Critically, the overall aims were to understand the biological underpinning of these emerging techniques and the technical/physical parameters that must be further defined to drive clinical practice through innovative biologically based clinical trials. https://sonar.ch/global/documents/222441 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.ijrobp.2020.03.028 info:eu-repo/semantics/altIdentifier/pmid/32298811 International journal of radiation oncology, biology, physics. - 2020 Cancer Research Oncology Radiation Radiology Nuclear Medicine and imaging Understanding High-Dose, Ultra-High Dose Rate, and Spatially Fractionated Radiation Therapy. http://purl.org/coar/resource_type/c_6501
