Abstract: An image processing apparatus and method are provided whereby one or more memories stores instructions which, when executed by one or more processors configures the one or more processors to perform operations including obtaining image data stored in memory of a processing device, defining one or more regions of the image to be processed based on luminance values of the region, providing, as input data, the one or more defined regions of the image to an classifier that has been trained to use image data to estimate noise in an image to output a prediction that the input data is in a first class or a second class, calculating an average by predicted class, and labeling the obtained image as the first class or second class based on the calculated average.

Abstract: A fiber optics rotary joint (FORJ) connects a system console to a probe having a rotatable core, and transfers rotational motion to the probe core. The FORJ comprises a stationary optical fiber in optical communication with a rotatable optical fiber, a motor having a hollow shaft, and a fiber connector attached to a distal end of the hollow shaft. The motor is configured to rotate the rotatable optical fiber relative to the stationary optical fiber. The rotatable fiber is attached to the proximal end of the hallow shaft and connected to the fiber connector. The distal end of the stationary optical fiber is directly opposed to and aligned with the proximal end of the rotatable optical fiber such that optical axes of the stationary and rotatable optical fibers are substantially collinear with the rotational axis of the motor. The fiber connector transfers optical power and torque to the probe core.

Abstract: A method for reproducing a lumen curve to a given tolerance in at least one image in optical coherence tomography (OCT). Examples of applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, cardio applications, and being obtained via one or more optical instruments, such as, but not limited to, catheters. The method may include obtaining a set of original points of the curve that correspond to measurements from an optical imaging device. Filtering the set of original points using at least one criteria to obtain a subset of original points. The method may also include determining if the subset of original points is less than a predetermined threshold and adjusting the at least one criteria to increase an amount of original points included in the subset of original points when it is determined that the subset of original points is less than the predetermined threshold.

Abstract: A system, method, and computer-readable media configured to process image data for detecting blind spot locations in multimodality images acquired by an imaging catheter. The method comprises: acquiring a multimodality image of a blood vessel, the multimodality image includes first image data co-registered with second image data collected simultaneously by scanning an inner wall of the blood vessel with light of two or more wavelengths transmitted through the catheter; analyzing the first image data to identify a characteristic feature of the blood vessel; detecting, based on the characteristic feature of the blood vessel, a potential blind spot location of the second image data in the multimodality image; and displaying on a display device the multimodality image with a marker showing the potential blind spot location of the second image data in relation to the first image data.

Abstract: An optical coherence tomography (OCT) system comprises: an imaging catheter; a calibration phantom removably arranged at least partially surrounding the distal end of the catheter; and a processor configured to control the catheter to acquire OCT images. The phantom has known dimensions and specific optical properties which provide non-changing calibration fiducials that span the imaging range of the system. The phantom is imaged by the catheter upon first connection to the system. The processor calculates a thickness of the phantom in the OCT image, and preforms z-offset calibration by setting the position of a phantom surface in the OCT image to a known nominal value. The known nominal value is related to one or more of the known thickness of the phantom or a diameter of the catheter sheath or a nominal angle of the light beam or the imaging range of the system.

Abstract: A steerable medical instrument, such as a catheter or endoscope, comprises a tubular body having non-steerable section and steerable sections arranged from a proximal end to a distal end thereof. The tubular body defines a tool channel and a plurality of wire conduits formed along the wall of the tubular body. The steerable section includes wire-guiding members arranged in lengthwise direction alternated with void regions. A control wire arranged in a first conduit within the wall of the tubular body is connected to an actuator and transfers an actuating force to bend the steerable section. An electrical cable arranged along the wall of the tubular body has strain relief elements. The strain relief elements are portions of the cable arranged in at least one void region and configured to freely move within the void regions to provide strain relief to the electrical cable when the tubular body bends.
