摘要： The present invention concerns a method for the segmentation of vessel trees in 3D medical images, comprising steps of:
- defining an initial seed corresponding to a first identified point, said seed being a point of the 3D image corresponding to a vessel,
- performing region-growing segmentation by iteratively (i) identifying points in the neighborhood of previously identified points which belongs to vessels by using an identification criterion based on the application of a grey-level Hit-or-Miss Transform (HMT) with a set of structuring elements of a template size, and (ii) adding the identified points to the segmented vessel tree.
The region-growing segmentation is repeated iteratively for different template sizes.
The present invention concerns also a computer program implementing the method.

摘要： The present invention concerns a method for performing virtual endoscopy on a volumetric image of a lumen-defining structure having an elongated lumen, comprising steps of determining an unfolding axis substantially inside the lumen, defining sampling planes substantially perpendicular to and intersecting said unfolding axis at sampling positions, selecting ray casting directions in said sampling planes, performing ray casting to define pixel values, and arranging said pixel values into an unfolded view, wherein said ray casting directions are selected so that the angle increment between them is substantially inversely proportional to the ray propagation distance into the lumen, from the unfolding axis to the structure.
The present invention concerns also a computer program implementing the method.
