The following sections give a brief overview of these gradient-based applications. 1.8.1 Crusher Gradients to Dephase Transverse Magnetization "Crusher" gradients are used to dephase transverse magnetization and are widely used, for example, in localized in vivo
FID (S+) is destroyed by a crusher gradient (a gradient that dephases all signals but rephases only those that are generated by the correct pulses) on the slice-selection axis. It is heavily T2 weighted and has negligible T2 * weighting (,,, Fig 5c, ) (, 13 ).

· When rock is crushed, the product includes material of the size of the crusher setting, some slightly larger and the rest of the material smaller than the crusher setting. Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product.

A gravimentric gradient is the vector describing the flow of gravitons in a gravimetric field. In 2376, the USS Voyager was caught in a gravimetric gradient that pulled it toward Kelemane''s planet where it became trapped in orbit. (VOY: "Blink of an Eye")
In Final Cut Pro, select a title or generator, then open the inspector.Click the Gradient disclosure triangle to show the gradient editor. In the gradient editor, drag the small triangle between adjacent color tags or opacity tags to change the point where one tag''s effect
crusher gradients that target fast flowing spins [b-values below 20 s/mm2] as well as stronger, higher b-value gra-dients that target diffusing spins have been used), which remove signal from the vasculature based on the velocity of blood along the gradient
· DOSY/Diffusion using TopSpin 3.x Pg 5 This will setup the gradient array: i) Use ≥ 7 (where 11 to 25 are more typical values). ii) Run gradient amplitudes from 5 to 95%. iii) The squared (q) setup is recommended. III. Quick list of Processing Steps using
The roll crusher consists of a pair of horizontal cylindrical manganese steel spring rolls (Fig. 13.14), which rotate in opposite directions. The falling feed material is squeezed and crushed between the rollers. The final product passes through the discharge point
· Crusher gradients are applied at each side of the slice-selective gradient (applied during the 180 pulse) to achieve more accurate refocusing at time TE. So we apply a gradient in the negative direction that has an area equal to ½ of that of the readout gradient ( Fig. 14-5 ).
Crusher Gradients • Crusher Gradients: is a correction gradient that preserves the desired signal pathways while eliminating unwanted ones by manipulating the phase of the signals. • Consists of two lobes with the same polarity immediately before and after the …
Crusher area in mT/m*ms. Presat crusher is the presaturation crusher placed before the 180o tagging pulse, while postsat is the presaturation crusher placed after the 180o pulse. The imaging parameters for the phantom experiments were: TE=20ms, TI 0.5mm
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
A crusher gradient reversal method is proposed to overcome the stimulated echo artifacts in dual spin echo diffusion MRI. The polarity of crusher gradients before and after the two refocusing pulses is reversed according to the polarity of diffusion gradients. The ...

4 Oct 2016 The Gx is the phase encoding gradient, it is turned on during signal acquisition. TR also has an important effect on tissue contrast in the final image data. />which also includes crusher gradient and killer gradient pulse....
(2) The crusher gradient has a different effect for stimulation-onset than for stimulation-decline. In this case, the similarity between the local means depends on the time segment. Indeed, the results presented in Table 1 suggest that crushers are more effective during stimulation-onset and that local coherences are better preserved during stimulation-decline.

· The dimensions of the cans are also designed specially in order to withstand the outside pressures. A square inch of a soda can bears 80-90 pounds of force from outside. One atmosphere pressure force is equals to 720lbs or 3200newtons. So, in order to crush a soda can, you need to give nearly 50 pounds of force.

It should be noted that the crusher gradient causes narrowing in the slice profile. In practice, this effect can be compensated for by empirically reducing the slice-selection gradient amplitude. In Figure 3.11, we have assumed that all the magnetization is aligned along the + y axis after an excitation pulse and the refocusing pulse is also along the + y axis.
