Images captured remotely via ultrasound

“MIT engineers have come up with an alternative method that doesn’t require contact with the body to see inside a patient. The new laser ultrasound technique leverages an eye- and skin-safe laser system to remotely image the inside of a human body. When trained on a patient’s skin, one laser remotely generates sound waves that bounce through the body. A second laser remotely detects the reflected waves, which researchers then translate into an image similar to conventional ultrasound.”  This method can image structure at a depth of 6 centimeters below the skin.   MORE
