RayStation 8B Launched With Machine Studying
RaySearch Laboratories launched RayStation 8B, the most recent model of the radiation remedy remedy planning system (TPS), with new advances together with some automation purposes utilizing machine studying and deep studying. Different main information in RayStation 8B embody a brand new module for analysis of robustness of remedy plans and photon Monte Carlo dose.
Machine studying signifies that the algorithms in these options be taught from the info they’re educated on, and so they be taught in a approach that resembles human logic. The purposes for automated remedy planning and automatic organ segmentation will assist enhance effectivity and consistency within the clinic. The machine studying framework delivered with RayStation 8B permits for fashions to be educated on the clinic’s accessible knowledge, and it is usually doable to make use of pre-trained fashions offered by RaySearch.
The brand new options have been developed by RaySearch’s in-house machine studying division in collaboration with Princess Margaret Most cancers Centre in Toronto, Canada, and are the primary machine studying purposes in a TPS on the radiation oncology market at present, based on the corporate.
Sturdy analysis is a brand new module in Plan Analysis, which permits environment friendly analysis of robustness of remedy plans with respect to uncertainties in affected person setup and density interpretation of computed tomography (CT). A number of situations with completely different uncertainty settings are simply created and the situations will be evaluated concurrently for fast resolution help. That is achieved via show of various robustness metrics related to the medical objectives of the remedy.
Enhancements for photon planning embody a Monte Carlo dose engine. The Monte Carlo dose algorithm brings improved accuracy and it’s using the graphics processing unit (GPU) to allow quick dose computation. The dose for a twin arc volumetric modulated arc remedy (VMAT) plan will be computed in lower than 60 seconds, which is a minimum of one order of magnitude sooner than some other system in the marketplace, based on RaySearch. The Monte Carlo dose engine can be utilized additionally throughout optimization.
Boron neutron seize remedy (BNCT) planning has been below growth since 2017 and is now accessible in RayStation 8B. BNCT is a kind of radiation remedy that permits focusing on of most cancers on the mobile stage. BNCT planning in RayStation is developed along with Sumitomo Heavy Industries Ltd and Neutron Therapeutics Inc.
RayStation 8B additionally provides varied enhancements and enhancements, together with help for straight deliverable multicriteria optimization (MCO) for VMAT, collimation of particular person power layers with the Adaptive Aperture of the Mevion S250i Hyperscan proton remedy system, and dealing with of relative organic effectiveness for proton dose.
