensional image, at least a voxel representing an inner surface of the biological tissue or a voxel that is adjacent to the voxel representing the inner surface and that represents the lumen among a first voxel group corresponding to a cross section indicated by tomographic data newly acquired by the sensor, in a manner of being distinguished from a second voxel group corresponding to another cross section of the biological tissue;
• combining a first graphic element representing a moving range of the sensor with a second graphic element representing a position of the sensor and cause the display to display the combination together with the three-dimensional image;
• and
• causing the display to display the first graphic element in a direction in which a longitudinal direction of the lumen in the three-dimensional image and a long axis direction of the first graphic element are parallel to each other.

A non-transitory computer readable medium storing an image processing program which, when executed by a computer, generates and updates three-dimensional data representing a biological tissue based on tomographic data of the biological tissue acquired by a sensor that acquires the tomographic data while moving through a lumen of the biological tissue, and causes a display to display the three-dimensional data as a three-dimensional image, and performs processing comprising:

• coloring, in the three-dimensional image, at least a voxel representing an inner surface of the biological tissue or a voxel that is adjacent to the voxel representing the inner surface and that represents the lumen among a first voxel group corresponding to a cross section indicated by tomographic data newly acquired by the sensor, in a manner of being distinguished from a second voxel group corresponding to another cross section of the biological tissue;
• combining a first graphic element representing a moving range of the sensor with a second graphic element representing a position of the sensor and cause the display to display the combination together with the three-dimensional image;
• and
• causing the display to display the first graphic element in a direction in which a longitudinal direction of the lumen in the three-dimensional image and a long axis direction of the first graphic element are parallel to each other.
