Forums Deep Inspiration Breath Hold Using surrogate area for tracking Reply To: Using surrogate area for tracking


To echo what Ellen said: Most of our electron boosts are planned for free breathing delivery. There are instances where DIBH electrons are called for. As you mentioned, the electron applicator blocks the immediate surface underneath. You have to omit that area directly under the cone from the tracking surface and include some additional track-able surface around the outside the applicator. Once that change is made, the setup is fairly routine.
