Abstract
A virtual ray makes one revolution around an imaginary path with an umbrella-like elevation angle θ kept constant with respect to the imaginary path to thereby generate a projected image. When the virtual ray is radiated obliquely, a shaded portion of an inner wall surface of a tubular tissue can be observed clearly.
Claims22
An image processing method for visualizing information of a living body near an imaginary path which is a center line of a subject of observation, said image processing method comprising:
- determining a ray direction of a virtual ray according to an elevation angle which is an angle between the virtual ray at a ray basis point and a path direction of said path at a ray start point;
- projecting said virtual ray according to said ray direction passing the ray basis point thereby to generate a projected image;
- and
- visualizing the living body information based on said projected image.
A computer-readable medium including a processor connected to at least one of an image processing portion, a volume data generating portion, an operating portion and a display device, said processor contains a set of instructions for image processing, said set of instructions comprising:
- determining a ray direction of a virtual ray according to an elevation angle which is an angle between the virtual ray at a ray basis point and a path direction of said path at a ray start point;
- projecting said virtual ray according to said ray direction passing the ray basis point thereby to generate a projected image;
- and
- visualizing the living body information based on said projected image.
