About

David Djajaputra is a medical physicist whose research focuses on precision radiation therapy, particularly in the domains of image-guided and motion-managed treatment delivery. His most cited work, "Ultrasound-based guidance of intensity-modulated radiation therapy" (2006, 38 citations), represents a significant contribution to improving tumor targeting accuracy by integrating non-invasive imaging with advanced radiation techniques. This work has helped lay the groundwork for real-time adaptive radiotherapy. Djajaputra has also made notable contributions to understanding organ motion during treatment, as demonstrated in his study on intrafractional pancreas motion during CyberKnife radiotherapy (2014). By analyzing fiducial tracking data from 29 patients, his research provided critical insights into the frequency and characteristics of pancreatic tumor movement, directly informing acquisition frequency protocols to enhance treatment precision. While his citation counts reflect a focused, technically rigorous body of work, Djajaputra’s impact lies in advancing the practical implementation of motion management in stereotactic body radiotherapy—a key challenge in treating abdominal tumors. His research bridges the gap between imaging physics and clinical oncology, offering valuable guidance for clinicians and physicists working to minimize treatment margins and improve patient outcomes.
