Abstract: A tissue marking system includes a tissue marking beacon and a near-infrared (NIR) camera configured to detect emission of pulsatile NIR light from the tissue marking beacon. The tissue marking beacon is suitable for being injected into a tumor to mark a position and depth of the tumor for treatment. NIR light is emitted from a light-emitting diode (LED) positioned on the tissue marking beacon and is detected by the NIR camera. A pulsatile emission of NIR light from the LED is controlled to by synchronized with a data capture rate and/or detector exposure (shutter) of the NIR camera.
