About
Toshihiko Umekawa has made pivotal contributions to advancing proton beam therapy, particularly through the integration of real-time tumor-tracking technology with spot scanning techniques. His most-cited work, a 2013 collaboration between Hokkaido University and Hitachi Ltd., describes the development of a compact proton therapy system dedicated to discrete spot scanning, synchronized with real-time tumor tracking (RTRT). This innovation directly addresses a critical challenge in radiotherapy: precisely targeting moving tumors, such as those in the lung or liver, while minimizing damage to surrounding healthy tissue. By enabling gated spot scanning—where the proton beam is delivered only when the tumor is in the correct position—Umekawa’s research has improved treatment accuracy and patient outcomes. His work, supported by competitive Japanese funding, has garnered over 16 citations, reflecting its importance in the field of medical physics and radiation oncology. Umekawa’s contributions stand at the intersection of engineering and clinical application, offering a practical pathway toward more effective, non-invasive cancer treatments. His efforts continue to influence the next generation of image-guided and adaptive radiotherapy systems.
