About

Alessandro Clivio is a leading medical physicist whose research centers on advancing quality assurance (QA) methodologies in radiation therapy, with a particular focus on portal dosimetry and linear accelerator (linac) performance. His most influential work includes the development and refinement of the GLAaS algorithm, a calibration method that converts raw portal imaging images into absolute dose matrices—a critical tool for routine machine QA. This contribution, detailed in his highly cited 2008 paper (13 citations), enables more accurate and efficient testing of linac quality assurance procedures, directly enhancing patient safety and treatment precision. Clivio’s innovations have been instrumental in bridging the gap between imaging and dosimetry, providing clinicians with robust, real-time verification of radiation delivery. By streamlining QA protocols, his work has had a lasting impact on the field, helping to standardize practices in radiotherapy centers worldwide. His achievements underscore a commitment to practical, high-impact solutions that improve the reliability of cancer treatments.
