MPR - Multi Planar Reconstruction 2D reconstruction based on a volume, along a certain axis 2 1. Coronal 2. Sagittal 3. Paraxial 4. Irregular 3 1 4

MPR - Coronal & Sagittal Coronal (Abdomen) Sagittal (Abdomen)

MPR - Paraxial & Irregular Paraxial (Abdomen) Irregular (Abdomen)

MPR - Based on A Sagittal View The postprocessed MPR images can also be used as a reference image. This is an irregular cutline based on a sagittal view of the lumbar spine.

MPR - Based on A Sagittal View Paraxial cutline through a sagittal view to simulate gantry tilt with axial image quality

MPR - Based on A Coronal View Axial cutline through a coronal view of lumbar spine

SSD Threshold

SSD 2D SSD bilde 3D dataset

SSD - Shaded Surface Display SSD is a virtual 3-dimensional image. Thresholding determines which densities will be displayed. Grey values show the distance from the "screen" and give shadow effects Density information is lost 3D 2D

SSD with Different Thresholds 3D Face (threshold: -400 HU) 3D Head (threshold: 150 HU)

MIP The voxels with the highest value are selected voxel with the highest attenuation

MIP 2D MIP image 3D dataset

MIP - Maximum Intensity Projection The highest CT value in the viewing direction is presented in the 2D MIP images Density information is kept The bone structures which have higher intensities than the vessels make editing necessary You get a 3-dimensional effect when many MIP images around one axis are displayed in Cine mode

3D Edit Eliminate what you don’t want... Just see what you want to see... Normal Axial Image Edited Image

VRT - Volume Rendering Technique Mean value

VRT 2D VRT image 3D dataset

Color and transparent 3D display VRT - Volume Rendering Technique Color and transparent 3D display Percentage HU Tissue 1 Tissue 2 Separate tissues via HU into different Brightness/Opacity/Color Overlay display of different organs

SSD & MIP SSD - no density difference MIP - density difference kept

MIP & MPR MIP - max. intensity kept , & 3 Dimensional MPR - all intensities kept , & 2 Dimensional
