Therefore, maximum b-values, also greater than 800 sec/mm in Yamada's opinion, are necessary in order to reduce intravoxel incoherent motion effects [ 37].
Dense sampling in k-space center region such as Gaussian-weighting or inclusion of k-space center 1 line was better for CS, due to the fact that most energy is located in the k-space center region and also due to incoherent aliasing effects from variable-density sampling [ 13, 16].
We investigate the incoherent pumping field effect on the system.
In fact, this system can be used as an optical switch, in which the propagation of a laser pulse can be controlled with tunnelling effect, incoherent pumping field and terahertz signsl.
For a voxel with a large vascular fraction, the MRI data decay can deviate from a monoexponential form, in particular showing a fast decay in the range of low b values generated by the intravoxel incoherent motion (IVIM) effect [ 27, 28].
It is important to say that the smaller the maximum b-value used, the greater the ADC values: that is caused by the contribution of intravoxel incoherent motion (IVIM) effects (e.g., capillary perfusion and flow phenomena), which are more than diffusion.
The show's sequence of events may sound incoherent, yet the overall effect is mesmerizing, sometimes funny, even beautiful.
Ambiguous anaphors elicited a sustained negative shift (Nref effect), and incoherent anaphors elicited an N400 effect.
Here, by taking into account the incoherent pumping field, tunnelling effect and terahertz signal, the probe gain is appeared around λ = 1.55μm in the spectrum.
