Abstract:

BACKGROUND: Converting the two-dimensional (2D) tomographic image sequences into an intuitive three-dimensional (3D) image, exhibiting the 3D structure of human organs and morphology, and providing anatomical information which are not available by traditional methods, are basic tasks to achieve visualization of medical data.
OBJECTIVE: To establish a 3D visualization model based upon the intestinal slice data using 3D visualization technology for medical images for tracking the spatial position of a swallowable capsule robot within the intestinal tract, and for numerical simulation researching of intestinal ability to withstand water flushing of patients who suffered from fecal impaction or intestinal obstruction.
METHODS: General process of visualization for medical image slices includes image acquisition, registration, 3D surface-rendering reconstruction, and implementation of 3D digital visualization using the visualization toolkit (VTK) in visual C++.
RESULTS AND CONCLUSION: Using the VTK software, we implemented 3D digital visualization of colorectal image slices, including its rotation, zoom, pan of the 3D colorectal image, and integrated it into MFC graphical user interface. Actually achieved 3D visualization model could provide a reference image for researching on tracking the spatial position of a swallowable capsule robot within the intestinal tract, and for numerical simulation researching of intestinal ability to withstand water flushing of those patients who suffered from fecal impaction or intestinal obstruction.
