Methods, endoscopic systems, and non-transitory, machine-readable storage media for adjusting an exposure of an endoscopic system are described. In an embodiment, the methods include emitting light with a light source into a proximal end of an endoscope light pipe; generating received light signals with a photodetector based on light received through the endoscope light pipe by the photodetector; displaying, with a display module, images based on the received light signals having a current image brightness; monitoring the received light signals for changes to the current image brightness; and adjusting a light source illuminance level, and in some embodiments a photodetector gain and exposure time, based on the current image brightness to maintain a target image brightness of the display module. In an embodiment, a brightness adjustment step size is less than a just-noticeable difference in brightness of an eye and is directly proportional to the current image brightness.

An imaging system (100) comprises a multimode waveguide (Wm) configured to receive input light (Li) from a light source (20) into its proximal side (13p) and output a corresponding speckle pattern (Pn) based on the input light (Li) out of its distal side (13d) for illuminating a sample (S) to be imaged. A single-mode waveguide (Ws) is connected to the multimode waveguide (Wm) for coupling the input light (Li) from the light source (20) to the multimode waveguide (Wm). The multimode waveguide (Wm) has a relatively short length (Zm) and relatively high flexural rigidity (R) for maintaining a unique relation between the input characteristic (λ,A) of the input light (Li) into the multimode waveguide (Wm) and a spatial distribution (Ixy) of the speckle pattern (Pn). The single-mode waveguide (Ws) may be relatively long and flexible (F) for allowing movement of the short rigid multimode waveguide (Wm).

A mounting member includes: a body portion provided in a camera head including an image sensor, the body portion being rotatable about a first axis that passes through the body portion and connectable with an endoscope; a locking protrusion provided in the body portion and configured to lock with the endoscope; a detachable button configured to be movable with respect to the body portion and control attachment and detachment of the endoscope to and from the body portion; and a spring whose load applied to the locking protrusion changes according to an advancing/retreating operation of the detachable button with respect to the body portion. The detachable button includes a sliding portion extending in an advancing/retreating direction with respect to the body portion and configured to slide with respect to the body portion. The body portion includes a guide portion configured to guide a moving direction of the sliding portion.

Provided herein are systems for monitoring a subject's teeth during orthodontic treatment. In particular, described herein are apparatuses having a fixed focal length for coupling to a patient's smartphone, including a built-in lip/cheek retractor. These smartphone dental imaging apparatuses may be configured to easily and robustly interface with the user's smartphone to allow capture of dental images.

A system and method of providing composite real-time dynamic imagery of a medical procedure site from multiple modalities which continuously and immediately depicts the current state and condition of the medical procedure site synchronously with respect to each modality and without undue latency is disclosed. The composite real-time dynamic imagery may be provided by spatially registering multiple real-time dynamic video streams from the multiple modalities to each other. Spatially registering the multiple real-time dynamic video streams to each other may provide a continuous and immediate depiction of the medical procedure site with an unobstructed and detailed view of a region of interest at the medical procedure site at multiple depths. A user may thereby view a single, accurate, and current composite real-time dynamic imagery of a region of interest at the medical procedure site as the user performs a medical procedure.

A control device includes an image quality control unit configured to control image quality of an image for display on a basis of optical axis angle information with reference to a scope axis of an endoscope and an image signal acquired by an image sensor. The optical axis angle information is information detected by information obtained by acquiring light source angle information controlled by an imaging device.

The present technology relates to an imaging device and an electronic apparatus capable of adjusting a focus position and an image stabilization position with high accuracy. There are provided a lens that converges object light, an imaging element that photoelectrically converts the object light received from the lens, a circuit base that includes a circuit configured to output a signal received from the imaging element to an outside, an actuator that drives the lens with a PWM (Pulse Width Modulation) waveform in at least either one of an X-axis direction and a Y-axis direction, and plural detection units that are so disposed as to face plural first coils included in the actuator, and detect magnetic fields generated by the first coils. The present technology is applicable to an imaging device.

Compositions and methods for assessing blood vessels and organs of the body are disclosed herein, specifically methods for assessing the vasculature of the eye.

Offset illumination using multiple emitters in a fluorescence imaging system is described. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The emitter comprises a first emitter and a second emitter for emitting different wavelengths of electromagnetic radiation. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of a hyperspectral emission, a fluorescence emission, and/or a laser mapping pattern.

Device for inspecting a cavity of a patient comprising a retractor body, extending along a longitudinal axis between a distal end and a proximal end, and a handle applied or fixed to the proximal end of the retractor body.

The retractor body has a distal portion having a substantially tubular shape and a proximal portion extending from the distal portion in a diverging fashion. The distal portion defines a retraction zone of an internal cavity of a patient and internally delimits an internal volume accessible from a rear access opening made on the proximal portion, wherein said distal portion of the retractor body has at least one front and/or lateral opening to allow access to the mucosa or tissue of the patient from said internal volume. The device further comprises at least one support seat arranged in the proximal region of the retractor body and configured to supportingly receive a front surface of a laser head, said at least one support seat being arranged in a radially external position with respect to an external profile of the proximal portion.
