Looking Within: How X-Ray, CT, MRI, Ultrasound, and Other Medical Images Are Created, and How They Help Physicians Save Lives
Looking Within: How X-Ray, CT, MRI, Ultrasound, and Other Medical Images Are Created, and How They Help Physicians Save Lives
A hundred years ago, a doctor had no way to look within the body of a patient other than to slice it open. That changed radically at the turn of the century, with the discovery of X-rays. X-ray and other forms of diagnostic imaging technology developed slowly but steadily from then until the 1970s, at which point a revolution occurred. Made possible largely by the availability of powerful but inexpensive computers, the rapid and widespread adoption of computed tomography (CT) and, a decade later, of magnetic resonance imaging (MRI) greatly expanded the power of clinical imaging, and even changed the ways in which physicians view and think about the human body.This unique guide explains how the principal imaging devices work and how they help physicians save lives. It gives readers a grasp of the major medical technologies that might come to play important roles in their lives, and it provides succinct, easy-to-understand, and reliable explanations for those who wish to explore the issues of the associated benefits, costs, and risks in an informed manner. In nonspecialized language, Looking Within discusses how X-ray, fluoroscopic, CT, MRI, positron emission tomography (PET), ultrasound, and other medical pictures are created, and explores the essential roles they play in the diagnosis and treatment of patients. It should be of interest to patients and their friends and loved ones, and to those who are simply curious about this vitally important, exciting, and cutting-edge branch of medicine. Its brief but clear descriptions of how these essential tools work should also be of value to health care providers in supporting and educating their patients.

Since ancient times, mankind has studied the benefits of electrotherapy. They used animals as sources of electric current that could be placed on painful areas to promote healing. Live electric fish were used to numb painful areas of the body until the 18th century. During the late 18th century, Luigi Galvani, an Italian physician, physicist and philosopher, came up with Galvanism which involves the use of direct current in medical procedures. In the early 19th century, Michael Faraday, an English scientist, came up with Faradism - the use of interrupted and alternating current in the form of electroacupuncture, transcutaneous electrical stimulation (TENS), and dorsal column stimulation. Three popular theories explain how Electrotherapy works: The electrical impulses block the pain signals from the hurting part of the body, and trick the brain into thinking that there is no pain. The electrical stimulation releases endorphins, which is the body's natural pain killer. The electrotherapy improves blood circulation that promotes healing of the affected areas. Currently, there are several electrotherapy machines available. The more popular ones are TENS units, interferential stimulation (IF) units, and electrical muscle stimulation (EMS) units. All of these machines use electrode pads that transfer the electric current from the source unit to the skin and muscles. Electrotherapy is primarily done for managing pain from the following sources: Osteoarthritis Fibromyalgia Low back pain Neck pain Bursitis Tendinitis Labor pains Other painful medical conditions For electrotherapy to be effective, one must use quality electrodes pads that provide excellent conductivity. Our USA made Tyco pre-gelled reusable electrode pads evenly distribute the current on the affected areas, thereby providing relief that is like no other. With our Ultimate TENS Unit Pads as your electrodes of choice, you can now LIVE LIFE PAIN FREE!
