Embodiments of the present invention provide enhanced visualization of laparoscopic space or the like perhaps with multiple camera views on a screen or multiple screens, a camera box, scopes, or the like.

An endoscope includes a first frame, a second frame, a first clearance, an enlarged diameter section, a distal end constituent member, and a second clearance, and a set height of the enlarged diameter section is set to be greater than a magnitude of the first clearance to which the second clearance is added.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

A rigid-scope optical system includes: an image-formation optical system that causes an image in each of wavelength bands to be formed in a predetermined imaging device, the wavelength bands including a fluorescence wavelength band and a visible light wavelength band; and a color-separation-prism optical system having a dichroic film that separates an optical path of light to be imaged into an optical path of the visible light wavelength band and an optical path of the fluorescence wavelength band, in which the image-formation optical system causes the respective images to be formed in a fluorescence imaging device and a visible light imaging device, the fluorescence imaging device and the visible light imaging device being disposed to cause an amount of misalignment to correspond to a difference between an optical path length of fluorescence and an optical path length of visible light.

According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.

An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe 500 can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe 500 can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe 500 may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

An illumination optical system is formed into a substantially U shape or a partial shape of the substantially U shape as a cross-sectional shape viewed from a distal end side of a longitudinal axis such that an observation optical system is arranged inside, and has a plane as an incidence surface on which light directed toward the distal end side from a proximal end side along the longitudinal axis is incident, a plane as an emission surface from which the light is emitted as illumination light toward a subject, and a reflection surface which is inclined to direct the light incident on the incidence surface toward the emission surface when viewed from the distal end side of the longitudinal axis.

A fluorescence imaging system is configured to generate a video image onto a display. The system includes a light source for emitting infrared light and white light, an infrared image sensor for capturing infrared image data, and a white light image sensor for capturing white light image data. Data processing hardware performs operations that include filtering the infrared image data with a first digital finite impulse response (FIR) filter configured to produce a magnitude response of zero at a horizontal Nyquist frequency and a vertical Nyquist frequency. The operations also include filtering the infrared image data with a second digital FIR filter configured with a phase response to spatially align the white light image data with the infrared image data. The operations also include combining the white light image data and the infrared image data into combined image data and transmitting the combined image data to the display.

An image capturing device comprises a first elongated body portion formed of a first material and a second elongated body portion coupled to a proximal end of the first body portion. The second body portion is formed of a second material having a greater heat conductivity than the first material. The device further comprises an imaging window coupled to a distal end of the first body portion, a first housing within the first body portion, an image sensor mounted to the first housing, and an image processor mounted to the first housing and coupled to receive electrical signals from the image sensor. The device further comprises a second housing within the first body portion. The second housing is coupled to the first housing and to the window such that heat generated by the image sensor and image processor is transmitted through the second housing to the window.

An imaging device (010, 10, 110) comprises a first optical system (020, 20, 120) at a distal end of the imaging device, a second optical system (080, 80, 180) towards the proximal end of the imaging device, and a sensor (074, 74, 174) at the proximal end of the imaging device. The first and second optical systems and the sensor are aligned along a common longitudinal axis. The first optical system is or comprises one or more reflective and/or refractive optical components (24, 124; 22, 122) symmetrically and/or coaxially arranged with respect to the longitudinal axis, and the second optical system comprises one or more reflective and/or refractive optical components (24, 124; 22, 122) for focussing incident light towards the sensor. A calibration system (200) and method for calibrating such an imaging device, and a method of processing image data obtained from such an imaging device are also provided.
