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.
For example, here is how the woven label is made: The looms weave polyester yarns, recreating the logo submitted by the client in the form of artwork. The loom works with two threads, the warp and the weft. The threads are interlaced lengthwise (warp) and widthwise (weft). The modern computerised Jacquard loom provides a ribbon which is then cut by a hot knife to the desired dimensions. This cutting technique seals the label to prevent fraying.
