maximum intensity projection
Also written as: MIP — Maximum Intensity Projection
Post-processing technique that displays the brightest pixels along viewing rays to create angiographic images.
Full Definition
Maximum intensity projection (MIP) is a three-dimensional rendering technique commonly used in vascular imaging to create angiographic-like images from cross-sectional data. The algorithm selects the highest intensity voxel along each ray projected through the volume dataset, effectively highlighting contrast-enhanced blood vessels while suppressing background structures. MIP images can be generated from CT angiography or MR angiography datasets and are particularly useful for displaying vascular anatomy in a format familiar to clinicians. However, MIP images may obscure overlapping structures and lose depth information, making them complementary to rather than replacements for source images and multiplanar reconstructions.
Usage
Usage note: Distinguish from MinIP (minimum intensity projection) used for different clinical applications.
