Document Summary

Objectives: review basic post-processing functions and terms (from chapter 4, define and describe the process of advanced post processing, mprs, surface rendering, volume rendering, mip & minip (maximum and minimum intensity projections) Identify clinical application and significance of these technologies. Image manipulation: visualization tools, help us detect and measure the anatomy represented by our images, 2 categories, basic tools (chapter 4, advanced. Image magnification: make it bigger without any permanent changes to the data, coordinates for biopsies. Advanced tools: require, powerful computer workstations, advanced image processing capabilities. If using a 36 in chest region and a 32 in pelvis region= problems: consistent image center, no gaps, between the images being required. Limitations: must be isotropic voxels (x=y=z) for optimal quality, should have an overlap of at least 50% of slice thickness (if 3mm slice thickness, we should have 1. 5 mm spacing, what if we used thicker slices, retro recons.
