    2. Simultaneous imaging, monitoring, and therapy

      Simultaneous imaging, monitoring, and therapy
      Using the disclosed intravascular devices it is possible to image tissues, deliver therapy, and evaluate the tissue after the therapy is delivered. One embodiment is a catheter configured to provide ultrasound imaging, drug delivery, and Doppler flow analysis. The devices can use ultrasound imaging as well as optical coherence tomography (OCT).

    3. Guarded imaging devices and methods

      Guarded imaging devices and methods
      An integrated therapeutic and imaging device that uses at least two balloons to provide a guarded zone that can be evacuated and replaced with a fluid that is sufficiently clear to permit optical coherence tomography (or even high resolution ultrasound) imaging that would otherwise be of poor quality or impossible. Methods of making and operating the imaging device to obtain clear, high quality images, as well as treating a patient ...

    4. Polarization sensitive optical coherence tomography system

      Polarization sensitive optical coherence tomography system
      The invention generally relates to a polarization sensitive optical coherence tomography (OCT) system that includes both polarization maintaining and single mode optical fiber and methods of use thereof. Generally, OCT systems of the invention have a light source and a differential path interferometer that includes a sample arm and a reference arm. A splitter is used to split light from the light source to the sample arm and the reference ...

    5. Optical-electrical rotary joint and methods of use

      Optical-electrical rotary joint and methods of use
      The present invention relates generally to rotatable optical couplings, and more particularly to a manually separable and re-connectable optical-electrical rotary joint. The invention provides a manually separable optical-electrical rotary joint in which an optical signal and electrical signal are transmitted while a downstream component rotates relative to an upstream component, for example, as driven by a motor at the upstream component. Further, the downstream component can be easily manually unplugged ...

    6. Automatic stent detection

      Automatic stent detection
      This invention relates generally to the detection of objects, such as stents, within intraluminal images using principal component analysis and/or regional covariance descriptors. In certain aspects, a training set of pre-defined intraluminal images known to contain an object is generated. The principal components of the training set can be calculated in order to form an object space. An unknown input intraluminal image can be obtained and projected onto the ...

    7. Systems for correcting distortions in a medical image and methods of use thereof

      Systems for correcting distortions in a medical image and methods of use thereof
      The invention relates generally systems for correcting distortion in a medical image and methods of use thereof. Methods and systems for displaying a medical image of a lumen of a biological structure, generally comprise obtaining image data of a lumen of a biological structure from an imaging device, correcting the image data for translational distortions, in which correcting is accomplished without reference to another data set, and displaying a corrected ...

    8. System Method For Resampling Optical Coherence Tomography Signals In Segments

      System Method For Resampling Optical Coherence Tomography Signals In Segments
      A system and method for resampling interference datasets of samples in segments, in a swept- source based Optical Coherence Tomography (OCT) system. The resampling is preferably performed within a Field Programmable Gate Array (FPGA) of the OCT system, the FPGA preferably having Fourier-transform based signal processing capabilities such as Fast Fourier Transform (FFT) cores. Resampling the interference datasets in segments provides a flexible approach to resampling that makes efficient use ...

  2. About Volcano Corporation

    Volcano Corporation

    Volcano Corporation. Cardiology Systems. Volcano Corporation develops, manufactures and commercializes a broad suite of intravascular ultrasound (IVUS).  Volanco purchased Cardiospectra and Axsun Technologies with an eye toward developing intravascular OCT systems.  In 2013 Volcano announced it was canceling its OCT development and in 2014 Volcano announced it was divesting Axsun Technologies.
