is shown inFig. 6, where the meaning of bar graphs is the same as that shown inFig. 5.Table 4suggests that the proposed method can achieve the best performance for all the nine groups of MR images. In addition, the significance test of contrast measures shown inFig. 6indicates that our...

(e.g., CT and MRI) for which most vascular quantification methods have been developed, as these tend to image blood within the vessels, providing a single-peak intensity distribution across the vessel profile. Most existing quantification methods have been optimised for this single-peak ...
Louisa:Yeah. And, if you watch it in real-time on an MRI, it's crazy to see them getting pushed out of the skull. But, imagine your eye, the eye connects to the brain via this nerve called the optic nerve. It's one of the cranial nerves. It goes into the brain. And then, ...
In the future, our devices will be able to comprehend the meaning of bits and bytes of data streaming past, and use this knowledge to act on our behalf. To do so, computers must have the ability to think in terms of models—digital concepts of the people, places, and things fo...
Magnetic resonance imaging (MRI) of metabolic markers offers a powerful method to screen and diagnose diseases as well as to gauge response to treatment. Yet at Boltzmann equilibrium, spin polarizations of conventional MR (on the order of ˜10−5-10−6) are too low, and the metabolites...
83 They are considered an unlimited resource, meaning that electricity can be generated as long as the sun is shining, reducing dependence on finite fossil fuels and mitigating their negative impacts.84 Solar cells also produce no greenhouse gas emissions or air pollutants, making them safer and ...
In the present application, the terms “ESR field”, “RF field,” and “RF radiation” have the same meaning, and are used interchangeably. The magnetometer 100 operates by detecting the accumulated phase resulting from the relative energy shift induced by a magnetic field b between two Zeeman...
