Maximum Intensity Projection with fast rendering using Point Cloud Data Structure

Maximum intensity projection (MIP) is an important visualization method that has been widely used for the diagnosis of enhanced vessels or bones by rotating the MIP images. With The rapid spread of MDCT (Multi Detector-row Computed Tomography) scanners. This is a volume rendering technique which is used to extract high-intensity structures from volumetric data. MIP works on each pixel the highest data value rendezvous along the matching viewing ray is calculated. MIP is mostly used to extract vascular structures from medical MRI data sets. Example: angiography. Real-time processing and visualization of the 3D image data are the most important requirements in medical imaging. Among various existing 3D visualization methods maximum intensity projection (MIP) is a useful tool to visualize 3D images. However, much-time complexity is a drawback of using the MIP. The time complexity of the MIP depends on the number of data sets of the 3D data. To reduce time complexity, we developed a fast processing Shear-warp algorithm that produces better images in much less time
