“…The efficacy of DVR in comparison to Shaded Surface Display (SSD) for depiction of many anatomical districts [ 10 ] has been previously demonstrated. Indeed, DVR allows to display three-dimensional data sets of CT or Magnetic Resonance Imaging (MRI) [ 11 ] avoiding the limitations of previous techniques, as well as surface rendering, that needed semi-automatic intermediate conversion of the volume data [ 12 , 13 ] and reducing margin of error (p<0.001) in comparison to SSD and Maximum Intensity Projection (MIP) [ 14 , 15 ].…”

SummaryBackgroundSince cardiac anatomy continues to play an important role in the practice of medicine and in the development of medical devices, the study of the heart in three dimensions is particularly useful to understand its real structure, function and proper location in the body.Material/MethodsThis study demonstrates a fine use of direct volume rendering, processing the data set images obtained by Computed Tomography (CT) of the heart of 5 subjects with age range between 18 and 42 years (2 male, 3 female), with no history of any overt cardiac disease. The cardiac structure in CT images was first extracted from the thorax by marking manually the regions of interest on the computer, and then it was stacked to create new volumetric data.ResultsThe use of a specific algorithm allowed us to observe with a good perception of depth the heart and the skeleton of the thorax at the same time. Besides, in all examined subjects, it was possible to depict its structure and its position within the body and to study the integrity of papillary muscles, the fibrous tissue of cardiac valve and chordae tendineae and the course of coronary arteries.ConclusionsOur results demonstrated that one of the greatest advantages of algorithmic modifications of direct volume rendering parameters is that this method provides much necessary information in a single radiologic study. It implies a better accuracy in the study of the heart, being complementary to other diagnostic methods and facilitating the therapeutic plans.

Background: The purpose of this study was to conduct a morphological analysis of the temporomandibular joint, a highly specialized synovial joint that permits movement and function of the mandible. Materials and Methods:We have studied the temporomandibular joint anatomy, directly on the living, from 3D images obtained by medical imaging Computed Tomography and Nuclear Magnetic Resonance acquisition, and subsequent re-engineering techniques 3D Surface Rendering and Volume Rendering. Data were analysed with the goal of being able to isolate, identify and distinguish the anatomical structures of the joint, and get the largest possible number of information utilizing software for post-processing work.results: It was possible to reproduce anatomy of the skeletal structures, as well as through acquisitions of Magnetic Resonance Imaging; it was also possible to visualize the vascular, muscular, ligamentous and tendinous components of the articular complex, and also the capsule and the fibrous cartilaginous disc. We managed the Surface Rendering and Volume Rendering, not only to obtain three-dimensional images for colour and for resolution comparable to the usual anatomical preparations, but also a considerable number of anatomical, minuter details, zooming, rotating and cutting the same images with linking, graduating the colour, transparency and opacity from time to time.conclusion: These results are encouraging to stimulate further studies in other anatomical districts. DVR is a visualization technique that allows, for example, to display all the unknown information in three-dimensional data sets of CT [9],, and reducing margin of error (p < 001) in comparison to axial, shaded surface display ad maximum intensity projection [13,14].Previously, we tested direct volume rendering on various region of human body; these studies permitted to obtain high quality images that meliorated the knowledge of gross anatomy. In particular, we studied organs with homogeneous tissues, such as brain, succeeding to separate and visualize only white matter or only gray matter; furthermore, we studied knee and ankle joint visualizing ligament or muscle or bone, separately or contemporarily [15,16].Ishimaru et al., have described some methods for the application of volume rendering to temporomandibular joint study, using a[
