[quote=“Mina, username:Mina”] [quote]Can you comment on what percentage of patients are fully using the AlignRT workflow.[/quote] [/quote] about 90% at University Hospitals Dorset. it is only electron patient and those in a H&N shell who don’t have SGRT. we are imminently going to start using open face H&N shells and eventually may switch over electrons but we hardly treat any of those these days ---

[quote=“Mina, username:Mina”] [quote]How does AlignRT tackle center couch during CBCT for DIBH treatments?[/quote] [/quote] it is fine, we just make sure we have restored the couch position before we do the post-cbct reference capture. at the moment sgrt doesn’t gate the kV beam ---

> [@Mina](#): > > [quote]What is the installation time of the system on a clinical Linac and how long does the training takes for the users. [/quote] install time and acceptance = approx 1 day per linac phase 1 training is 2-3 days for key people. standard training they do on-site over a morning then hand hold you through patients in afternoon physics commissioning = approx 15 hours per linac ---

> [@Mina](#): > > [quote]Do you have “key-user” RTT’s? [/quote] kind of - the key people are our technique development radiographers and imaging practitioners (specialists). they are not officially named SGRT key users or anything really though but they are known to be experts on it ---
