Title:
RELIABLE SUBSURFACE SCATTERING METHOD FOR VOLUME RENDERING IN THREE-DIMENSIONAL ULTRASOUND IMAGE
Document Type and Number:
WIPO Patent Application WO/2021/187675
Kind Code:
A1
Abstract:
A reliable subsurface scattering method for volume rendering in a three-dimensional ultrasound image is disclosed. A subsurface scattering method for volume rendering, according to one embodiment, can comprise the steps of: generating a light-distribution template by using a diffused reflection property arising according to the density of an object that forms volume data in ultrasound image data; calculating the intensity of scattered light in the ultrasound image data through subsurface scattering by using the generated light-distribution template; and adjusting a light scattering region on the basis of the calculated light intensity by performing a coordinate transform step between different coordinate systems in order to visualize the ultrasound image data.
