An endoscope illumination device includes: an illumination optical system including an entrance surface disposed along a circumferential direction centered on a predetermined axis and provided at one-end side in the direction of the predetermined axis, an emission surface positioned at an outermost side in a radial direction with respect to the predetermined axis and radially emitting illumination light entering from the entrance surface, a diffusion surface disposed at an intermediate position of an optical path of the illumination light between the entrance surface and the emission surface and transmitting and diffusing the illumination light; and a light emitting portion disposed closer to the one-end side than the entrance surface is and emitting, toward the entrance surface, the illumination light substantially in the direction of the axis.

An example method of implementing a neural network includes selecting a first neural network architecture from a search space and training the neural network having the first neural network architecture to obtain an accuracy and an implementation cost. The implementation cost is based on a programmable device of an inference platform. The method further includes selecting a second neural network architecture from the search space based on the accuracy and the implementation cost, and outputting weights and hyperparameters for the neural network having the second neural network architecture.

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.

An endoscope system includes an image forming section configured to arrange first and second images obtained by picking up images of first and second regions of a subject to be adjacent to each other to form an image of one frame, a light source section configured to emit illumination light based on a brightness evaluation of the image to the first and second regions, a brightness-range calculating section configured to detect minimum and maximum luminance values in the first and second images, and an image processing section configured to perform a luminance shift such that a minimum or maximum luminance value of an image, a luminance range of which is smaller than a predetermined luminance range, among the first and second images coincides with a predetermined luminance lower limit or upper limit value.

A multi-camera endoscope includes a the tip section comprising: a front looking camera and a front discrete illuminator to essentially illuminate the field of view of said front looking camera; a right side looking camera and a right discrete illuminator to essentially illuminate the field of view of said right side looking camera; a left side looking camera and a left discrete illuminator to essentially illuminate the field of view of said left side looking camera; and a multi-component cover configured to cover and seal said tip section such as to essentially prevent entry of fluids from the environment of said endoscope to inner parts of said tip section. The tip cover includes removable or repositionable window components which provide access to internal components of the tip for repair or removal, without removing the main tip cover.

A catheter system includes an electronic console; a catheter having a proximal end attachable to the console and a distal end configured to house therein an optical probe; an optical fiber configured to transmit from the console to the optical probe excitation radiation of a first wavelength, and configured to return to the console an optical response signal having a second wavelength longer than the first wavelength; a detector configured to detect intensity of the optical response signal; and a processor configured to determine, based on the detected intensity of the optical response signal, whether the catheter is properly connected to the console. The optical response signal is generated within the optical fiber itself in response to transmitting the excitation radiation therethrough. The optical response signal is an auto-fluorescence signal and/or Raman scattering signal generated from the optical fiber itself.

The present specification describes a circuit board design that uses circuit boards for illuminator sets associated with the various optical assemblies. In one configuration, front and side illuminators are assembled on front and side illuminator circuit boards. Leaf connectors associated with each illuminator are provided to interface with a common base board.

One embodiment of the invention is directed to an imaging probe which comprises a first element supplying electromagnetic radiation in a forward path for illuminating a forward field of view of space in front of the probe, a second element supplying electromagnetic radiation in a sideways and/or rearward path for illuminating a sideways and/or back field of view of space alongside the probe and an image sensor. The probe further includes an imaging device in imaging paths imaging the forward and sideways and/or back fields of view onto the image sensor. Preferably the forward path, the sideways and/or rearward path and the imaging paths are unobstructed by any component of the probe. Preferably the forward and sideways and/or back fields of view are registered in a fixed spatial relationship relative to one another on the image sensor. This probe can also be used with existing endoscopes or laparoscopes so that it will be easily merged into current instruments of different manufacturers, making it easier and cheaper to use this product without the expense of a totally new endoscopy or laparoscope platform. This probe can also be used to image objects in inanimate environments as well, such as in containers, buildings, rooms, engines and pipes.

There is provided herein a tip section of a multi-viewing element endoscope, the tip section comprising: two or more side-pointing viewing elements positioned at or in proximity to a distal end of said tip section, wherein each of said two or more side-pointing viewing elements having a discrete illuminator associated therewith, wherein the field of view provided by the two or more side-pointing viewing elements covers a front and side views; a working channel configured for insertion of a surgical tool; and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.

A multi-camera endoscope includes a the tip section comprising: a front looking camera and a front discrete illuminator to essentially illuminate the field of view of said front looking camera; a right side looking camera and a right discrete illuminator to essentially illuminate the field of view of said right side looking camera; a left side looking camera and a left discrete illuminator to essentially illuminate the field of view of said left side looking camera; and a multi-component cover configured to cover and seal said tip section such as to essentially prevent entry of fluids from the environment of said endoscope to inner parts of said tip section. The tip cover includes removable or repositionable window components which provide access to internal components of the tip for repair or removal, without removing the main tip cover.
