ProKnow 2017 QADS TG244 H&N Plan and QA study

ProKnow system (https://proknowsystems.com/) announced their consecutive open/free access planning study excercise.

In case you would like to test your planning skills, please feel free to register and participate: 

Getting started

The announcement messages:

The ProKnow team is proud to announce the launch of our second international public plan study!

This study is unique in that we will officially analyze both: 1) plan quality, measured using the advanced scoring method of PlanIQ, and 2) TPS and delivery accuracy, tallied by collecting pre-treatment dose QA metrics. Results will highlight high performances in each category and allow you to benchmark your own results against the population for all metrics. As always, we will record video interviews with high performers to help reveal "best practices" which we will share with everyone via the ProKnow website.

Featured Meeting: The 2017 QA and Dosimetry Symposium (QADS)

As you may know, we like to run our larger plan studies in conjunction with national or international meetings where the study results are always a high-interest topic. For this study, we are very happy to be working in conjunction with the 10th annual QA and Dosimetry Symposium (QADS), which will be held February 17 and 18, 2017, in Orlando, Florida (USA). The theme of the meeting is: "Educate, Explore, Empower." That is a theme we certainly appreciate!

Featured Case: TG244 Case #5, Head & Neck

We are using a clinical test case that is included in the AAPM's TG244 guidelines, formally entitled, "AAPM Medical Physics Practice Guideline 5.a.: Commissioning and QA of Treatment Planning Dose Calculations — Megavoltage Photon and Electron Beams." Specifically, we are using case #5, a challenging head and neck test case featuring three target volumes (prescriptions of 70, 63, and 56 Gy) planned for 35 fractions using simultaneous integrated boost (SIB).

Using a TG244 dataset suits the goal of studying both plan quality and dose accuracy, both of which are vital to commissioning a treatment planning system (TPS). Everyone will participate in the plan quality portion of the study using a comprehensive scoring algorithm with 21 distinct and prioritized metrics, totaling 150 possible points. The dose QA portion of the study is optional, but encouraged, and will allow entry of analysis results from any number of QA devices and methods.
