RADIATION-INDUCED THERMOACOUSTIC IMAGING

The acoustic wave generated by sudden thermal stress is used to obtain information non-invasively on the composition and structure of the stressed body. One or more acoustic transducers (1 and 1') are coupled with the surface of the body to intercept the acoustic wave and generate a corresponding electrical signal.

The radiation may be ionizing radiation, such as high energy electrons, photons (x-rays), neutrons, or other charged particles. The radiation may also be non-ionizing radiation, such as RF(2) and microwave electromagnetic radiation (3) and ultrasonic radiation (4). The electrical signal from the acoustic transducer (1) is amplified (5) and supplied to a digitizer (6), which provides a continuous stream of digital words corresponding to samples of the amplified signal. Because in most situations of practical interest the SJN ratio of a single ...

WIRELESS ULTRASOUND PROBE ASSET TRACKING

A wireless ultrasound probe has a probe case enclosing a transducer array, an acquisition circuit, a transceiver and a battery. The probe also includes a loudspeaker which produces audible sounds as a function of the range between the wireless probe and a host system.

This audible alert can be used to locate the probe by transmitting a paging signal which, upon reception by the probe, causes the probe to sound its alert. If the probe is moved to an unauthorized location where it is within range of a transmitter or receiver, the reception of a signal by the probe, the transmitter, or receiver will sound an alert signaling the unauthorized presence of the wireless probe.
