Resonance

MRI stands for Magnetic Resonance Imaging. Dictionary.com defines it as a noninvasive diagnostic procedure employing an MR scanner to obtain detailed sectional images of the internal structure of the body. From my own prior knowledge, Magnetic Resonance Imaging is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the human body. The idea for Magnetic Resonance Imaging was initially conceived by Damadian in 1971 after he recognized…

increases the MR signal but because it displaces the deoxygenated hemoglobin that had been suppressing the MR signal intensity . The change in the MR signal, because of the neuronal activity is termed as Hemodynamic Response (HDR). Functional Magnetic Resonance Imaging (fMRI) is a technique used to visualize…

Three words, Magnetic Resonance Imaging. It’s the MRI, truly a miracle machine! The MRI has helped people in the past, is helping people in the present, and will help people in the future. Inside is high tech machinery that has both mechanically, and has chemically powerful equipment. The inventor is remarkably intelligent, as well as his invention. Both his religious and medical beliefs played a role in the creation. Question is, how did all this come to be? As a break though in the 20th…

Cardiac magnetic resonance imaging (MRI) is a noninvasive test that uses a combination of a large magnet, radiofrequencies and a computer to produce detailed images of a patient's heart as it is beating. An MRI is an effective tool for mapping the overall heart structure of patients and can use these images to search for aneurysms, tears , aorta bulging and damage caused by a heart attack, and other problems . It is derived from and based on the same basic principles as magnetic resonance…

the nanoscale range led to the development of the new age devices, Nanoelectromechanical systems (NEMS). These devices because of their size, they come with properties such as reduced mass, high quality factor (Q factor) and very high fundamental resonance frequencies. These qualities of NEMS makes them desirable for numerable applications such as components of signal processing devices, actuators and high speed sensors. NEMS can be used to construct resonators through a process of surface…

The anime, Terror in Resonance, indirectly points out the current Japanese government under Abe Shinzo as one of the source of neo-nationalism in Japan. Unlike many critical animes or shows, Terror in Resonance, addresses the name of the current Japanese government almost explicitly and even portrays the face of the current Japanese Prime Minister Abe Shinzo. In the anime, many governors in Japan is found out to have a lot of connections with the right wing nationalist organization, the Rising…

Magnetic Resonance Imagining (MRI) measure the frequency of magnetic-resonance signal. These signals can be measured at the same time, and their location is sorted based on resonant frequency. deCharms (2008) alikeness the MRI process to hearing several notes on a piano concurrently and then separating out the individual keys that produced each note based on the pitch of the note. MRI measures simultaneous signals emitted from an individual (just like the piano) and the origins of each signal…

Introduction: The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards.…

Nuclear Chemistry: The Magnetic Resonance Imaging The evolution of medicine is quite interesting. It first started out with spirits, omens, and other mythical beliefs. Then, the discovery of science has allowed for more practical ways to examine and heal a body. First the simple tools came into play, then the advanced technology. As the years keep progressing, more and more discoveries are being made. One example of this is magnetic resonance imaging (MRI). Nuclear chemistry has allowed for…

this, he struggled to gain acceptance from even his own mother due to his homosexuality. Fredrickson’s ideas of positivity resonance have the power to unite people through positive emotions and communication. In Selections from Love 2.0, by Barbara Fredrickson, positivity resonance is moment in which a positive emotion courses through two people’s brains…
