A system for controlling a medical image capture device during surgery, the system including: circuitry configured to receive a first image of the surgical scene, captured by the medical image capture device from a first viewpoint, and additional information of the scene; determine, for the medical image capture device, in accordance with the additional information and previous viewpoint information of surgical scenes, one or more candidate viewpoints from which to obtain an image of the surgical scene; provide, in accordance with the first image of the surgical scene, for each of the one or more candidate viewpoints, a simulated image of the surgical scene from the candidate viewpoint; control the medical image capture device to obtain an image of the surgical scene from the candidate viewpoint corresponding to a selection of one of the one or more simulated images of the surgical scene.

An image of a field of view is captured by the endoscope and a portion of the image is displayed on a display. A popup image is generated and displayed upon image analysis identification of an occurrence of bleeding or motion of edges of an incision that is within the field of view, but outside the portion of the field of view displayed on the display.

The present specification describes a method for determining the distance of an object from the tip of an endoscope during an endoscopic procedure, wherein at least one lens is configured to converge light from outside the tip onto a sensor that includes a plurality of photodiodes a portion of which are adjacent pairs of photodiodes configured to be phase detection pixels. The method includes receiving light into each adjacent pair of photodiodes, wherein said light is reflected off a surface of said object; determining a first response curve to said light for a first photodiode of said adjacent pair of photodiodes and a second response curve to said light for a second photodiode of said adjacent pair of photodiodes; identifying an intersection between the first response curve and the second response curve; and using data derived from said intersection to determine said distance to the object.

This disclosure relates to the minimally invasive medical technical field, and specifically, to a device of anti-fogging endoscope system including a beam of a near-infrared light for anti-fogging, which is coupled into an endoscope imaging optical channel in combination coaxially and is transmitted to the front optical window sheet, the visible light passes through the front optical window sheet, and the near-infrared light is absorbed by the absorption characteristics of the front optical window sheet to raise the temperature of the front optical window sheet. The device is also provided with a cut filter for eliminating the impact on image quality caused by the near-infrared stray light, so that the illumination light source of the prior-art endoscope is not necessary to be changed. It is suitable to integrate the coaxial coupling module with a camera handle or adapter and is more convenient to operate the device.

An example imaging apparatus that can operate at shortwave infrared (SWIR) wavelengths are provided. An example imaging apparatus may include a fiber optic bundle, a distal lens, an illumination assembly, and an imaging detector. The fiber optic bundle may comprise a plurality of fibers and may be configured to guide light energy at a SWIR wavelength. The distal lens may be disposed on a distal end of the fiber optic bundle and the distal lens configured to focus light energy at the SWIR wavelength. The illumination assembly may be configured to output illumination at the SWIR wavelength adjacent to the distal end of the fiber optic bundle toward an object. The imaging detector may be operably coupled to a proximal end of the fiber optic bundle and configured to receive imaging light energy at the SWIR wavelength reflected from the object and guided through the fiber optic bundle.

A stereo-endoscope for observation and analysis of an object, comprising a shaft with distal and proximal ends, illuminating means for illuminating the object, and stereoscopic imaging means which transfer light radiated by the object from the distal end to the proximal end. Light of a first imaging channel is fed into a first sensor, and light of a second imaging channel is fed into a second sensor. Both sensors contain mutually different beam splitters, which split the light into four light beams. One light beam from each of the sensors is deflected onto one sensor each; these two sensors are identical. The signals detected there are assembled to form a stereoscopic image. The stereo-endoscope comprises mutually different manipulating means for the other two light beams; by means of suitably-tuned image-processing algorithms, two different monoscopic images containing information complementary to each other and to the stereoscopic image are generated.
