What waves are used in hospitals?
Electric, magnetic and electromagnetic fields (EMF) with frequencies between 0 and 300 gigahertz can be used in hospitals for diagnostic or therapeutic purposes. The most important diagnostic application of EMF is magnetic resonance imaging (MRI), which uses static magnetic, low frequency and radiofrequency EMF.
How are gamma rays used in medicine?
Gamma rays are widely used in medicine and specifically in the area of oncology to treat malignant and cancerous tumors during a process called gamma knife surgery. In this type of treatment, concentrated beams of gamma rays are directed at tumors in order to kill cancerous cells.
Why is Ionising radiation used in medicine?
Diagnostic radiology, the imaging modalities using ionizing radiation, produces images of anatomical internal structures of human organs and physiological (functional) biological systems and helps significantly improve patient management and care in screening and diagnosis, assessing treatment response, predicting …
How is Ionising radiation used in medicine?
Ionising radiation is used in medicine in 3 ways: diagnostic radiology, which uses x-ray machines to obtain images of the inside of the patient’s body. nuclear medicine, which uses radioactive substances introduced into the patient for diagnosis or treatment.
How are sound waves used in medical work?
But when X-Rays hits objects like bones or organs such as your kidneys, the waves are blocked and a white image is created. And that’s how you get those black and white X-Ray images! There’s another type of wave used by medical experts, it’s called Ultrasound. This uses sound waves to look inside the body.
How are electromagnetic waves used in the medical field?
Some electromagnetic waves can be used in medicine for imaging purposes, which allows doctors to explore what is happening inside a person’s body without having to perform surgery. Infrared radiation is used in thermal imaging to produce a thermogram – an image of the body showing areas of different temperature.
How are shock waves used in the medical field?
Most of these devices claim to offer radio waves, electrical current, or magnetic fields. Shock waves were introduced almost 20 years ago to remove kidney stones. Shock waves have also been used in orthopedics.
How are ultrasound waves used to treat cancer?
A type of wave called Gamma rays can kill cancer cells. A machine called a ’gamma knife’ converges hundreds of gamma rays onto a tumour with remarkable accuracy. And as well as looking inside you, some ultrasound waves can help ease the pain of muscle injuries.
