  1. A Web interface to cloud-based Monte Carlo simulationsfor TrueBeam and C-linac Jong In Park M.S. student http://radiotherapyresearchtools.com

  2. Contents • What is the Virtual Linac • Application of Virtual Linac • How can we use (register) ?

  3. Background Varian provides ‘just’ phase space file for TrueBeam simulation • Field-independent components were not open to the public • - Target, ion chamber, carousel

  4. Varian has developed a cloud based web application, called “Virtual Linac” Linac Monte Carlo simulation as service - Enable the research community - Validatedgeometry (by Varian) - Fast computing is available w/o server Purpose of Virtual Linac Now updating .. 2013. 05. 06 version 84 (open to the public) ~ 2013. 11. 18 version 94 http://radiotherapyresearchtools.com

  5. Simulation Mechanics Amazon Web Service User Elastic compute cloud 2 Input file Dose distribution Run MC simulation http://radiotherapyresearchtools.com

  6. Use Case 1 – General case Virtual Linac Check a plan DOSXYZnrc Dose distribution http://radiotherapyresearchtools.com

  7. Virtual Linac Graphic User Interface http://radiotherapyresearchtools.com

  8. Validation of Simulation Results Presented in ‘AAPM’ meeting - Simulation results were well matched with measurement http://radiotherapyresearchtools.com

  9. Use Case 2 – What can we change ? Treatment head • Investigate changes to the treatment head • Low energy, medium energy, high energy, imaging, • Custom is also available http://radiotherapyresearchtools.com

  10. Use Case 2 – What can we change ? Originally, in TrueBeam simulation Virtual Linac Can define “Target” Using carbon target

  11. Use Case 2 – Treatment head Flattening filter - Open port (FFF), 4X, 6X, 8X, 10X, 15X, 18X, 20X Location of writing phase space file - above the jaw - below the mylar - isocenter - 95 cm from source - 150 cm from source http://radiotherapyresearchtools.com

  12. Use Case 3 – TrueBeam Developer mode • Dose distributions from TrueBeam Developer Mode XML file • - non-Monte Carlo expert • What exactly is Developer Mode? • - A method to control all motion axes and imaging through • customized XML scripts Image by Varian

  13. Use Case 3 – TrueBeam Developer mode Still to come ! TrueBeam Developer mode ‘xml’ http://radiotherapyresearchtools.com

  14. How can we use (register) ? Requirements ① Send an email to – Daren Sawkey(Varian Medical Systems) - expression of register

  15. How can we use (register) ? Requirements ② IP address as seen by the outside world (google “what’s my ip”)

  16. How can we use (register) ? Requirements ③ Amazon Web services account number • You can sign up for the Amazon Web Services (AWS) at aws.amazon.com. • After the sign up, click my account • The AWS documentation is great, and available at aws.amazon.com/documentation/ec2 for EC2.

  17. How can we use (register) ? Requirements ④ A completed license agreement He or she has the power and authority Varian the opportunity to review a draft copy of the proposed publication or presentation for review and approval at least 45 days prior to..

  18. How can we use (register) ? Once the register, you can get started - Log in to AWS

  19. How much is it? Payment ! When ? Between Amazon web service and users - Running the instance (Table) - Data transfer On-demand instance Unit: $ • “Linux” is cheaper than “window” • Can save cost reduced to 1/10 by using ‘spot request’ (highly recommend)

  20. Summary • Varian validated geometry of component • - Full TrueBeam simulation is available • Fast parallel computing • TrueBeam developer mode will be soon • Reasonable cost with ‘spot request’ • More detail information http://radiotherapyresearchtools.com

  21. Thank you for your attention !
