The Invention of Magnetic Resonance Scanner (MRI)

MRI uses the body’s natural magnetic properties to formulate an image of the soft tissues. It does this by using the hydrogen atom nucleus which has a single proton and is a spinning charged particle. The human body is made up of 70% water, which is hydrogen and oxygen. Those hydrogen nuclei (protons) spin inside the body, creating their own magnetic field. They are orientated randomly and cancel each other out when no field is applied.

Raymond Damadian is the man behind the MRI, he is the one who created it. His idea sparked from a machine called NMR, which is short for Nuclear Magnetic Resonance. An NMR “Scans salt loving bacteria called halophytes that contain twenty times greater potassium levels than most bacteria. Results were so promising that Damadian realized the technique could be used to diagnose cancer and other diseases in humans.” (Raymond Damadian, Inventor of the MRI). Raymond’s wife said that he struggled at times to create the machine, but he kept his faith, and kept working, and now the MRI provides answers to people who thought there never was one. Damadian was a strong Christian and gave all the glory to God.

“This MRI machine, or magnetic resonance imaging machine, is the most advanced and safest way to produce a magnetic image of the human body. Strong magnetic waves align the patients hydrogen atoms within the bodily tissues and cause them to vibrate and point in the same direction. Radio wave frequencies then disturb the hydrogen atoms so that they return to their natural randomized order. The imaging part of the machine then records and translates the data onto this screen here so that we are able to examine the patient’s brain, spine, soft tissues,and joints, which are the most common uses for an MRI (Sternlof). Why are we able to determine where the cancer or the tumor is by the image that is produced?” I asked. I was curious if anyone was slightly familiar with the information I had been talking about. A tall, brown haired man in the back of the

The MRI scanner is a large magnet that is 30,000 times stronger than the earth’s magnetic field. The force increases as a person or a ferromagnetic object move closer to the magnet. The strong magnetic field of the MR scanner is Always on even when the MR scanner is not in use.

As the world is becoming more technologically advanced, doctors and scientists are inventing new, harmless, and painless ways to observe your internal systems. In 1970, Raymond Damadian was able to connect the use of magnetism and radio waves as an instrument that could be of use in the medical field. He was able to create a tool that would change the medical world. This machine gives clear images of the inside of the body, making diagnoses easier to determine and also more accurate (Bergman).

Magnetic resonance imaging (MRI) is a test that lets your health care provider see detailed pictures of the inside of your body without using X-rays. Instead, strong magnets and radio waves work together in a magnetic field to form very detailed and sharp images. The images are viewed on a TV monitor in two- and three-dimensional form. The magnets and radio waves are harmless.

Magnetic Resonance Imaging is also known as MRI. This computerized device is used for scanning the

The first invention of radiology began with the creation of X-rays in 1895 when Wilhelm Roentgen, a 50-year-old professor of physics at Germany’s University of Wurzburg, made a discovery that would in a very short time change medical and human history. Though, discovered by accident, Roentgen’s discovery would help detect tumors, broken bones and bullets buried within bodies, never before seen with the naked eye. Since the invention of X-rays, there had been numerous discoveries of similar inventions, from image intensifier to ultrasound to magnetic resonance imaging. Without these inventions, humans would not have been able to see the inner workings of the body or detect key information in modern times that allow us to prevent serious illnesses where other inventions proved useless since imaging plays a huge role in diagnosis. In current society, radiology’s first creation has been exposed to most citizens, whether it is to detect a broken bone at the doctor’s or to determine a person’s risk of getting cavities at the dentist’s. Although, inventions from radiology does hold risks of radiation exposure amongst its patients, the benefits of them greatly outweighs its risks.

A MRI scanner mainly stands for magnetic resonance imaging. The MRI uses lots of magnetic fields and also helps scan with radio waves to create pictures of your inner tissues, organs and other body parts. The MRI scanner has strong magnetic fields that help a line all the particles that are called protons that are close to the hydrogen atoms. All of the protons that are inside the body line up against the magnetic field, because they react like little magnets.

A research article was put together after a cross-sectional study had been completed using an open MRI scanner. This study was specifically looking at people who have congenital heart disease. Researchers wanted to know how to get better quality images with each scanner as well as alter other effects that may impact image quality. While directing this study, people who were involved with the outcome and statistics noticed that obesity might have played a major role in this study. With the increase in overall patient body size, it is harder for patients to feel comfortable in exams that involve getting into a small area and staying still for a long period of time. Being in the enclosed bore of the MRI scanner for a long period of time can lead

A Magnetic Resonance Imaging (MRI) Technologist creates images, using computer-imaging systems, of the patient’s body to help the doctors diagnose and treat the patients’ illness and/or injuries. The MRI Technologist meets with the patients before the scan to explain medical procedures and answers questions they may have. They also collect medical information from the patient’s, family, and/or medical professionals and instruct the patient on what they need to do during the exam. Some MRI scan requires a medical substance for imaging which the MRI Technologist can administer. Once the image is taken, the MRI Technologist first processes the images, then checks the quality of the image and finally prepares summarized reports of the patient’s

According to (Morris and Liberman, 2005), MRI is principles technique which has a different physical from mammography and ultrasound. It indicates the protons water density in tissues including its magnetic interactions with molecules in its local surroundings. Magnetic interactions affect on MRI signal, that influences how fast the water protons can get back to equilibrium after receiving the radio-frequency energy from RF coil. MRI Parameters system can adapt to switch of T1 and T2 weighting that is providing image contrast to be formed.

NMR is a form of spectroscopy that utilizes external magnetic fields and signals to identify the chemical structure of organic molecules, creating a gradient image. Through applying an applied Radio Frequency, the proton is able to flip into higher energy states, and then relax. This process is recorded by a NMR Spectrometer, and the difference in energy provides it with a certain NMR Signal. The difference in the magnetic fields of the allows for a gradient image of the area. There are various types of imaging that are useful for fast imaging or 3D imaging such as Gradient-Echo Imaging or Volume Imaging. Some other applications of the same principles that apply to MRIs mainly relate to the identification of organic molecules such as Protein Folding and Drug Development. Although MRI is a relatively safe and harmless process as opposed to other forms of imaging such as X-rays, certain aspects still pose a risk to patients

Nuclear medicine is traced back to all sorts of sciences like physics, engineering, and chemistry. It is said that John Lawrence is the father of nuclear imaging because he was the first person ever to treat a leukemia patient with a radioisotope. From then on, a number of doctors experimented with patients with blood disorders and cancer by use of radioisotopes and were successful as well. One doctor’s procedure to halt the growth of cancer on the thyroid became the turning point in medical history. The beginnings of organ screening, for example PET scans, were born.

An MRI (magnetic resonance imaging) is a scan that uses a system of techniques, involving magnetism, radio waves and a computer to generate detailed images of the human body. Essentially, it is a tube encased by a large circular magnet. The patient would be placed on a moveable bed, which is then inserted into the tube. The magnet then creates a strong magnetic field that aligns the protons of hydrogen atoms. These hydrogen atoms come from the human body, which is 50-65% H2O. These atoms are exposed to a beam of radio waves. This spins the various protons of the body. As they spin, they produce a slight
