An object of the invention is to provide a medical diagnosis support device, an endoscope system, and a medical diagnosis support method where the visibility of a recognition result of a medical image is high. A medical diagnosis support device according to an aspect of the invention includes an image acquisition section that acquires medical images in time series, a detection section that detects a region of interest included in the medical images, a discrimination section that performs the discrimination of the medical images, a display control section that causes a display device to display any one of a result of the detection or a result of the discrimination, and a setting section that sets a waiting time required until the display is performed after the detection or the discrimination is performed. In a case where an object to be displayed is switched between the result of the detection and the result of the discrimination, the display control section causes the result of the detection or the discrimination to be displayed when the waiting time has passed after the detection or the discrimination is performed.

An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared. The images are displayed to a surgeon for use in surgery.

A surgical suturing tracking system is disclosed. The surgical suturing tracking system is configured to detect and guide a suturing needle during a surgical suturing procedure. The surgical suturing track system comprises a control circuit configured to predict a path of a needle suturing stroke after receiving an input from a clinician, detect an embedded tissue structure, and assess proximity of the predicted path and the detected embedded tissue structure.

A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

A surgical camera system includes a camera with at least one sensor configured to capture image data comprising a first range of wavelengths and a second range of wavelengths. An excitation light source emits an excitation emission at an excitation wavelength. A controller is in communication with the at least one sensor of the camera. The controller is configured to process the image data from the at least one sensor and detect at least one fluorescent portion of the image data in response to a fluorescent emission generated by a fluorescent agent in the second range of wavelengths. The controller is further configured to generate enhanced image data demonstrating the at least one fluorescent portion of the surgical implement in the image data.

Systems, methods, and devices for laser mapping and color imaging with increased dynamic range are disclosed. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation, wherein the pixel array comprises a plurality of pixels each configurable as a short exposure pixel or a long exposure pixel. The system includes a controller comprising a processor in electrical communication with the image sensor and the emitter. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises a laser mapping pattern.

A light emitting device (1) is a light emitting device for use in a photodynamic therapy. The light emitting device includes: a solid-state light-emitting element (2) that emits primary light in which an energy density is 0.5 W/mm.sup.2 or more; and a wavelength converter (3) including a first phosphor (4) that emits first wavelength-converted light (7). The first wavelength-converted light has a light component across at least a whole of a wavelength range of 700 nm or more and less than 800 nm. Energy of fluorescence emitted from the wavelength converter is 100 mW or more. A medical device includes the light emitting device.

Systems and methods are configured for combined fluorescence imaging and white light imaging of tissue such as during surgical endoscopic procedures. A chip-on-tip type endoscope can be equipped with both white light and blue light LEDs. A single camera or dual cameras are configured with backside illuminated CMOS image sensor(s) to receive and process the white light and fluorescence images. The light sources, image sensors and image processing circuitry are configured to synchronously emit light and record pixels for visible white light and fluorescence frames alternately. Global or quasi-global shuttering can be used on the image sensor(s). A modified color filter array and other filters can be provided to enhance fluorescence imaging capabilities. Insufflating gas clears debris from the camera field of view and aids in moving he cannula distally through a body passageway.

A method and system for calibrating fluorescence data in a multimodality image acquired from a vessel imaged by an imaging catheter. A fluorescence signal acquired by a first modality is calibrated by applying a first calibration factor based on a lumen distance and/or radiation angle from the catheter to the vessel wall. If a parameter of the calibrated fluorescence signal is different from a predetermined condition, a user is prompted to manually select a lumen boundary and/or a region of interest (ROI) on the image of the vessel. An optical attenuation property of the selected boundary and/or ROI is calculated based on backscattered radiation collected by a second modality, and the fluorescence signal is further calibrated by applying a second calibration factor based on the optical attenuation property.

Surgical sealing ports for use with surgical instruments for access of a natural body orifice are provided. In one exemplary embodiment, a surgical sealing port includes a seal housing and at least one retention element. The seal housing is configured to be at least partially disposed within a natural body orifice and defining a plurality of ports. The plurality of ports includes at least one first port configured to control the ingress and egress of fluid between an interior volume of the natural body orifice and an ambient environment, and at least one second port that is configured to form a seal around an instrument inserted therethrough. The at least one retention element is arranged on an exterior surface of the housing and configured to affix the housing to the natural body orifice. Methods for using the same are also provided.
