  • Radiation director apparatus and method using piezoelectric movement
    Patent number: 6676020
    Abstract: A radiation director is coupled to move under the control of a piezoelectric element. The director directs electromagnetic radiation from a radiation source under the control of the piezoelectric element. In a scanning station embodiment, an electrical signal source is connected to cause the piezoelectric element to vibrate, and a radiation detector is positioned to detect radiation from an object scanned by the radiation. In a radiation scanning method, a piezoelectric element is caused to move in a reciprocating fashion, and the movement of the piezoelectric element is used to direct an electromagnetic radiation beam in a scanning motion.
