         Positron emission tomography (PET) is a type of nuclear medicine procedure that measure metabolic activity of the cells of body tissues. PET is actually a combination of nuclear medicine and biochemical analysis. Used mostly in patients with brain or heart conditions and cancer, PET helps to visualize the biochemical changes taking place in the body, such as the metabolism (the process by which cells change food into energy after food is digested and absorbed into the blood) of the heart muscle.       Since PET is a type of nuclear medicine procedure, this means that a tiny amount of a radioactive substance, called a radiopharmaceutical (radionuclide or radioactive tracer) is used during the procedure to assist in the examination of the tissue under study. Specifically, PET studies evaluate the metabolism of a particular organ or tissue, so that information about the physiology (functionality) and anatomy (structure) of the organ or tissue is evaluated, as well as its biochemi

The new technologies could impact every aspect of our medical lives from the way our bodies are analyzed for medical issues to the way major surgeries such as organ transplants are conducted.          The field of biomedical engineering is exploiting with ideas and young professionals eager to implement them in a real world setting. In fact, the field of biomedical engineering is one of the fastest growing fields out there. With all of

 Scope of Bio-Medical Engineering       Straddling the life sciences, the physical sciences and engineering, Nature Biomedical Engineering covers materials, therapies, devices, technology, systems, methods and processes that facilitate the understanding of human disease, or its prevention, diagnosis, treatment, alleviation or monitoring.     The journal disseminates biological, medical and engineering advances-of fundamental, mechanistic, methodological, technological, therapeutic, translational or clinical that can directly lead to or inspire improvements in human health or healthcare. The emphasis is on advances that draw on both the biomedical sciences and the physical sciences, engineering, mathematics or informatics.    The scope hence excludes advances that improve the understanding of human biology or disease but whose relevance for health or healthcare is judged to be insufficient, as well as advances that do not make use of principles or tools from the physical sciences or en

ELECTROENCEPHALOGRAH (EEG)    Electroencephalogramh is an instrument for recording the electrical activity of BRAIN, by suitably placing surface electrodes on the scalp. EEG, describing the general function of the brain activity, is the superimposed wave of neuron potential operating in a non- synchronized manner in the physical sense. It's stochastic major originates just from this, and the prominent signal groups can be empirically connected to diagnostic conclusion .       Monitoring the electroencephalograh has proven to be an effective method of diagnosing many neurological illness and diseases, such as epilepsy, tumor, cerebrovascular lesions, and the problems associated with trauma. It is also effectively used in the operating room to faciliate anaesthetics and to established the integrity of the anaesthetic patient's nervous system. This has become possible but then advent of small, computer-based EEG analysers. consequently, routine EEG monitoring in the operating room

  Artificial limb (c. 550 B.C.E)         The earliest written reference to an artificial limb occurs in an epic Indian poem"Rig-Veda", which was compiled between 35000 and 1800 B.C.E written in Sanskrit the poem includes a description of the amputation of the warrior Queen vishpla's leg during battle. Later fitted with an iron prosthesis by the Ashvins (celestial physicians),she returned to combat.        Most authorities doubt the story of Queen Vishpla, and turn to the Histories of Herodotus for the first plausible reference to a prosthetic limb. Herodotus describes how, in the mid sixth century B.C.E.,Hegesistratus of Eli's, a Persian soldier and seer imprisoned by the Spartans, was sentenced to death, and cut off part of his foot to escape from the stocks. Hegesistratus fashioned a wooden prosthesis to help walk the 30 miles (48 km) to Tregea, but unfortunately was captured by Zaccynthius and beheaded.                   In the first century B.C.E., Pliny the elder

ARTIFICIAL  HEART(1963)                   The artificial heart is a machine that pumps blood around the body and is designed to replace the natural heart when it no longer works efficiently due to conditions such as heart failure. paul winchell (1922-2005), a U.S. television ventriloquist, was the unlikely inventor of the artificial heart.                    At a cast party, wicnhell met surgery Dr. Henry Heimlich, inventor of the Heimlich maneuver for choking. After observing Heimlich in his operating room, Winchell thought that an artificial heart could keep blood pumping in during difficult open-heart procedures. with Heimlich advice, Winchell designed an artificial heart and built the first prototype. He filed for a patent in 1956, which he received in 1963.                                                       Winchell donated the rights to his design to the University of Utah, allowing Robert Jarvik and others to build an artificial heart, dubbed the Jarvik-7. Jarvik introduced

    ELECTROCARDIOGRAM       An electrocardiogram  records the electrical signals in the heart .  It's a common and painless test used to quickly detect heart problems and monitor the heart's health.      Electrical signals from the heart characteristically precede the normal mechanical function and monitoring of these signals has great clinical significance.     ECG provides valuable information about wide range of cardiac disorders such as the presence of an inactive part(infarction) or an enlargement (cardiac hypertrophy) of the heart muscle.
