Researchers have developed a new method to potentially replace X-rays and ultrasounds.

French scientists from the Institut Langevin have devised a new method to detect images through opaque objects using regular, visible light. What it means for us is, it can potentially replace X-rays and ultrasounds in medical imaging applications. The scientists used a laser, a digital camera and a projector to extract images from light passing through a solid surface by interpreting how the surface makes the light scatter.

Discovery News reports:

Their experiment contained three key pieces of widely available technology: a green laser as the light source, a light modulator (which is often used in projectors), and a charged coupled device, the technology used in many digital cameras.
