Liver three-dimensional database system constructed on the basis of DICOM (Digital Imaging and Communications in Medicine) medical image

Abstract

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.

Description

technical field [0001] The invention relates to a medical image processing system, in particular to a medical image three-dimensional visualization system. Background technique [0002] VTK (The Visualization Toolkit) is an open-source visualization development kit from Kitware Corporation of the United States. Mainly used for computer 3D graphics visualization. It has powerful functions in scientific visualization, especially in 3D reconstruction such as surface rendering and volume rendering, which makes it widely used in the field of 3D reconstruction of medical images. At present, some commercial 3D reconstruction systems of medical images are used for reference or directly. VTK. VTK supports Window, Unix and other platforms, and supports programming languages ​​such as C, C++, Java, Tcl / Tk and Python. VTK uses the 3D graphics library OpenGL at the bottom layer, and uses the object-oriented method to design. It shields the details that we often encounter in the visual...

Problems solved by technology

However, the liver segmentation method based on CT images has many procedures and time-consuming procedures for reconstructing liver 3D CT stereoscopic images, and is not suitable for processing a large number of liver images at one time.
