Motion included dose recon on Pinnacle TPS

Purpose

To compare dose distributions with and without intrafraction tumour motion tracking on Pinnacle Treatment Planning System

Generate motion data as a function of gantry angle (as in KIM).
The script converts VMAT beams to 2 degrees gantry separation and then splits each control point of each VMAT beam into a single static beam with the energy, MU, field aperture and MLC positions, gantry/collimator/couch angles from the control point.
Two trails 'with_motion' and 'without_motion' are created. The isocentre for each static beam are then shifted based on the basis of the tumour motion. The dose distribution for both trials are calculated.
See the attached documentation for more details.

Pinnacle Scripting and Python 2.7.9.
Traking Files format:
- Must named as "BeamName_with_LARK" and "BeamName_without_LARK" (replace BeamName with your real beam name).
- The first row is the title separated by Tab "Bin Gantry x y z (Pinnacle, mm)".
- From the second row, the data should be co-related with title and separated by Tab.
This project is heavy workloaded. Please run it when Pinnacle is free. Running after hour is recommanded.

Extract source zip file to Pinnacle "/usr/local/adacnew/PinnacleSiteData/Scripts/HotScripts/Physics/LARK_Dose_Recon_v1.4/".
Make sure this folder and sub-folder have write permission for users.
Copy Tracking files with right names and format to Pinnacle "/home/p3rtp/RadCalc/LARK/".
Run the initial script "start.Script" under the path "/usr/local/adacnew/PinnacleSiteData/Scripts/HotScripts/Physics/LARK_Dose_Recon_v1.4/".
The procedure can be hours depending on the clinical plan and Pinnacle workload.
The procedure is finihsed when the script window closed.
Each fraction must run in a new copied clinical plan. After reconstruction done, the dose and ROIs can be exported to Velocity.
Dose summary for the course can be done in Velocity.
