TomoTherapy treatment time slots

We are currently using 20-minute time slots for TomoTherapy treatments. In two months we will replace our linear accelerator and expect to have about 50 or more patients on TomoTherapy during installation and commissioning. I would like to investigate moving to an even shorter time slot during this time. Has anyone been able to move to less than 20 minutes per patient on TomoTherapy? We have an HDA version of Tomo.

TX Time Slots

We currently use 15-minute time slots for TomoTherapy treatments.  Have done this since installation and has worked out well.  If patients have two sites or rather long treatment times then we will utilize two time slots but this is rare.

Time Slots

We have been utilizing 15 minute time slots for years now.  We do however block extra 15 minute slots for those patients that have a longer treatment time.  Currently we have 34 patients being treated from 8-5:45 through the noon hour and we have 5 patients with two 15 minute slots due to their length of treatment or difficulty in patient set up.

Hey Tewfik,…

Hey Tewfik,

The quick answer is 'yes'.

The not-so-quick answer is 'it depends on your patient population you treat and how you plan'. I saw your presentation in Minneapolis in 2014 regarding TGN treatments on TomoTherapy. If you guys do a lot of these or similar hypofx treatments then you will need longer slots. 

We did a little study after our HDA upgrade in 2013 specifically with the intent of allowing clinics to use our dataset to help organize their treatment protocols and time slots. I ended up self-publishing it online but I think the paper is quite straightforward and honest. I just realized that you cannot upload files anymore in reply so I guess I will send you the paper to your hospital email.

I hope it helps!

Cheers, Nathan

P.s. So do you have any updated followup to your TGN treatments that you would be able to share with me? I am very interested in this. You can email me at nathan.a.corradini@gmail.com.
