Abstract:
Objective Turn the CT sectional image into three-dimensional imaging based on VTK, in or-der to make better treatment programs for patients with liver cancer. Methods Establish visualization toolkit (VTK) visualization development environment based on VC6.0, obtain patient's CT images in DICOM format, use VTK filter and Laplacian sharpening template for pre-treatment of the images, and then use Ray-Casting algo-rithm for three-dimensional reconstruction. Results We can get three-dimensional images with higher resolu-tion and faster imaging speed through this method, which can also be cut, rotated and zoomed. Conclusion Ray-Casting algorithm based on VTK can be used for the three-dimensional imaging of human liver. With the as-sistance of three-dimensional images, doctors can detect the location of diseased tissue more easily and observe the shapes of diseased tissue intuitively.
