Susceptibility weighted imaging (SWI), is a new type of contrast in MRI different from spin density, T 1, or T 2 imaging. This method exploits the susceptibility differences between tissues and uses a fully velocity compensated, three dimensional, RF spoiled, high-resolution, 3D gradient echo scan.
Motions of Loom | Weaving Loom Motion | Primary Motions of Loom | Secondary Motions of Loom | Tertiary Motions of Loom. 1. Primary Motions: These are fundamental or essential mechanisms. Without these mechanisms, it is practically impossible to produce a fabric. It is for this reason that these mechanisms are called âprimaryâ mechanisms.
Pseudopodial Locomotion: It is of the slow, creeping type of motion. Pseudopodia play an important role in it. They are further divided into lobopodia, filopodia, axopodia and reticulopodia. Filopodia are thread like structures made up of ectoplasm. Lobopodia are broad with blunt ends.
