Summary

This study tests whether a surface-guided system called AlignRT can position patients more accurately during stereotactic radiosurgery for brain metastases compared to standard manual methods. Twenty adults each had their position checked twice—once manually and once with AlignRT—using a partial CT scan to measure any errors. The goal is to see if AlignRT reduces positioning mistakes, which could improve treatment precision and reduce harm to healthy tissue.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: AlignRT surface-guided radiotherapy system
What this could lead to: If AlignRT proves more accurate, it could become a standard tool for precise patient positioning in brain radiosurgery, potentially reducing side effects.
What could go wrong: This is a small, early study with only 20 participants, so results may not apply broadly. The extra imaging adds time and a small radiation dose.
