Minimum intensity projection

In scientific visualization, minimum intensity projection is a method for visualization of structures with low intensity in a specific volume. A two-dimensional image of a selected volume is generated where each pixel is represented by displaying the lowest attenuation value in each voxel.
MinIP is mainly used to diagnose lung diseases with computed tomography scans where the attenuation values are reduced. Another application is for assessing the bile tree and pancreatic duct which compared to the surrounding tissue is hypoattenuating.
