## TL;DR

Vision RT pioneered surface-guided radiotherapy with AlignRT, ceiling cameras that track the patient's skin in 3D so treatment can be set up without tattoos and paused if the patient moves.

## Summary

Vision RT, founded in London in 2001, makes the AlignRT surface guidance system installed on linacs worldwide, used for tattoo-free set-up, deep-inspiration breath-hold in breast radiotherapy and open-mask brain radiosurgery, plus the MapRT collision-avoidance tool and simulation-room systems. It is privately held.
