Multi-volume rendering is a technique that renders and displays multiple volumes simultaneously. In ultrasound imaging, multi-volume rendering is used for mixing 3D anatomical structures from B-mode imaging with blood flow information from power Doppler imaging (PDI) or color Doppler imaging (CDI). A variety of multi-volume rendering techniques have been proposed, such as post fusion (PF), composite fusion (CF) and progressive fusion (PGF). PF, which combines independently-rendered volumes, is unable to depict a spatial relationship between B-mode images (i.e., tissue structure) and PDI/CDI images (i.e., blood flow). The CF technique suffers from color distortion due to intermixing of hue values. In our recent study, the PGF technique was found to better retain and display tissue structures, vasculature and their depth relationship. However, the disadvantages of PGF include its high computational cost due to the requirement of maintaining a separate rendering pipeline for each volume (i.e., B-mode and power/color Doppler) and potential artifacts of depth-order ambiguity. In this paper, we present a new flexible computationally efficient multivolume rendering technique, named volume fusion (VF), and compare it with existing techniques. We have evaluated the VF method and other multi-volume rendering techniques with data acquired from a commercial ultrasound machine and found that the VF technique can preserve the spatial relationships well amongst multiple volumes without color distortion while the same rendering pipeline can be used to support both PDI and CDI volume fusion.
