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.
- Definition Progenitor Cells:
- Dictionary Progenitor cells are cells that are similar to stem cells but instead of the ability to become any type of cell, they are already predisposed to develop into a particular type of cell piezoelectric crystals definition.
- Definition Point-Of-Care:
- 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 explain.
- Definition Polymer:
- Dictionary composed of many repeating subunits. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA. Polymers have unique physical properties, including 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.
