Ingestible device with propulsion and imaging capabilities
Introduced here is an ingestible device comprising a capsule, a camera, an antenna, and a propulsion component. The camera can capture images of various in vivo environments as the ingestible device traverses the gastrointestinal tract, and these images can be wirelessly transmitted to an electronic device located outside of the living body. The images may be transmitted to the electronic device for review by an operator responsible for controlling the ingestible device.
Endoscope system, processor, calibration apparatus, and endoscope
An endoscope system includes an endoscope having a position/angle sensor and an amplifying circuit, a memory configured to store output error sensitivity data and a first wiring resistance value, and a processor including a signal processing circuit configured to process an output signal from the amplifying circuit. The signal processing circuit corrects an error of the output signal based on a value obtained by multiplying a difference between the first wiring resistance value and a processor wiring resistance value by the output error sensitivity data.
Otoscope
An otoscope and method for visualizing compliance of the tympanic membrane in response to a pressure stimulus. The otoscope includes a handle, a housing, a laser assembly configured to selectively project a grid array of dots on a tympanic membrane of a patient, a camera configured to selectively capture activity of the tympanic membrane, a pressure transducer configured to selectively apply a stimulus to the tympanic membrane, a display pivotably coupled to the handle, and a controller. The display is configured to display the tympanic membrane in true color and a two-dimensional interpolated surface plot representing activity of the tympanic membrane in response to the stimulus.
Recording device, image observation device, observation system, control method of observation system, and computer-readable recording medium
A recording device includes: a memory; and a processor including hardware. The processor is configured to generate, based on temporal change in plural sets of image data that have been generated by an endoscope and arranged chronologically, biological information on a subject, associate the plural sets of image data with the biological information to record the plural sets of image data with the biological information into the memory, and select, based on the biological information, image data from the plural sets of image data that have been recorded in the memory to generate three-dimensional image data.
Endoscopic image acquisition system and method
Provided are endoscopic image acquisition system and method that make observation of images easier when images are collected. The endoscopic image acquisition system includes a wavelength pattern changing unit that changes a wavelength pattern of irradiation light with which a part to be observed in a body cavity of a patient is irradiated or returning light from the part to be observed. Images of an observation wavelength pattern are captured at a certain frame rate. In response to acceptance of an acquisition instruction, images of a plurality of wavelength patterns different from one another are sequentially captured. The images of the plurality of wavelength patterns different from one another are stored in a storage unit. An image of a wavelength pattern other than the observation wavelength pattern is set not to be displayed.
Correction of margin lines in three-dimensional models of dental sites
A method includes receiving first intraoral scan data comprising a first depiction of a dental site comprising a preparation tooth; generating a virtual three-dimensional (3D) model of the dental site using the first intraoral scan data; processing at least one of the first intraoral scan data or data from the virtual 3D model to identify a margin line of the preparation tooth, wherein at least a portion of the margin line is unclear; outputting instructions to generate second intraoral scan data of the dental site depicting the portion of the margin line that is unclear; receiving the second intraoral scan data; and updating the virtual 3D model of the dental site using the second intraoral scan data, wherein the portion of the margin line that was unclear in the virtual 3D model is replaced with information from the second intraoral scan data.
Imaging system and method
An imaging connector includes a proximal side and a distal side. The proximal side includes a light input opening and an image output opening. The distal side includes a light output opening and an image input opening. The imaging connector is operable to (i) transmit light from the light input opening to the light output opening, and (ii) transmit an image from the image input opening to the image output opening.
SYSTEM AND METHOD FOR 3D SCENE RECONSTRUCTION WITH DUAL COMPLEMENTARY PATTERN ILLUMINATION
An apparatus, system and process for utilizing dual complementary pattern illumination of a scene when performing depth reconstruction of the scene are described. The method may include projecting a first reference image and a complementary second reference image on a scene, and capturing first image data and second image data including the first reference image and the complementary second reference image on the scene. The method may also include identifying features of the first reference image from features of the complementary second reference image. Furthermore, the method may include performing three dimensional (3D) scene reconstruction for image data captured by the imaging device based on the identified features in the first reference image.
METHOD AND SYSTEM FOR IMAGE-GUIDED PROCEDURES WITH SENSING STYLET
A medical apparatus includes: an endoscopic subsystem, a medical instrument, an imaging stylet; and a system console with data-processing capability. This image-guided system calculates, in-real time, a position of the instrument relative to a target within patient body to guide and control accurate placement of the instrument to the target. The stylet is configured to acquire image data intra-operatively. In addition, the stylet has a sensing region along a flexible distal portion of its length. The system console communicates with the stylet to calculate the position of the instrument inside a patient by using intra-operative image data of surrounding tissue acquired by the stylet, distributed strain data measured by the console within the sensing region of the stylet, and preoperative image data of the patient anatomy. The stylet incorporates optical guides that are advantageously used both for imaging and for distributed strain sensing, enabling miniaturization of the stylet for accomplishing an intra-operative image guidance and navigational feedback without increasing invasiveness or compromising safety of the guided medical procedures.
Method and device for color correction of two or more self-illuminated camera systems
A device and method for color correction of two camera systems each having an imaging device and an illumination source. The camera systems are separately white balanced with the imaging device outside a scene. Their white balance gains and color correction matrices are saved. Based on the measurements, combined white balance gains and combined color correction matrices are computed and saved. Thereafter, with the imaging devices in a scene, performing white balancing by measuring the R, G, and B values of both imaging devices together, and then white balancing by measuring the R, G, and B values of each separate imaging device with the other camera system's light off. Comparisons are made of each camera's scene measurements against the combined scene measurements. If they are significantly different, the combined light set of white balance gain and color correction matrix is applied to digital signal processing paths of each camera system.
