An intraoral scanner and computing system for capturing images and generating three-dimensional models. The intraoral scanner includes a handle, a mouthpiece extending from the handle, a flood illuminator projecting light from the mouthpiece, a structured light projector projecting a light pattern from the mouthpiece, and stereo camera capturing images through the mouthpiece. An optimal image of each of different materials within the captured images are combined to create a high dynamic range image. The structured light pattern in the high dynamic range image is used to determine three-dimensional measurements and create a three-dimensional model.

An otoscope may project a temporal sequence of phase-shifted fringe patterns onto an eardrum, while a camera in the otoscope captures images. A computer may calculate a global component of these images. Based on this global component, the computer may output an image of the middle ear and eardrum. This image may show middle ear structures, such as the stapes and incus. Thus, the otoscope may see through the eardrum to visualize the middle ear. The otoscope may project another temporal sequence of phase-shifted fringe patterns onto the eardrum, while the camera captures additional images. The computer may subtract a fraction of the global component from each of these additional images. Based on the resulting direct-component images, the computer may calculate a 3D map of the eardrum.

A method of controlling an intraoral scanner includes upon completion of lighting a first projection device, triggering a second projection device to initiate lighting, upon initiation of lighting the first projection device, transmitting a first camera trigger signal, a first delay circuit delaying the first camera trigger signal until completion of lighting the second projection device, and upon receiving the first camera trigger signal, a first camera and a second camera starting exposing images.

A surgical suturing tracking system configured for use with a suturing needle is disclosed. The surgical suturing tracking system comprises a spectral light emitter, a waveform sensor, and a control circuit coupled to the waveform sensor. The control circuit is configured to cause the spectral light emitter to emit spectral light waves toward a suturing needle and a tissue structure, receive an input corresponding to the spectral light waves reflected by the needle and the tissue structure and determine a distance between the needle and the tissue structure based on the received input.

An automated surgical system includes a visualization system, an imaging display system, and a surgical hub. The visualization system includes an illumination source and an imaging device. The surgical hub includes a processor and a memory device configured to store instructions. The instructions direct the surgical hub processor to control the illumination source to illuminate a surgical site and to control the imaging device to receive the imaging data. The surgical processor processes the imaging data to create display data that is transmitted over a cloud-based network to the imaging display system for display.
