We begin with a brief review of the major structural and functional neuroimaging. research methods that are commonly in use, including computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography (PET), functional. magnetic resonance imaging (fMRI), and diffusion-weighted magnetic resonance.
Ultrasonic And Sonic Instruments are used for removing plaque, stains and calculus. There are 2 types of ultrasonic units : a) Magnetostrictive : Vibrations of the tip are elliptical hence all the sides can be used. b) Piezo-electric: Pattern of vibration of the tip is linear : only 2 sides of the tip are active.
