A surgical visualization system (4000, 4006) is disclosed. The surgical visualization system is configured to identify one or more structure(s) (4001a, 4001b) and / or determine one or more distances with respect to obscuring tissue and / or the identified structure(s). The surgical visualization system can facilitate avoidance of the identified structure(s) by a surgical device. The surgical visualization system (4006) can comprise a first emitter configured to emit a plurality of tissue-penetrating light waves and a second emitter configured to emit structured light (4008) onto the surface (4005) of tissue (4003). The surgical visualization system can also include an image sensor configured to detect reflected visible light, tissue-penetrating light, and / or structured light. The surgical visualization system can convey information to one or more clinicians regarding the position of one or more hidden identified structures (4001a, 4001b) and / or provide one or more proximity indicators. In various instances, imaging data from different sources and / or obtained at different times can be integrated.

A wearable device to measure a user's physiological parameters comprising one or more biosensors, as well as a light source comprising light emitting diodes, lenses for directing light towards tissue of the user comprising blood vessels, and a detection system receiving reflected tissue light. The physiological parameters, for example hypertension, are measured with a differential measurement. For example, the physiological parameters may be associated with pulse rate and blood flow. The output signal is associated with the physiological parameters, and artificial intelligence may be used in making decisions regarding the output signal. Signal-to-noise ratio of the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity, and detecting a change. The wearable device is configured to determine that is being worn by the user and may be configured to communicate with a smartphone or tablet.

3D cameras may serve as an input to a multi-modal generative artificial intelligence (GAI) model operating on a processor coupled to a non-transitory computer readable medium. Examples of 3D cameras include direct or indirect time-of-flight sensors or structured light systems and may also be coupled to 2D cameras. The GAI comprises a vision transformer configured to analyze an item in an input video or image. The vision transformer comprises self-attention and positional encoding layers. The GAI may be trained using reinforcement learning or fine-tuning involving training images or videos, and it may perform data fusion by combining the 3D information with data from other sensors. The GAI may perform anomalous occurrence detection by training on images or videos corresponding to normal occurrences. The GAI detects differences in an image or video that fall outside of a threshold value. The GAI may also provide safeguards for privacy issues.
