摘要： A medical device includes a sensor, a processor, and non-transitory computer readable medium storing imaging instructions. The sensor captures a first raw image into a first frame of raw pixel values including a plurality of first pixel values that represent pixels of a first color and a plurality of second pixel values that represent pixels of a second color. The sensor captures a second raw image into a second frame of raw pixel values including a plurality of third pixel values that represent pixels of the second color and a plurality of fourth pixel values that represent pixels of a third color. The processor convolves the first frame of raw pixel values with the second frame of raw pixel values to generate a first extrapolated frame of pixel values in a YCrCb format and creates a processed image from the first extrapolated frame of pixel values.

摘要： An improved Optical Coherence Domain Reflectometry (OCDR) system is provided. One embodiment of this OCDR system outputs a detector signal carrying image depth information on multiple modulation frequencies, where each modulation frequency corresponds to a different image depth. The image depth information from the detector signal may be resolved by tuning to the desired modulation frequency. Another system for imaging body tissue uses multiple frequency modulators such that the light beam does not travel from an optical fiber to free space.

摘要： An endoscope may include a shaft having a longitudinal axis, a first image sensor facing a distal direction, and a second image sensor facing a lateral direction. The endoscope may further include a tubular member having a lumen, the lumen having a distal-end opening and defining a longitudinal axis through a center of the lumen. The tubular member may be movable between a first configuration and a second configuration. In the first configuration of the tubular member, the longitudinal axis of the lumen may be parallel to the longitudinal axis of the shaft. In the second configuration of the tubular member, the longitudinal axis of the lumen may extend through a lateral opening in a wall of the shaft.

摘要： A method of generating a color image using a monochromatic image sensor. The method includes sequentially illuminating a surface in a plurality of colors, one color at a time. The monochromatic image sensor captures a plurality of image frames of the surface based on the plurality of colors. The plurality of image frames are identified, and at least one feature in the target of the plurality of image frames is highlighted. Color intensities of the plurality of image frames are normalized. A color intensity map of the target for each of the plurality of image frames is generated. A correlation score is determined by comparing each color intensity map of the plurality of image frames. The color image is generated based on the correlation score.

摘要： Systems, techniques, and devices are disclosed and may include a first sensor configured to generate a first data stream, a second sensor configured to generate a second data stream, and at least one processor and at least one non-transitory computer readable medium storing data stream management instructions. When executed by the at least one processor, the instructions causes the at least processor to receive the first data stream and the second data stream, spread the first data stream using a first code to generate a first coded data stream, spread the second data stream using a second code to generate a second coded data stream, combine the first coded data stream and the second coded data stream to generate a combined data stream, modulate the combined data stream to generate a modulated data stream, and transmit the modulated data stream via a single channel.

摘要： A medical device such as a catheter or endoscope device includes an illumination light source having one or more organic light-emitting diodes (OLEDs). The OLEDs are energized to produce illumination light that is received by an image sensor or camera to produce images of tissue within a patient's body. A heat conductive polymer conducts heat away from the illumination light source.
