This was tested in people. That is the most reliable kind of research we share.
This only measured radiation doses on scans of people who were already treated.
The short version
Doctors measured how radiation spread out from small tiles left in the brain after tumor surgery.
What was studied. Researchers reviewed scans from 18 people who had brain tumor surgery. Each person had 10 to 32 tiny radiation seeds set in small tiles, placed where the tumor had been.
What they found. The radiation dose was very uneven across the treated area. Some small spots got a much higher dose than the areas around them. The tiles made one high dose spot for every 1 square centimeter of the tumor bed. The spread pattern looked much the same in every plan the team checked.
What this means, and what it doesn't
What it could mean: This kind of treatment is placed inside the brain during surgery. The study shows the dose is uneven on purpose, in a steady and repeatable way. That may help doctors plan these treatments more carefully.
What it doesn't mean: This was not a test of whether people lived longer or felt better. It was a study of dose maps on scans, not a new treatment. It says nothing about side effects. It is not a cure, and it does not change the care you can get today.
