What is tangent law in magnetism? Why do you use a coil in a magnetic field? What is meant by the term Moment of Inertia? What is the moment of inertia of the system? Give a symbolic answer. What is shielding and deshielding in NMR (Nuclear Magnetic Resonance)? Give an example. ...
For instance, the intrinsic intensity of ESR is much higher than that of NMR. However, this advantage is usually counterbal- anced by the reduction in the output power of conventional light sources such as Gunn oscillators or backward-traveling wave oscillators (BWO) with increasing frequency. ...
functional, molecular medicine and hybrid imaging, that is understood as the hardware-based combination of complementary anatomical and molecular imaging. These include novel detector technologies for ionizing radiation used in CT and nuclear medicine imaging,...
In the magnet technology, the superconducting magnet, active shielding, and “zero helium boil-off” are a few significant milestones that have helped shift MRI from being low field (0.1 – 0.2 T) in the early days to the present day of high-field systems (1.5 – 3.0 T) as the standard...
