what the use of physics in medicine?

Question

(about one page please)

Answer 1

Physics is involved in all types of diagnostic imaging: xrays, MRI, CT scans, PET. Look them up and do your own homework.

Answer 2

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. Tomorrow's practice will include 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.

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.

Answer 3

Physics is employed when using any kind of human prosthesis for replacement of the physical component such as a leg or arm. Lever arms in the prosthesis have to match the bone and muscular structure of the original or damaged member. These measurements can be emulated into the prosthesis using calculations for kinematics, projectile motion, Newton's laws, work energy, impulse momentum, and rotational dynamics.

Answer 4

to learn drugs interior the united kingdom you like Chemistry A-point that's needed as maximum universities require it and you like an A grade in this project. different matters you are able to learn are Biology and Maths and Physics. you like a minimum of AAB at A-point and opposition is fierce with maximum scholars utilising having 6 or extra GCSE's at A grade. you will would desire to take a seat down the scientific faculties admission attempt UKCAT and/or BMAT (some uni's require the GAMSAT). you are able to desire to undertake an astounding sort of paintings adventure in a scientific institution or GP surgical treatment or some similiar healthcare placing. See here links for extra suggestions.

Answer 5

One that immediately comes to mind is the use of radioactive iodine to treat thyroid disorders. There are also a multitude of uses for radiation in the treatment of cancers. Liquid nitrogen is used to freeze basal cell skin cancers and warts. Cauterizing is a process that utilizes extreme heat to keep wounds from bleeding.
