Ferromagnetic and superparamagnetic IONPs are currently used in biomedical industry as they shorten T1 spin lattice relaxation time and T2 spin-spin relaxation time. This results in brighter and sharp image. ... Visual detection cannot be done by magnetic nanoparticles: 5: Magnetic separation of biological sample is possible:

Reliable and consistent water/fat separation for an entire image and the success of the two-point Dixon technique are, therefore, affected by the presence of ϕ, which in turn is directly related to the magnetic field inhomogeneity (Eq. ). Nonetheless, it is interesting to note that by taking the absolute value of the images before summation or ...

Ore from the Jinzhulong Ta–Nb deposit was processed using a combination of gravity concentration and magnetic separation to upgrade the columbite–tantalite fines. Two flowsheets, namely for gravity concentration–magnetic separation (the conventional flowsheet) and magnetic separation–gravity concentration (the novel flowsheet), are …

Introduction. In recent years, T1 mapping—especially the T1 change before and after magnetic resonance (MR) contrast administration of the liver—has been used for the diagnosis of liver disease (1,2), assessing liver fibrosis (3-6) and inflammation (6,7), and for evaluating liver function (8-10).To quantify the T1 of the liver, previous studies often …

The estimate of T1 vs fat fraction and the SD due to model mismatch from a mono-exponential are plotted (Figure 4) for MOLLI and SASHA protocols for both out-of-phase (solid) and in-phase (dotted) mixtures of myocardium and fat.For a FF as low as 5%, the T1 is elevated by 60 ms for MOLLI and 80 ms for SASHA, and the T1 elevation is …

In fact, magnetic separation is the only feasible method for recovery of small magnetic particles (diameter ca 0.1 – 1 μm) in the presence of biological debris and other fouling material of similar size. Moreover, the power and efficiency of magnetic separation procedures is especially useful at large-scale operations.

Suspended Magnetic separators have proven to be the most effective for the removal of unwanted iron from heavy burdens of material being conveyed on fast moving belts. They are ideal for separation applications on wet or dry, fine or coarse materials in large or small tonnages. Safe, sure, tramp iron removal protects costly processing machinery ...
