A medical diagnostic instrument or a plurality of disparate medical diagnostic instruments are configured with a common optical architecture that functionally creates a virtual eye to create closer proximity to a patient and therefore increase the field of view in regard to a target of interest. The optical system includes a distal optical element, at least one relay lens and an eyepiece lens in which the optical system can be integrated within at least one instrument or be provided using a releasable module. Additionally, at least one of a viewing assembly and illumination assembly of at least one medical diagnostic instrument can be assembled using a series of components that are connected by interlocking features.

A system comprises a dental tray comprising an array of fixed focus cameras, wherein each fixed focus camera of the first array of fixed focus cameras has a fixed position and orientation relative to one or more other fixed focus camera of the array of fixed focus cameras. The system further comprises a processing device to receive a plurality of images generated by the array of fixed focus cameras, stitch the plurality of images together based on calibration data specifying predetermined image stitching parameters for combining the plurality of images, wherein the predetermined image stitching parameters are based on predetermined fixed relative positions and orientations of fixed focus cameras from the array of fixed focus cameras, and generate a three-dimensional model of a plurality of teeth based on the stitched plurality of images.

An endoscope includes: an imaging unit that is incorporated in a distal tip of an insertion tube and images an observed site through an observation window; a plurality of first LEDs juxtaposed outside the imaging unit; and a plurality of second LEDs juxtaposed outside a region where the first LEDs are juxtaposed. The region where the first LEDs are juxtaposed and a region where the second LEDs are juxtaposed are covered with a light distribution lens, light emission of the first LED is output to an angular range smaller than a viewing angle of the imaging unit through the light distribution lens, and light emission of the second LED is output to an angular range smaller than the viewing angle of the imaging unit through the light distribution lens.

An otoscopic tip element having an axisymmetric hollow body having a substantially conical shape and made from a moldable plastic material includes a distal opening, a proximal opening, an interior surface, and an exterior surface. To maximize light transmissivity, a distal portion of the interior surface is provided with a smooth or polished surface finish and a proximal portion of the interior surface and the outer surface is provided with a textured surface finish such that light from a light source of an otoscope can be axially directed through the hollow body for emission through the distal opening, as well circumferentially through the exterior surface. The surface finish and color/tint of the speculum tip element can be adjusted or tuned to promote axial, circumferential and total light output relative to an intended medical target.

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.

A medical endoscopy/stereo colposcopy instrument is configured to selectively take stereo colposcopy images of a patient's uterus and endoscopy images of the patient's bladder or uterus. Any of the images can be white light images or images for a selected narrow wavelength band or fluorescence images. The images can be displayed individually or as spatially registered composite images to highlight selected features of the imaged anatomy. A cup-shaped device can be positioned at the patient's cervix and provided with a light source and a fluorescence camera module to monitor changes in fluorescence in response to a photoactivated substance.

The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.

The subject matter disclosed in the present invention discloses a medical imaging device comprising at least two cameras. The medical imaging device comprises an elongated and narrow distal tip connected to a rigid elongated shaft member, wherein the distal tip can comprise a front camera and a first side camera. The cameras of the disclosed medical imaging device can be configured to provide variable cameras' magnifications, which in some cases may vary from one camera to another. The distal tip can comprise some optical gear required for the medical procedures. The optical gear located in the distal tip can comprise cameras, lenses and light sources required for the camera functioning. The cameras of the medical imaging device may be provided with dissimilarity in the cameras' magnification factors. Such dissimilarities are used to show the same object in the same size in a panoramic image captured simultaneously by multiple cameras, as the multiple cameras have multiple distances to the object. In some cases, the dissimilarity in the cameras' magnification factors may be achieved by cameras with lenses, or in some cases, lens assemblies characterized by different focal lengths. In some cases, the dissimilarity in the cameras' magnification factors may be achieved by cameras with sensors characterized by different sizes.

An imaging medical instrument such as an endoscope, an exoscope or microscope having a shaft, in which an optical fiber bundle extends from the proximal to the distal end for illuminating field and in which a lens system is arranged for transmitting an image of the field. A light source inputs coupling light into the one proximal end of the optical fiber bundle with a multiplicity of selectively actuatable individual light sources arranged in an array-like manner, with a camera for capturing the transmitted image of the field of view and with a control unit for selectively actuating the individual light sources of the light source for adapting the illumination field. Here, the illumination field has a different form to the field of view. The control unit has an apparatus for analyzing the illumination situation, the apparatus being suitable and provided for analyzing the image captured by the camera in respect of changes depending on the selectively actuated individual light sources and for analyzing the field of view relative to the illumination field.

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.
