Medical imaging
Diagnostic radiology, including x-rays, fluoroscopy, mammography, Dual energy X-ray absorptiometry, angiography and Computed tomography Ultrasound, including intravascular ultrasound Non-ionising radiation (Lasers, Ultraviolet etc.) Nuclear medicine, including SPECT and Positron emission tomography Magnetic resonance imaging, including Functional magnetic resonance imaging and other methods for functional neuroimaging of the brain. For case, nuclear magnetic resonance (often known as magnetic resonance imaging to avoid a most common concerns all about radiation), uses a phenomenon of nuclear resonance to image the physique. Magnetoencephalography Electrical impedance tomography Diffuse optical imaging Optical coherence tomography Terahertz radiation

Treatment of disease
Radiotherapy Sealed source radiotherapy Interventional radiology Non-ionising radiation Lasers, Ultraviolet etc. including photodynamic therapy and LASIK High intensity focussed ultrasound, including lithotripsy Nuclear medicine, including unsealed source radiotherapy Defibrillation
