The procedure is used often for patients with left-breast cancer, plus some other conditions, to reduce the negative side-effects of radiation. To prepare, follow the advice of your physician, which is typically to practice holding your breath for up to 20-30 seconds at a time, usually 2-8 times per practice session. This is what happens during DIBH treatments, so if you are ready for it, it will be easier for you. Also, if you are ready for DIBH, it enables the technique to be carried out more quickly, so you spend less time on the treatment table.
AlignRT® provides information to the radiation therapist to help quickly and accurately position you before treatment. AlignRT® then monitors your movement during radiation delivery. You may not even know it, but AlignRT® may have reduced the need to put equipment around you (like a closed face mask) to keep you in the correct position. Finally, AlignRT® can even pause the radiation if you move out of the intended position. All of this helps ensure that your treatment is as safe, quick and accurate as possible.
The only thing you may notice from AlignRT® is the red light shining from the camera units. The red light indicates that you are safely being monitored by AlignRT, which will provide continuous updates to the radiation therapists of your position.
AlignRT® uses thousands of reference points of your skin’s surface and can eliminate the need for tattoos and skin marks for certain cases. Ask your physician whether this may be applicable to your specific situation.
AlignRT® uses thousands of virtual points to ensure you are in the right position – versus three to five physical points with tattoos or marks. Several studies1-3 have also suggested this to be the case. Many of the centers using AlignRT® have actually performed their own comparison versus tattoos and found that AlignRT gives more accurate positioning as well as faster treatment sessions2. And remember – AlignRT® is also used throughout treatment to ensure that if you move from the optimal treatment position, the radiation can be paused.
During the treatment planning (simulation) sessions, your radiation team will find the right body position for you to be in during treatment and take an image with a CT scanner.
AlignRT® uses information from this image to monitor where you should be versus where you are. AlignRT® then provides information to the radiation therapist on how to position you for treatment such that the radiation will be delivered to the correct location. Once you are in the right position for treatment, AlignRT® monitors your surface for any movement out of the intended position, which can be linked to the treatment delivery machine to automatically pause radiation if required.
The real time monitoring from AlignRT® helps to ensure that you are positioned quickly and only treated when you are in the intended position.
