Full-web, full compatibility, full quality for your QA tasks

ThinkQA is the first software suite dedicated for Patient Specific QA, that provides an independent secondary dose check, as well as EPID based solutions for pretreatment beam verification and in vivo dosimetry, all at once.

While on the hospital network, all of patient QA outcomes are accessible anytime and anywhere through an intuitive, ergonomic and collaborative interface.

Efficient in the precision of dose controls and innovative in its design, this full web and fully compatible solution reduces the time spent on QA tasks in the RT departments.


All-in-one Web Solution

· Follow-up of control tasks with a To-Do-List management

· Results are always available, at the palms of your hands, anywhere you are, as long as you're connected to the hospital network

· Efficient warning system

· Customizable verification protocols

· Comprehensive reports


Full compatibility

· Compatible with any TPS systems

· Compatible with all major linear accelerators: Varian, Elekta, Siemens

· Compatible with any treatment technique: IMRT, VMAT, and new expanding radiotherapy techniques using FFF (Flattening Filter Free) beam fluence

· Compatible with every heterogeneous technical platforms to provide a complete, and independent patient database for QA purposes

Implementation of a Secondary Dose Calculation System for a Magnetic Resonance Linear Accelerator


ABSTRACT

Purpose: 

To report the implementation of the secondary dose calculation software ThinkQA (TQA) v.2.0.0.60 (DOSIsoft) for a magnetic resonance-guided linear accelerator (MR-linac), following the tests of Medical Physics Practice Guideline 5.a, including dose in inhomogeneities and dose profiles.

 
Methods and Materials:

Relative Dosimetry In Monaco v.5.51.11, fields of 2×2, 5×5, 10×10, 15×15, 20×20, and 2×20 cm² were modeled at gantry 0°, at depths of 5 and 10 cm, in an isocentric configuration to obtain dose profiles and field factors. 

Dose in Inhomogeneities In Monaco, the dose was calculated with a 10×10 cm² field and 200 MU in a water-air-water phantom.

MLC Transmission The dose was measured at 5 cm depth using a 10×10 cm² field and 200 MU, with the Exradin® chamber oriented antiparallel to the magnetic field.

Patient-Specific Quality Assurance Five intensity-modulated radiation therapy (IMRT) plans (anal, abdominal, head & neck, prostate, and lung) were measured following AAPM TG-244 guidelines. The measurements were evaluated using the 3.0%/2.0 mm gamma criterion with the ArcCheck®-MR device (SunNuclear, Melbourne, FL, USA).


Results: 

Relative Dosimetry – Variations of 3.8% were reported for field factors up to 2×2 cm², comparing measured data and Monaco with TQA. MLC Transmission values were 0.25%, 0.60%, and 0.50% for experimental measurements, Monaco, and TQA, respectively. Patient-Specific Quality Assurance and Planning system commissioning were also evaluated.


Conclusion: 

The TQA software was implemented as a secondary dose calculation system for MR-linac and was clinically validated for adaptive treatment workflow using a 3%/2 mm gamma criterion, with 95% as a tolerance limit and 90% as an action limit.
