Way forward: Star Trek-style hand held medical scanners - similar to this tricorder from the show - are a step closer thanks to a new breakthrough in technology
Star Trek-style hand held medical scanners are a step closer thanks to a new breakthrough in technology.
Scientists have developed a new way to create electromagnetic Terahertz (THz) waves or T-rays - the technology behind full-body security scanners.
The waves are also capable of detecting biological phenomena such as increased blood flow around tumorous growths, but current techniques are pricey and low power.
The researchers say their method of producing stronger and more continuous wave T-rays could be used to make better medical scanning gadgets, leading to innovations similar to the 'tricorder' scanner used in Star Trek.
The development could lead to medical tests becoming quicker and more convenient for patients.
