Cachan, France | May 6, 2026
DOSIsoft, leading provider of dosimetry software solutions for radiation oncology and nuclear medicine, announces today it will showcase its new ThinkQA 3.0 – Unified PSQA Platform during the annual meeting of the European Society for Radiotherapy and Oncology (ESTRO), taking place on May 15 -19, 2026 in Stockholm, Sweden.
As radiation therapy advances toward modern, time-constrained online Adaptive Radiation Therapy (ART), Patient Specific Quality Assurance (PSQA) processes must become faster, more reliable, and more integrated into clinical workflows. ThinkQA 3.0 addresses these challenges by combining speed, accuracy & simplicity into a unified platform designed to support online ART workflow, for both CT-Linacs and MR-Linac.
The key capabilities demonstrated at ESTRO:
- Automated PSQA: GPU-powered 3D CCC (Collapsed Cone Convolution) algorithm delivering QA results in just 1-2 minutes
- Integrated workflow: seamless integration into Elekta ONE without adding time to the routine QA process
- Centralized QA Management: all PSQA tasks (pre- & post- treatment) managed within a single and connected platform
- Simplified QA user experience: Enhanced usability and web-based access
At DOSIsoft Booth C16:51, Healthcare professionals can explore the ThinkQA 3.0 design innovation – dedicated to streamline Patient QA experience.
ThinkQA 3.0: Delivering end-to-end QA capabilities for adaptive radiation therapy
Tailored to meet the specific requirements of adaptive radiotherapy, ThinkQA 3.0 represents a significant technological breakthrough – fully compatible with online and offline adaptive workflow.
It runs around a unique, fast and optimized CCC calculation engine, validated against Monte Carlo simulations. ThinkQA 3.0 enables 3D dose distributions and 2D dose image comparisons using the same calculation engine to perform all PSQA verifications, reducing biases introduced by multiple engines.
- Secondary dose check: Independent full 3D dose calculation, automatically handling adapt-to-position and adapt-to-shape plans
- Logfile analysis: Automated pre-treatment and in vivo treatment verifications, based on machine delivery logs, and computed into 3D dose distributions
- Pretreatment check: EPID-based phantom-less QA providing instant gamma-based comparison results
- In vivo dosimetry check: EPID-based transit dosimetry QA for dose deviation detection during patient treatment
ThinkQA 3.0: Automated and integrated Quality Assurance for Elekta Linacs
Multi-vendor by design, the latest product release fits perfectly into Elekta modern radiotherapy ecosystem. It works with all Elekta linear accelerators, including Elekta Evo CT-Linac & Elekta Unity MR-Linac for adaptive radiotherapy.
In the specific case of Unity MR-Linac, the advanced CCC calculation engine takes into account the cryostat transmission and magnetic field effects on the dose distribution.
Configured using Elekta ready-to-use beam templates and models for all verifications, ThinkQA 3.0 simplifies the overall commissioning to significantly reduce workload, ensure high standards of safety and regulatory compliance.
As part of the Elekta ONE solution, ThinkQA current version will be available for workflow demonstrations at the Elekta booth #C10:87 during ESTRO.
“ESTRO provides a unique opportunity to connect with the radiation oncology community and demonstrate how ThinkQA 3.0 helps clinics keep the highest level of quality assurance in increasingly sophisticated adaptive radiotherapy, ” said Marc Uszynski, CEO at DOSIsoft, “ The new ThinkQA 3.0 – unified PSQA platform delivers outstanding performance, offering dose computation accuracy, actionable QA dosimetric insights, all via its intuitive web dashboard. Its streamlined commissioning and seamless integration with Elekta ONE represent key advantages, enabling clinical teams to deliver safer, more precise treatments with greater operational confidence.”
