DOSIsoft showcases ThinkQA 3.0 at ESTRO

May 11, 2026

DOSIsoft unveiled ThinkQA 3.0, an updated patient-specific quality assurance platform for adaptive radiation therapy at the European Society for Radiotherapy and Oncology (ESTRO) annual meeting in Stockholm.

ThinkQA 3.0 is designed to support online adaptive radiation therapy workflows for both CT-Linac and MR-Linac systems, according to the company. Key features include a GPU-powered 3D collapsed cone convolution algorithm that delivers quality assurance results in one to two minutes, secondary dose check, logfile analysis, pretreatment check, and in-vivo dosimetry. The platform integrates into Elekta One and is compatible with all Elekta linear accelerators, including the Elekta Evo CT-Linac and Elekta Unity MR-Linac, DOSIsoft said.

ThinkQA 3.0 is under ongoing regulatory approval and may not be available in all markets, the company noted.

$Acute radiation-induced pneumonitis after SBRT (65 Gy, four fractions) in a 53-year-old woman with leiomyosarcoma of the uterus with a left lower lobe metastasis manifesting as a small nodule (not shown). (A) Axial dosimetric reconstruction of a CT image obtained for SBRT planning shows the metastasis receiving the maximal isodose (6500 cGy). (B) Axial CT image obtained 12 months after completion of RT shows focal ground-glass and consolidative opacities confined to the treatment plan (arrow). Note that acute lung injury with SBRT typically manifests later than with conventional RT (i.e., >12 weeks after completion of therapy), and in 25% of patients, the first CT manifestations occur more than one year after completion of RT.$
