Abstract Since the advent of magnetic resonance imaging applications in the health field forty years ago the technology has become a staple in hospitals all around the world. Magnetic resonance imaging commonly known to one of the safest forms of attaining pictures of the human anatomy. Although magnetic resonance technology is popular amongst health care providers for decades, until recently, scientists could not get the optimum image of some critical parts of the human anatomy. The magnetic resonance technology was limited in its imaging of the heart, lungs and skull. Early on the data the resonance provided could not be efficiently computed. To produce an image took up to five hours in the beginning of magnetic resonance imaging. Now…show more content…
He found that different kinds of animal tissue emit response signals that vary in length, and that cancerous tissue emits response signals that last much longer than tissue with cancer. In 1972 he filed his idea for using magnetic resonance imaging as a tool for medical diagnosis with the U.S. Patent Office. A patent was granted in 1974, this was the world 's first patent issued in the field of magnetic resonance imaging. In 1977 the first MRI exam was performed on a human being. It took 5 hours to produce one image Introduction to Magnetic Resonance Imaging (MRI) Magnetic resonance imaging (MRI) exams help physicians diagnose a range of conditions by producing images of internal organs and structures of the body. MRI is an imaging technique designed to visualize internal structures of the body using magnetic and electromagnetic fields which induce a resonance effect of hydrogen atoms. The electromagnetic emission created by these atoms is registered and processed by a dedicated computer to produce the images of the body structures. ( According to 2015 data provided by Radiological Society of North America (RSNA) there are 118 MRIs per 1000 inhabitants performed in the United States. That is about 38 million MRIs performed per year in the U.S. There is upwards to 100 billion dollars per year invested in radio frequency medical imaging in the US. MRI is popular for many reasons. Two of the main reasons for its popularity is safety and capability. MRI is safe
