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.
A woman in Konya, Turkey, works at a vertical loom. A loom is a device used to weave cloth and tapestry. The basic purpose of any loom is to hold the warp threads under tension to facilitate the interweaving of the weft threads. The precise shape of the loom and its mechanics may vary, but the basic function is the same.
