3D volume construction from DICOM data
Systems and methods for constructing a 3D volume from digital imaging and communications in medicine (DICOM) data are provided. This 3D volume is part of a volume rendering pipeline. The 3D volume is accessible by volume rendering software for display on a 3D display device. A lookup table is used to adjust intensity values of voxels in the 3D volume.
