New tech takes radiation out of cancer screening

New tech takes radiation out of cancer screening, Science Daily, February 24, 2020, University of Waterloo

Summary:
Researchers have developed a new, inexpensive technology that could save lives and money by routinely screening women for breast cancer without exposure to radiation. The system uses harmless microwaves and artificial intelligence (AI) software to detect even small, early-stage tumors within minutes.

Researchers have developed a new, inexpensive technology that could save lives and money by routinely screening women for breast cancer without exposure to radiation.

The system, developed by researchers at the University of Waterloo, uses harmless microwaves and artificial intelligence (AI) software to detect even small, early-stage tumors within minutes.

“Our top priorities were to make this detection-based modality fast and inexpensive,” said Omar Ramahi, a professor of electrical and computer engineering at Waterloo. “We have incredibly encouraging results and we believe that is because of its simplicity.”

A prototype device — the culmination of 15 years of work on the use of microwaves for tumor detection, not imaging — cost less than $5,000 to build.

It consists of a small sensor in an adjustable box about 15 centimetres square that is situated under an opening in a padded examination table………

In addition to reducing patient wait times and enabling earlier diagnosis, Ramahi said, the device would eliminate radiation exposure, improve patient comfort and work on particularly dense breasts, a problem with mammograms.

It would also save health-care systems enormous amounts of money and, because of its low cost and ease of use, dramatically increase access to screening in the developing world.

Researchers have applied for a patent and started a company, Wave Intelligence Inc. of Waterloo, to commercialize the system and hope to begin trials on patients within six months. Three rounds of preliminary testing included the use of artificial human torsos known as phantoms. https://www.sciencedaily.com/releases/2020/02/200224111415.htm
