Is there a more precise, easier, safer way to deliver Boost and PBI?
We believe so. With today’s current solutions, motion and geometric misses over a course of PBI or electron boost treatment are possible and have the potential to jeopardize the intended outcome. Further, it has been shown that relying on the surgical scar as a proxy for the electron beam trajectory may lead to a partial geographic miss of the underlying lumpectomy cavity in greater than 50% of cases*. Of course, CT-Sim is the cornerstone of breast radiotherapy planning, but it is limited in its ability to distinguish between soft tissues.
Ultrasound, on the other hand, is regarded as one of the best imaging modalities for soft tissue definition and has clearly established itself as being a gold standard in breast imaging.
What if there was a way to achieve greater clarity and to make a significant difference for breast treatment with IGRT, just as it is making a difference in Radiotherapy of other anatomy?
Now there is.
