Lead Zirconate Titanate crystals are an important component of sonography. 

Electroencephalography, or EEG, can be defined as the measurement of electrical activity in different parts of the brain and its recording thereof as a visual trace.
Electrocardiography, or ECG, can be defined as a test that checks for problems in the electrical activity of the heart and records thereof. The crests and troughs in the line tracings that are done on paper are called waves.
Magnetoencephalography, or MEG, can be defined as a functional neuroimaging technique for mapping brain activity by recording the magnetic fields, produced by electric currents occurring as a natural process in the brain, using very sensitive magnetometers.
Sonography, also referred to as diagnostic sonography or utrasonography, can be defined as a diagnostic imaging technique based on the application of ultrasound. This procedure is used to check the internal body structures such as tendons, muscles, joints, vessels and internal organs of the human anatomy.
