Magnetic ink is very useful because it is readable both by humans and by specialized equipment. It is one of the components that makes it possible to process personal checks securely‚ quickly and accurately. Magnetic ink character recognition (MICR) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents. The MICR encoding‚ called the MICR line‚ is at the bottom of cheques and other vouchers and typically includes

Magnetic resonance imaging (MRI) is a type of scan that produces detailed images of the inside of the body using radio waves and strong magnetic fields without using radiation. An MRI scanner is a large tube that contains powerful magnets. During the scan‚ you lie inside the tube. Almost any part of the body can be examined using an MRI‚ including the brain and spinal cord‚ bones and joints‚ heart and blood vessels‚ internal organs‚ and breasts. MRI scans are safe and painless. Almost everyone

MAGNETIC RESONANCE IMAGING Magnetic resonance imaging (MRI) has developed into one of the most versatile techniques in clinical imaging and biomedical research by providing non-invasively high resolution‚ three-dimensional anatomical and contrast-enhanced images of living tissue. The two most common groups of contrast-enhancing agents are gadolinium-based complexes and magnetic nanoparticles. Both types of contrast agents shorten locally the relaxation time of bulk water protons via rapid exchange

Magnetic resonance imaging (MRI) is a type of scanner that uses strong magnetic field and radio waves to produce complete images inside the body. An MRI scanner is a large tube that contains strong magnets. The patient lie inside the tube during the scan. The MRI scanner is used to observe almost any part of the body including the brain and spinal cord‚ bones and joints‚ breasts‚ heart and blood vessels and internal organs such as the liver‚ womb or prostate gland. The results of an MRI scan can

INTRODUCTION: Magnetic Resonance Imaging(MRI) is a non invasive medical imaging method widely used in hospitals and in research. In year 1946 Felix Bloch of Standard /university and Edward Purcell of Harvard University made the first succesful nuclear magnetic resonance experiment to study chemical compounds‚ they were awarded the Nobel Prize for physics in 1952. In early 1980 ’s the first human magnetic resonance imaging( MRI) scanners became available‚ producing images of the inside of the

Chapter 4‚ page 1 4 Nuclear Magnetic Resonance Pieter Zeeman observed in 1896 the splitting of optical spectral lines in the field of an electromagnet. Since then‚ the splitting of energy levels proportional to an external magnetic field has been called the "Zeeman effect". The "Zeeman resonance effect" causes magnetic resonances which are classified under radio frequency spectroscopy (rf spectroscopy). In these resonances‚ the transitions between two branches of a single energy level

History and Science Behind MRI: Open or Closed Case? Magnetic Resonance Imaging (MRI) has been called one of the most comprehensive and efficacious diagnostic imaging modalities in medical history. It became a viable clinical technique in 1982 and during its relatively short lifetime has become the primary imaging modality for investigations of the brain‚ spinal cord‚ spine‚ cancellous bone‚ and joints. It is widely used for the identification and staging of tumors‚ investigations of large

Lab #11 Faraday’s Law of induction Purpose: To prove Faraday’s Law of Induction using an oscillating wand which swings through a magnetic field. In addition‚ we studied the conversion of mechanical energy to electrical energy. Questions: 1. What are the possible errors in this experiment? There are a variety of sources of error which may have affected the results of this experiment. There could have been an error in the setup of the Rotary Motion setup or its setup within the Logger Pro program

The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets‚ it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type‚ middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. 1‚ to maintain good lubrication condition is to extend the
