3D Post-processing
MPR – Multi-Planar Reconstruction
Real-time multi-planar reformatting of secondary views
• Viewing perspectives: sagittal; coronal; axial; oblique; double oblique; curved (freehand)
• Reconstruction along polygon and/or curved (freehand) cut lines
• Reconstruction based on reconstructed planes possible
• Reconstruction of user-defined ranges of parallel, radial or freehand cuts
• Selectable slice thickness and slice increment of reconstructed images
• Storing of post-processing protocols
• Annotations and 2D evaluations such as distance and ROI
MIP – Maximum Intensity Projection
3D reconstructions of vessels from a 3D data set, or a 2D sequential slice data set (acquired
with dedicated MR Angiography sequences)
• Volume of Interest (VoI) defined to increase reconstruction speed and to improve image
quality
• Freehand MIP
• Arbitrary views along any direction can be defined interactively with mouse-driven virtual
trackball
• Multiple view angles around any orthogonal axis
• Projections displayed as single images, as interactive movie or by fast paging
• MIP thin/MIP thick
MinIP – Minimum Intensity Projection
Similar to MIP but reconstructs the minimum intensity (e.g. for Dark Blood techniques)
SSD – Shaded Surface Display
Three-dimensional display of surfaces, such as vessels
• Selectable variable threshold values
• Multiple view angles around any orthogonal axis
• Rectangular and irregular Volumes of Interest (VoI) can be defined to improve image
quality
