Abstract: An optical probe comprises a light-guiding component, an optical component, a light-reflecting component that is configured to receive light from the optical component and direct the light along a path, and a correction component. The correction component lies in the path, the correction component has an optical power, and the correction component has a center of curvature that substantially coincides with an optical axis of the optical component.

Abstract: A spectrally encoded endoscopic probe. The probe has a light guiding component, a light focusing component, and a grating component. The probe is configured such that a set of light beams of multiple wavelengths are diffracted by the grating component in different orders at substantially the same angle. The set of light beams includes at least 3 light beams. Each light beam among the set of light beams is associated with a different wavelength.

Abstract: The present disclosure provides apparatuses and methods for color imaging and an increased field of view using spectrally encoded endoscopy techniques. At least one of the apparatuses includes an illumination unit having two or more spectrally dispersive gratings positioned, for example, on different planes or on the same plane but having grating vectors at an angle to each other such that bands of spectrally dispersed light propagating from the gratings propagate on different planes.

Abstract: An image processing device and method are provided that generates a window having a predetermined size and including a geometric center point to analyze the image data and identifies, as speckle data, one or more pixels of the image data positioned within the generated window. Corrected image data is generated by replacing the one or more pixels identified as speckle data with a replacement pixel value derived from pixels surrounding to the one or more pixels identified as speckle data in a case where the one or more pixels identified as speckle data is equal to or greater than a confidence threshold.

Abstract: Image acquisition apparatuses, spectral apparatuses, methods and storage mediums for use with same are provided herein. At least one apparatus includes: a diffraction element irradiated by a light; a fiber for receiving reflected scattered light from a subject; a diffraction grating dispersing the transmitted light into light fluxes of wavelength bands again; an optical system imaging the split light fluxes; and an imaging device near the focal point of the optical system. An image is changed by rotating the diffraction grating, from which a two-dimensional image is acquired. The transmitted light may be branched into two or more, and input to a collimator lens and imaged as multiple spectral sequences by the optical system. At least one apparatus may form light fluxes traveling at different angles; and may acquire spectral information of the reflected and scattered light. Preferably, for the luminous fluxes, no gap exists in an image.

Abstract: Systems, methods, and computer-readable media are provided. Some embodiments include obtaining image data of a subject and a medical device, the medical device including fiducial markers, wherein the image data includes three-dimensional image data. Information is generated representing a three-dimensional shape based on a planned insertion point for performing a medical procedure. A cropping process is applied to the image data to generate cropped image data based on the three-dimensional shape. In some embodiments, the cropped image data includes image data of at least two of the fiducial markers. Fiducial marker objects are detected within the cropped image data, and the fiducial marker objects are registered by matching a model of the fiducial markers with the fiducial marker objects.

Abstract: A first optical axis of a first optical component is caused to be at a first angle with respect to a first precision surface of the first optical component. A second optical axis of a second optical component is aligned to be at a second angle to a second flat surface of the second optical component. The second angle is equal to or derived from the first angle. The first and second flat surfaces are caused to directly face each other to allow only sliding motion between the first and second flat surfaces. The sliding motion is performed between the first and second flat surfaces until the first and second optical axes are sufficiently collinear.
