VIRTUAL ENDOSCOPE METHOD USING THREE-DIMENSIONAL IMAGE PROCESSING TECHNIQUE

摘要

PURPOSE: A virtual endoscope method using a three-dimensional image processing technique is provided to improve the quality of image by using the image reconstruction method and the virtual reality method. CONSTITUTION: A cross-sectional image is read(S110), wherein the cross-sectional image is outputted from an apparatus, such as an MRI(Magnetic Resonance Imaging), a CT(Computed Tomography), and an ultrasound imaging, for generating the cross-sectional image. A three-dimensional volume data is generated based on the cross-sectional image(S130). After the three-dimensional volume data is classified, a hierarchial tree-structure is created by using spacially related volume data to divide a space(S140). In the divided space, a portion representing a current view point is rendered(S160).
