RaySearch Laboratories AB (publ) announced that QST, National Institutes for Quantum Science and Technology in Chiba, Japan, has selected the treatment planning system RayStation®? for clinical use at the QST hospital. The order was received and delivered in the first quarter of 2024.

Already in 2018 RaySearch and NIRS (today known as QST) entered a partnership, including a long-term licensing agreement that enabled RaySearch to integrate the microdosimetric kinetic model (MKM) developed at NIRS, into the RayStation treatment planning system. This was followed by a research collaboration agreement in 2022, with focus on advancing ion beam therapy via the pencil beam scanning technique. The aim of the researchers from RaySearch and NIRS was to explore areas such as radiobiological modeling of ion-beam irradiation and dose fractionation, robust beam delivery and plan optimization algorithms. QST's purchase of RayStation is a logical step and manifests the long and fruitful research collaboration.

Some of the advanced technologies included are multicriteria optimization, deformable image registration, dose tracking over multiple treatments and adaptive radiotherapy.on beam therapy is a highly advanced form of radiation therapy in which tumors are treated with protons oravier ions such as helium or carbon.
