Abstract
A system for providing high resolution imaging of objects having sub-millimeter dimensions comprised of at least one transmitter, at least one receiver, a coupling chamber, and a processor for recording attenuation and time of flight profiles of the transmitted signals. The signals are conditioned in a manner to provide high signal-to-noise ration (SNR) and minimal crosstalk and multipath effects at the receiver.
Claims30
A system for creating an image of an object comprising:
- a) at least one transmitter that transmits a signal;
- b) at least one receiver positioned to receive the signal;
- c) said at least one transmitter including a transducer that has at least two linear dimensions that are no greater than one millimeter;
- d) an area between said transmitter and said receiver for receiving the object in a position that causes at least portions of the signal to scatter before the signal is received by said receiver;
- e) a processor in communication with said receiver for extracting scattering information from the signal and for creating an image of the object based on the scattering information;
- and
- f) wherein said at least one transmitter and said at least one receiver are operable in transmission mode.
A system for creating an image of an object that has at least one linear dimension of less than one millimeter comprising:
- a) at least one transmitter that transmits a signal;
- b) at least one receiver positioned to receive the signal;
- c) an area between said transmitter and said receiver for receiving the object in a position that causes at least portions of the signal to be scattered before the signal is received by said receiver;
- d) a processor in communication with said receiver for creating a discernable image of the dimension of the object that is less than one millimeter;
- e) wherein the at least one transmitter has at least two linear dimensions that are no greater than one millimeter;
- and
- f) wherein the at least one transmitter and the at least one receiver are operable in transmission mode.
A method for creating an image of object positioned in an area between a transmitter and a receiver comprising:
- a) transmitting a signal from at least one transmitter;
- b) receiving a signal through at least one receiver;
- c) the at least one transmitter including a transducer that has at least two linear dimensions that are no greater than one millimeter;
- d) extracting scattering information from the received signal;
- e) creating an image of the object based on the scattering information;
- and
- f) wherein said at least one transmitter and said at least one receiver are operable in transmission mode.

- f) wherein said at least one transmitter and said at least one receiver are operable in transmission mode.
A system for creating an image of an object comprising:
- a) at least one transmitter that transmits a signal;
- b) at least one receiver positioned to receive the signal;
- c) an area between said transmitter and said receiver for receiving the object in a position that causes at least portions of the signal to be altered before the signal is received by said receiver;
- d) a processor in communication with said receiver for creating an image of the object;
- e) wherein said at least one transmitter includes a transducer having at least two linear dimensions that are no greater than one millimeter;
- and
- f) wherein said at least one transmitter and said at least one receiver are operable in transmission mode.
