Systems and methods to detect and display endovascular features

In part, the disclosure relates to method for identifying regions of interest in a blood vessel. The method includes the steps of: providing oct image data of the blood vessel; applying a plurality of different edge detection filters to the oct image data to generate a filter response for each edge detection filter; identifying in each edge detection filter response any response maxima; combining the response maxima for each edge detection filter response while maintaining the spatial relationship of the response maxima, to thereby create edge filtered oct data; and analyzing the edge filtered oct data to identify a region of interest, the region of interest defined as a local cluster of response maxima. ...

Vascular data processing and image registration systems, methods, and apparatuses

In part, the invention relates to processing, tracking and registering angiography images and elements in such images relative to images from an intravascular imaging modality such as, for example, optical coherence tomography (oct). Registration between such imaging modalities is facilitated by tracking of a marker of the intravascular imaging probe performed on the angiography images obtained during a pullback. ...

Intravascular measurement and data collection systems, apparatus and methods

A method and apparatus for determining properties of a tissue or tissues imaged by optical coherence tomography (oct). In one embodiment the backscatter and attenuation of the oct optical beam is measured and based on these measurements and indicium such as color is assigned for each portion of the image corresponding to the specific value of the backscatter and attenuation for that portion. ... Lightlab Imaging Inc

Gradient index lens assembly-based imaging apparatus, systems and methods

In part, the disclosure relates to a lens assembly. The lens assembly can be used to direct light for sensing and imaging. ... Lightlab Imaging Inc

Stent planning systems and methods using vessel representation

In part, the disclosure relates to determining a stent deployment location and other parameters using blood vessel data. Stent deployment can be planned such that the amount of blood flow restored from stenting relative to an unstented vessel increases one or more metrics. ... Lightlab Imaging Inc

Apparatus and method of image registration

A method for bringing an ivus and an oct image into register. In one embodiment, the method includes obtaining an ivus image of an area of a lumen; obtaining an oct image of the same area of the lumen; determining the same asymmetry in each of the ivus and oct images; and overlaying the ivus and oct images and rotating them with respect to one another until the asymmetry in each of the ivus and oct images are in register, and determining the angle of rotation that resulted in the registration. ... Lightlab Imaging Inc

Methods and apparatus for swept-source optical coherence tomography

In one embodiment of the invention, a semiconductor optical amplifier (soa) in a laser ring is chosen to provide low polarization-dependent gain (pdg) and a booster semiconductor optical amplifier, outside of the ring, is chosen to provide high polarization-dependent gain. The use of a semiconductor optical amplifier with low polarization-dependent gain nearly eliminates variations in the polarization state of the light at the output of the laser, but does not eliminate the intra-sweep variations in the polarization state at the output of the laser, which can degrade the performance of the ss-oct system.. ... Lightlab Imaging Inc

Intravascular absorbable stent detection and diagnostic methods and systems

In part, the disclosure relates to systems and methods of detecting struts in a blood vessel. In one embodiment, an intravascular data collection system and an intravascular data collection probe are used. ... Lightlab Imaging Inc

Calibration and image processing devices, methods, and systems

In part, the invention relates to systems and methods of calibrating a plurality of frames generated with respect to a blood vessel as a result of a pullback of an intravascular imaging probe being pullback through the vessel. A calibration feature disposed in the frames that changes between a subset of the frames can be used to perform calibration. ... Lightlab Imaging Inc

Multimodal imaging system, apparatus, and methods

In part, the invention relates to an image data collection system. The system can include an interferometer having a reference arm that includes a first optical fiber of length of l1 and a sample arm that includes a second optical fiber of length of l2 and a first rotary coupler configured to interface with an optical tomography imaging probe, wherein the rotary coupler is in optical communication with the sample arm. ...
