Anton Bouter of CWI's Life Sciences & Health group has been awarded the ESTRO-Elekta Brachytherapy Award at the European SocieTy for Radiation & Oncology (ESTRO 38) conference in Milan, Italy. He received the prize for the 'most innovative abstract submitted for presentation'.
The paper on which the abstract is based, is titled 'Bi-objective optimization of dosimetric indices for HDR prostate brachytherapy within 30 seconds' (Anton Bouter (CWI), Tanja Alderliesten (Amsterdam UMC), Bradley R. Pieters (Amsterdam UMC), Arjan Bel (Amsterdam UMC), Yury Niatsetski (Elekta), Peter A.N. Bosman (CWI).
In clinical practice, plan quality is judged based on dosimetric indices. However, for the purpose of efficiency, typical automated planning methods do not directly optimize dosimetric indices. This creates a mismatch between what is optimized and what is evaluated. A bi-objective optimization approach was recently proposed that directly optimizes dosimetric indices, finding many high-quality plans with different trade-offs between target coverage and organ sparing. This allows for insightful comparison of high-quality plans and patient-specific plan selection. We can now generate such sets computer-aided in as little as 30 seconds by applying GPU acceleration, which permits use in clinical practice.
