Image processing method and computer readable medium for image processing
First Claim
1. An image processing method for visualizing volume data of tissue, the image processing comprising:
- receiving the volume data, wherein the volume data is obtained based on a scan of the tissue using one of a tomographic scanner and a magnetic resonance imaging scanner;
determining a reference lane intersecting a spherical surface;
determining respective values in the volume data on outside of the intersection of the reference plane and one-side of the spherical surface;
rendering an image by using the determined values; and
rotating the reference plane at the center of the spherical surface.

Abstract
An intestine is cut by a cross section of a spherical surface or a combination of a plane and a spherical surface, and voxel values on the cross section are projected onto a projection plane in parallel, whereby a cross-sectional image of the intestine is created. Unlike a CPR image, the image of the spherical portion is projected without being extended. If the radius of the spherical surface is increased, the depth toward a screen can be seen and thus perspective of the inside of the observation object can be understood. On the other hand, if the radius of the spherical surface is lessened, the cut surface of the observation object is displayed as flat MPR and can be observed without distortion. Therefore, the radius of the spherical surface is set appropriately in conjunction with the thickness of the observation object, whereby a precise diagnosis can be conducted.
