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.
4. Spacers. When weaving on a loom, the beads are locked in between the warp threads by the weft threads. The most common bead weaving technique requires two passes of the weft thread. First, an entire row of beads is strung on the weft thread. Then the beads are pressed in between the warp threads.
