Liquid lens provides 3D images from under the skin's surface

The aim of the technology is to detect and examine skin lesions to determine whether they are benign or cancerous without having to take a skin biopsy.

Instead, the tip of a cylindrical probe is placed in contact with the tissue and a clear, high-resolution 3D image of what lies below the surface quickly emerges.

‘My hope is that, in the future, this technology could remove significant inconvenience and expense from the process of skin-lesion diagnosis,’ said Rolland. ‘When a patient walks into a clinic with a suspicious mole, for instance, they wouldn’t necessarily have to have it surgically cut out of their skin or be forced to have a costly and time-consuming MRI done.

‘Instead, a relatively small, portable device could take an image that will assist in the classification of the lesion right in the doctor’s office.’

According to a statement from Rochester, the device accomplishes this using a liquid lens set-up developed by Rolland and her team for a process known as Optical Coherence Microscopy.
