What PIEZOELECTRIC CRYSTALS means: Crystals in the transducer of an ultrasound device that vibrate when an electric signal is applied, emitting high-frequency sound pressure waves. The crystals are the crucial component of an ultrasound device both producing and detecting the ultrasound waves used to image structures inside of the body.

- Dictionary treating of patients at sites close to where they live. Rapid diagnostic tests are used to obtain immediate, on-site results. The success of the concept relies on portable, rapid diagnostic devices piezoelectric crystals definition.
- Definition Prosthetics:
- Dictionary The design, fabrication, and fitting of artificial body parts piezoelectric crystals explain.
- Definition Photon:
- Dictionary A particle of light or electromagnetic radiation. The energies of photons range from high-energy gamma rays and x-rays to low-energy radio waves piezoelectric crystals what is.
- Definition Positron Emission Tomography (PET):
- Dictionary radiopharmaceuticals to create 3 dimensional images. The decay of the radiotracers used with PET scans produce small particles called positrons. When positrons react with electrons in the body they piezoelectric crystals meaning.
