Abstract: A visualization system including a first component (204) that processes volumetric image data indicative of a curved tubular tree structure having a plurality of branches so that the plurality of branches can be concurrently presented within a display window, wherein the volumetric image data is generated from x-ray projections acquired by a medical imaging system, and a second component (208) that concurrently presents the processed data to display the plurality of branches in a first display window and a region of interest identified on one of the branches in a second display window to present the region of interest in a spatial orientation different then that of the plurality of branches.

Abstract: In a virtual endoscopy method, an unfolding axis substantially along an elongated lumen is divided into axis segments. Ray casting directions are selected extending generally radially from the axis segments. At least some of the ray casting directions are tilted away from a camera position. Ray casting is performed along the tilted ray casting directions to define pixel values that are arranged into an unfolded view. The ray casting employs at least one of (i) volume rendering and (ii) computing a statistical characteristic of voxels over a preselected distance (dinterval) along the ray casting direction into the lumen-defining structure.

Abstract: In a virtual endoscopy method, an unfolding axis (100, 100?) substantially along an elongated lumen (150) is divided into axis segments (110). Ray casting directions (104) are selected extending generally radially from the axis segments. At least some of the ray casting directions are tilted away from a camera position (102). Ray casting is performed along the tilted ray casting directions to define pixel values that are arranged into an unfolded view. The ray casting employs at least one of (i) volume rendering and (ii) computing a statistical characteristic of voxels (238) over a preselected distance (dinterval) along the ray casting direction into the lumen-defining structure.
