Abstract

This article carries on a new method which can improve quality and speed of 3D visualization. This method, first based on dynamic threshold method, divides region of interest ROI from the original image; then extends bounding box algorithm to 3D space, and combines it with ray casting algorithm. We validate the validity and robustness of this method in 3D reconstruction, experimenting with 3D lung parenchyma´s image, vascular image and bones´ image, which used to be 2D medical images about chest CT.
