Interactive Quantitative Measurement of Blood Vessel of Brain and Human Skeleton Visualization from Non-Enhanced MR Angiography and CT Data

Medical image analysis is more than just algorithms. Visualization of the original image data and processed results, interaction with the data, as well as the data themselves are also important. Medical image 3D visualization is one of the fundamental processes in medical diagnostics. Using the acquired 3D images it is possible to find the volume of pathology zone, which is the evidence of a specific disease. In this paper, we realized three-dimensional visualization of blood vessel of brain and skeleton from non-enhanced MR angiography and CT data. VC++ 2008 with VTK toolbox are used to reconstruct 3D images using the MR and CT slice sequence in DICOM format. The key algorithms, blood vessel of brain and human skeleton 3D visualization results are given. Furthermore, more complex interaction methods including mouse pick-up, angle and distance quantitative measure in space on 3D MR and CT images can be realized. The coordinates can be acquired by the mouse clicking in the 3D space, by which to realize the point mouse pick-up as well angle and distance interactive measure of the 3D medicine images. We can get quantitative information about 3D images through measurement. The methods can assist doctors to make better and more accurate diagnosis.
