Volume rendering proved to be correct in all cases of disagreement, and sur-. This review illustrates potential limitations of each technique by directly comparing 3-D images of bone pathology created using volume rendering and surface rendering. comparison, volume rendering produced higher quality images compared with surface rendering. Tomandl, Peter Hastreiter, Christof Rezk. . Insights Imaging 7 , 849–856 (2016).


MATERIALS AND METHODS: Perspective views of helical CT and MR images were reconstructed from the data, and tissues were classified by.

Potential applications include anatomy teaching, patient education, surgical planning (cardiac, vascular, and trauma surgery procedures), disease detection.

New visualization algorithms permit the generation of almost photorealistic volume renderings of CT datasets.
Radiologists must interpret 3D images in association with cross-sectional images and with an understanding of volume-rendering parameters, techniques, and pitfalls.
J Comput Assist Tomogr 1997; 21:110-114.
Radiologists now have workstations that provide capabilities for evaluation of these data sets by using a range of software programs and processing tools.
In scientific visualization, a maximum intensity projection (MIP) is a method for 3D data that projects in the visualization plane the voxels with maximum intensity that fall in the way of parallel rays traced from the viewpoint to the plane of projection.
Minimum intensity projection (MinIP) is a data visualization method that enables detection of low-density structures in a given volume
May 1, 2006 · With an average of 400–1000 images in each volume data set, three-dimensional postprocessing is crucial to volume visualization
The diagnosis has always been almost exclusively radiological, due to the introduction of three-dimensional reconstruction techniques with Computed Tomography (3D-CT), including especially the Shaded Surface Display (SSD) and Volume Rendering (VR) algorithms

were identified in 2D-CT and in 3D-CT images by two radiologists twice each independently, and then performed by 3D-CT imaging using a computer graphics systems using bone and soft tissue protocols
Mar 10, 2005 · "So, as with any new technique in radiology, it is not sufficient to look at an image and assume that you know how to completely interpret it
