180-dgree linear interpolation (180 LI) - Type of algorith used for MSCT image reconstruction in which data acquired from a shorter distance (180 degrees) away from the reconstructed slice location are interpolated. absorbed dose - the amount of x-ray energy absorbed in a unit of mass. It is measured in grays.
