Bye, bye, biopsy? Handheld device could painlessly identify skin cancers

Posted: 04 May 2022 10:56 AM PDT

A new device uses millimeter-wave imaging -- the same technology used in airport security scanners -- to scan a patient's skin to detect if they have skin cancer. Millimeter-wave rays harmlessly penetrate about 2mm into human skin, so the team's imaging technology provides a clear 3D map of scanned skin lesions.

The quest for an ideal quantum bit
