- process of evaluating the inside of a body using pictures and scans - seeks to reveal internal parts of the body under the skin - helps to diagnose and treat disease - part of biological imaging and also incorporates radiology such as X-ray - as of 2010 there have been 5 billion medical imaging studies conducted world wide - the equipment is manufactured by using technology from the semiconductor industry - there are different types of medical imaging such as radiography, ultrasound, nuclear medicine, magnetic resonance imaging and so many more - two forms of radiography, projection radiography and fluoroscopy - fluoroscopy produces real-time images of internal structures of the body -inserts barium, iodine, and air to help visualize internal organs as they function - projectional radiographs are more commonly known as X-rays - Magnetic resonance imaging is what an MRI scanner or a CT scan is. - Nuclear medicine encompasses both diagnostic imaging and treatment of disease - Ultrasounds uses high frequencies of broadband sound wakes in megahertz range that reflect off of the tissues to varying degrees to produce images - medical imaging is important when it comes to pregnancies - Shielding may be required when using medical imaging due to the main material used, lead. - shielding is only used typically in MRI's and magnetic shielding
