Volume Rendering of Ultrasonic Sequential Images Based on Resampled Data

In this paper, we represent a method for volume rendering of ultrasonic sequential images which are resampled from normal ultrasonic devices. In order to get ideal slice image, the method use the up-sampling and histogram equalization as pre-processing, and then using the technical of volume rendering to reconstruct 3D of the slice images and observe the data from various angles. We implement the method based on VTK and accelerated by GPU, and successfully equipped the method to ordinary ultrasonic devices. The rendering results for the liver show that the method gives comparable effect to the images rendered by high-end ultrasonic devices, and the rendered images can be used for medical diagnosis.
