Abstract
A processor is configured to derive a virtual monochromatic image at an energy level at which contour lines of pixel values are parallel to a longitudinal direction of a distribution of signal values of a first base substance and a second base substance in a scatter diagram in which the first base substance and the second base substance serve as axes, and derive a substance type image representing types of a plurality of substances in the virtual monochromatic image by using substance decomposition information derived based on a distribution of the signal values in a direction intersecting a direction in which the pixel values of the virtual monochromatic image change in the scatter diagram.
Claims9
An information processing apparatus comprising:
- a processor,
- wherein the processor is configured to:
- derive a virtual monochromatic image at an energy level at which contour lines of pixel values are parallel to a longitudinal direction of a distribution of signal values of a first base substance and a second base substance in a scatter diagram in which the first base substance and the second base substance serve as axes;
- and
- derive a substance type image representing types of a plurality of substances in the virtual monochromatic image by using substance decomposition information derived based on a distribution of the signal values in a direction intersecting a direction in which the pixel values of the virtual monochromatic image change in the scatter diagram.
An information processing method comprising:
- via a computer,
- deriving a virtual monochromatic image at an energy level at which contour lines of pixel values are parallel to a longitudinal direction of a distribution of signal values of a first base substance and a second base substance in a scatter diagram in which the first base substance and the second base substance serve as axes;
- and
- deriving a substance type image representing types of a plurality of substances in the virtual monochromatic image by using substance decomposition information derived based on a distribution of the signal values in a direction intersecting a direction in which the pixel values of the virtual monochromatic image change in the scatter diagram.
A non-transitory computer-readable storage medium that stores an information processing program causing a computer to execute:
- a procedure of deriving a virtual monochromatic image at an energy level at which contour lines of pixel values are parallel to a longitudinal direction of a distribution of signal values of a first base substance and a second base substance in a scatter diagram in which the first base substance and the second base substance serve as axes;
- and
- a procedure of deriving a substance type image representing types of a plurality of substances in the virtual monochromatic image by using substance decomposition information derived based on a distribution of the signal values in a direction intersecting a direction in which the pixel values of the virtual monochromatic image change in the scatter diagram.
