SGRT Forum

Hi everyone,

We currently use ABC to achieve DIBH for Lung SABR patients and EBH for Abdominal SABR patients. While effective, we've found that this method can be intrusive for patients, time-consuming to set up, and costly due to the need for mouthpieces.

Has anyone used SGRT as an alternative for managing breath holds in SABR treatments? If so, could you share your experiences, particularly in terms of effectiveness of motion management in EBH as there seems to be less information about this out there.
I'd also be interested to hear what ROIs you have found to be effective.

I Looking forward to hearing your insights!

Hi Helen,

Yes we use SGRT for Lung SABR with free-breathing and DIBH and we also use SGRT for liver SABR patients in EEBH. The only other centre I know of doing this is in Australia.

If anyone in your centre was at ESTRO a few weeks ago, I had 2 posters on the implementation of EEBH in liver SABR- you might be able to search them on the ESTRO app. If you look on my linkedin you will find the poster reference numbers.

Hope this helps!

Hi,

One of our recent physics trainees did an MSc project comparing patient monitoring using CBCT versus AlignRT for ABC liver SABR patients. They found some good correlation and this work will be carried on to look at supplementing ABC and possibly replacing it with SGRT in the future. I can put you in touch with their project supervisor to discuss the details and the results.

Thanks Colin,

That's great! I'm also doing my MSc thesis on motion management. I will be demonstrating the preliminary results of our study on the reproducibility of EEBH using SGRT in liver SABR patients at ASTRO later this year, so will be great to see your ABC results too!

Thanks,

Orla.

Thank you both! It's really helpful to hear others are looking into this as an option for motion management.
I look forward to seeing how your studies compare and will get in touch for further details.
Thanks again
