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.
Let off motion: Causes unrolling of warp from the warp beam. Take up motion: Causes rolling of the cloth roller and cloth. â¸ Tertiary motions of loom : Warp stop motion, Weft stop motion, Warp protector motion,Weft mixing motion, Feeler motion, Break motion, Weft replenishment motion etc. [In Broadly] Primary motions of loom : Primary motion is necessary for weaving fabric. Without this mechanisms, it is practically impossible to produce a fabric.
