New Phenomena

As I mentioned in my previous article, physics creates changes, it starts everything, and leads to a new phenomena. One of these phenomena is the creation and invention of machines used in the world of medicine. X-rays, PET, CT, MRI, IMRT and gamma-knife, radiation therapy, arthroscopy, ultrasound, and laser surgery are well known techniques employed in today's medical practice. We even use in today’s practice nanotechnologies, intravascular robotics, cryoablation, laser scalpel, computer diagnostics, and molecular medicine. Perhaps not surprisingly, all originate from physics! Physics and its discoveries have been at the forefront of medical diagnosis and treatment since the discovery of X-rays in 1895 as stated in www. google.com, citing the discovery of x-ray. This close fit is a natural consequence of the wide-ranging implications of the discoveries of physics, the fundamental science. With medical practice and biology becoming more quantitative as our understanding of life's molecular processes grows, the myriad experimental and theoretical techniques of physics will be increasingly prominent on the leading edge of medicine and health care. In today's world, careers in medicine and health care abound, covering a wide range of possibilities from clinical practice as a physician to clinical research as an MD/PhD scientist and non-clinical investigations as a PhD researcher, as well as numerous professions especially us NURSES, in support of medicine.
Physics is very important in the field of nursing as well as medicine, some importance of Physics are as follows: Health Physics is concerned with radiation safety, Medical Physics is concerned with the application of the concepts and methods of physics to help diagnose and treat human disease Radiological Physics, concerned with the use of radiation for therapy and diagnosis Biological Physics, concerned with the application of the concepts and methods of physics to the solution of biological problems and the understanding of biological processes. Whether through research, medical support, or medical practice, physics serves important roles in all aspects of the great humanitarian effort for health care.
