QA records shed light on radiotherapy patient errors
The computerization of radiation therapy planning and treatment can be a double-edged sword, both reducing and increasing the risk of errors. But computerization does make treatment safer, according to a 10-year analysis of errors at Memorial Sloan-Kettering Cancer Center in New York City.

Tiny oxygen generator boosts radiotherapy
A tiny oxygen generator that can be implanted directly into the hypoxic center of tumors using a biopsy needle has been unveiled by researchers in the U.S. The micro-oxygen generator could potentially improve the efficacy of radiotherapy.

Software estimates motion effects for proton dose planning
Tumor motion due to respiration is a serious problem when it comes to ensuring that a scanned proton beam delivers the planned dose to a given target volume. Now, software simulating the delivery of a scanning proton beam to a moving lung tumor is resolving this problem.

Gold nanoparticles boost radiotherapy efficacy
By using gold nanoparticles with conventional megavoltage x-rays, researchers are predicting that tumor vasculature will receive a significant enhancement in local dose. Not only could this dose boost promote vascular shutdown in tumors, the hope is that it will suppress metastases and improve patient outcomes.
