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:

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.
