The Value of Accuracy in Radiotherapy
Radiation therapy is delivered on a device called a linear accelerator. Targeted radiation destroys cancer cells in their very DNA.
The goal of radiation treatment is to deliver as strong and precise a dose of radiation to cancer cells as possible while not exposing healthy tissue to radiation. Over time, these devices have advanced to deliver larger, more precise doses of radiation.
Linear accelerators feature on-board CT imaging features that allow radiation oncologists to do some medical imaging during treatments, making sure the radiation is hitting its mark. But this imaging has mostly been grainy, slow and hard to interpret.
