T-rays technology could help develop star trek-style hand-held medical scanners

Scientists who have developed a new way to create a type of radiation known as Terahertz (THz) or T-rays - the technology behind full-body security scanners - say their new, stronger and more efficient continuous wave T-rays could be used to make better medical scanning gadgets and may one day lead to innovations similar to the “tricorder” scanner used in Star Trek.
