Loss Path Influence on the MRI Radio Frequency Pulse Sequence: A Theoretical Evidence

The RF pulse is initiated from either the loop or loopless MRI antenna. It has shown an increased advancement in recent times. Somehow, the concept has proven successful in the MR imaging procedure. Using the fundamental theories of the MRI concept, mathematical experimentation was carried out analytically to investigate the Loss Path Concept (LPC). The LPC was proposed to be one of the defects responsible for poor/blurred medical imaging of certain parts of the body. The LPC results obtain in this mathematical experimentation was found to be -56 dB and 6.7 dB. Theoretically, the LPC can be resolved mathematically by incorporating the molecular boundaries of the tissues. Practically, LPC can be resolved by introducing a detachable RF strip detector to synchronise-particles across different molecular boundaries and prevent patients from excess exposure to RF radiation.

Cumulative Single-Pulse NMR Echoes in Cobalt

<p class="1Body">In this work the cumulative single-pulse echo effect in cobalt was studied when a train of single-pulse echoes generated by a repeating single RF pulse sequence, exhibits growth rather than damping. The phenomenon is observed below some threshold value of radio-frequency pulse power when the nonresonant mechanism of single-pulse echo excitation in cobalt becomes effective.<strong></strong></p>
