The radiation oncologist makes the final judgment regarding acceptability of the dose distribution and beam arrangement.
Sam Hancock, Ph.D., ABR, ABMP, Chief Physicist, says the Physics staff is responsible for the integrity of the information and data in the treatment planning computer, and the accuracy of the calculations. “That’s why it’s very important to have a resident physicist on staff,” he says.
The data from the treatment planning computer is then transferred to the Novalis treatment machine and is used to monitor and control the delivery of the treatment.
“It’s a very precise process,” says Hancock. “We have to ensure the radiation output is calibrated accurately, We have to ensure that we have precise and accurate beam localization, We have to test the image guided positioning system to ensure precision and accuracy. If a single link is weak or missing, it can cause the process to break down.“
