Currently, there is no way of knowing the exact dose of radiation received by a tumor. And, because most organs shift inside the body depending on whether a patient is sitting or lying down, for example, the tumor also shifts. This technology will allow doctors to pinpoint the exact position of the tumor to more effectively administer radiation treatments.

The device is very simple, that's the beauty. This will show specifically how much radiation the tumor received.

It will be like a capsule placed into the tumor with a needle.

The radiation would be so lethal they would get a lethal dose in minutes.

The future of radiation tends to be what we call stereotactic: radiation, which focuses on the tumor and applies large doses at one time as opposed to traditional radiation which is small doses over a longer time, ... There is a gamma knife that's dedicated to treating brain lesions where, instead of radiating the brain in a three-week period, it's a one-time focused, high-powered type treatment.

My main frustration is the fear of cancer from low dose radiation, even by radiologists.
