  • Patent number: 7574253
    Abstract: A method for processing signals, such as a tomography signal, in the time domain provides both high spatial resolution and high frequency resolution but at low cost. The method uses non-linear regression with a sinusoidal model to fit a sine wave to a portion of the signal that is less than a full cycle of a wave of the signal.

  • Patent number: 7289211
    Abstract: A method of visually quantifying a test material along with an imaging apparatus for practicing the method is disclosed. The method comprises: (a) illuminating the test material at a known angle of incidence with diffuse light of a known and adjustable polarization state; (b) receiving light from the test material with a polarization state modified by the test material; (c) measuring an intensity of the polarization components of the received light for each illuminated pixel substantially simultaneously; (d) calculating the Stokes Vector in two dimensions for each illuminated pixel; and (e) creating an image map for the known polarization state. The method may also include adjusting the known polarization or the incident angle of the diffuse light to create additional image maps. The method and apparatus are intended for use in medical imaging including minimally invasive surgery.

  • Patent number: 6736842
    Abstract: An expandable stent for use within a body lumen that is coated with a radiation-absorbing material and that is not plastically expandable at normal body temperatures but is expandable at a temperature between about 38° C. to 60° C. following exposure to radiation. The invention also relates to a method of deploying such a stent within the body.

  • Patent number: 6221068
    Abstract: Radiation is delivered to a wound in a series of sufficiently short pulses, with adequate cooling between individual pulses, to produce cumulative thermal denaturation and welding of the skin edges at the immediate area of the wound site, while avoiding unnecessary thermal damage to surrounding healthy tissue.
