Magnetic Resonance Imaging Abstract Magnetic Resonance Imaging has emerged as an important medical diagnostics tool in the last 20 years. The procedure consists of exposing the human body to a short duration pulse of very strong magnetic field. Under the influence of this magnetic field, Hydrogen protons in the water and fat molecules in the human body which are randomly aligned orient themselves in the direction of the magnetic field and spin on their axes…

Extract of sample

The very large cost of MRI machines and their large size and specialized installation requirements acts as a deterrent to wider use of this technology. There is work underway that promises reduced costs and size of MRI machines, especially in the form of specialized machines for the scan of extremities such as wrists and ankles. The success of this effort could lead to wider use of the technology. Keywords: Magnetic Resonance Imaging, diagnostics, magnetic pulse 1. Introduction: The first Magnetic Resonance Image (MRI) was produced in 1973 and the procedure has now become a rapidly growing medical diagnostic tool for the medical profession. Over 30 million MRI procedures were done in the US in 2010 and new advances in technology is making specialized MRI procedures available for screening for a wider range of diseases and medical conditions each year. The human body can be considered to be essentially made up of three types of material; bone which is hard and made up of minerals such as calcium, soft tissue including muscles, flesh, blood vessels and organs such as liver, kidney, heart and lungs and fluids including blood and air. ...

Advantages of miniaturization Miniaturization is very vital as it has several advantages. It requires low cost, has the ability to accommodate greater density and it is high in speed. The small electronics are very faster as the signals they transmit travel over short distances and the devices do not travel for long distances within the implemented device. Furthermore, packing of small sized…

the use of the x ray machine in the medical field. And how it was invented and how far it has come (technology wise) and also it
The discovery was actually accidental. The scientist found that invisible rays were emitted from a cathode ray tube and that these could penetrate wood and also paper. These rays were able to create a glow on a screen that was several years yards away. The glow was fluorescent. The screen that was observed was barium platinocyanide screen (Assmus, 10). The tube generating X-rays, the cathode rays…

For example, when Bell telephone laboratories announced to the world the invention of the transistor in 1948, the press of the day announced that more than hundred could be held in the palm of the hand (Hayes, 2011). Today with the current technologies more than a 100 billion of these can be held at the palm of the hand. What is more interesting was that the transistors even cost less than dollar…
