Abstract
An image processing apparatus obtains information representing a region of interest from a three-dimensional image, and, when a projection direction of the three-dimensional image is changed, based on the projection direction and the information representing the region of interest, determines a parameter that indicates a thickness of projection used in projection processing. The image processing apparatus uses the determined parameter to generate a projection image by applying projection processing toward the projection direction to the three-dimensional image.
Claims19
An image processing apparatus, comprising:
- an obtaining unit configured to obtain, from a three-dimensional image, information that represents a region of interest;
- a changing unit configured to change a projection direction of the three-dimensional image;
- a projecting unit configured to generate a projection image by applying projection processing toward the projection direction to the three-dimensional image;
- and
- a determining unit configured to determine, in accordance with a change of the projection direction by the changing unit and based on the information that represents the region of interest and the changed projection direction, a parameter that indicates a thickness of a projection used in the projection processing.
An image processing apparatus, comprising:
- an obtaining unit configured to obtain, from a three-dimensional image, information that represents a region of interest;
- a setting unit configured to set a plurality of projection directions with respect to the three-dimensional image;
- a projecting unit configured to generate a projection image by applying projection processing in each of the plurality of projection directions to the three-dimensional image;
- and
- a determining unit configured to, for each of the plurality of projection directions set by the setting unit, determine, based on the projection direction and the information representing the region of interest, a parameter indicating a thickness of projection used in the projection processing.
A method of controlling an image processing apparatus, the method comprising:
- obtaining, from a three-dimensional image, information that represents a region of interest;
- changing a projection direction of the three-dimensional image;
- generating a projection image by applying projection processing toward the projection direction to the three-dimensional image;
- and
- determining, in accordance with a change of the projection direction and based on the information that represents the region of interest and the changed projection direction, a parameter that indicates a thickness of a projection used in the projection processing.
A method of controlling an image processing apparatus, the method comprising:
- obtaining, from a three-dimensional image, information that represents a region of interest;
- setting a plurality of projection directions with respect to the three-dimensional image;
- generating a projection image by applying projection processing in each of the plurality of projection directions to the three-dimensional image;
- and
- for each of the plurality of projection directions that are set, determining, based on the projection direction and the information representing the region of interest, a parameter indicating a thickness of projection used in the projection processing.
