Laser scanner gives 3D view inside tumors

An ultrasound scanner that provides more detailed 3D images of the deformed blood vessels within a tumor could help doctors determine the boundary between cancerous and healthy tissue during surgery.
The scanner uses a novel form of non-invasive imaging called photoacoustic tomography. This uses laser light to “twang” cells so they emit an ultrasound wave, which is then detected and used to form a 3D image.
