The invention discloses a liver three-dimensional
database system constructed on the basis of a
DICOM (
Digital Imaging and Communications in
Medicine) medical image. The liver three-dimensional
database system comprises a data receiving module, an image reading module, a VTK (The
Visualization Toolkit) three-dimensional
image processing module and a liver information
database, wherein the data receiving module is used for obtaining a
liver CT (
Computed Tomography) image of a
DICOM format; the image reading module is used for converting the
liver CT image of the
DICOM format into the
liver CT image of a BMP (
Bitmap) format; the VTK three-dimensional
image processing module generates a liver three-dimensional image; and the liver information database carries out classification storage on a specific liver three-dimensional image according to specific liver source information. The VTK three-dimensional
image processing module comprises an image preprocessing submodule, a liver extraction submodule and an image drawing submodule, wherein the image preprocessing submodule reads the liver CT image of the BMP format and carries out image smoothness and
image enhancement processing on each liver CT image, the liver extraction submodule detects the contour edge of the liver and extracts a liver
contour line, and the image drawing submodule carries out
surface reconstruction on the liver according to the liver counter line to obtain a specific liver three-dimensional image.
