1. A system, comprising:
a head-worn display comprising a view-area and a renderer configured to render onto the view-area;
a central controller comprising a processor and memory;
an augmented-reality controller comprising a processor and memory;
an imaging sensor comprising a radiation sensor, the imaging sensor configured to sense phenomena in a patient's body based on a reception of radiation that has passed through the patient's body; and
an imaging controller comprising a processor and memory, the imaging controller configured to: (i) generate an imaging-datastream formatted to contain gradient data having at least one range of values based on the sensed phenomena and (ii) transmit, to the central controller, the imaging-datastream,
wherein the central controller is configured and programmed to:
receive the imaging-datastream;
automatically generate, from the imaging-datastream, a high-contrast videostream comprising monochromatic data having a selected value from a plurality of specified values by automatically converting the gradient data to the monochromatic data, wherein surgical tools and vascular tissue are represented with a dark monochromatic color corresponding to a first value of the plurality of specified values and surrounding non-vasculature tissue is represented with a light monochromatic color corresponding to a second value of the plurality of specified values, the dark monochromatic color being darker than the light monochromatic color; and
transmit, to the augmented-reality controller, the high-contrast videostream,
wherein the augmented-reality controller is configured to: (i) receive the high-contrast videostream and (ii) instruct the head-worn display to render the high-contrast videostream such that the surgical tools and the vascular tissue are rendered with the dark monochromatic color, and
wherein the head-worn display is configured to display the high-contrast videostream such that: i) the surgical tools and the vascular tissue are rendered onto the view-area in the dark monochromatic color and ii) the surrounding non-vasculature tissue is rendered onto the view-area in the light monochromatic color, and
wherein the light monochromatic color is transparent such that images of environments beyond the head-worn display transmit through the light monochromatic color to be visible by a wearer of the head-worn display.
