Blockchain + Radiotherapy: The Scenarios of the 5G‐Enabled Smart Radiotherapy Era

Abstract

In cancer radiotherapy (RT), each step can be digitalized, from CT simulation, planning, dose verification, and image guidance to treatment delivery. Therefore, RT may be the most digitized discipline in the field of internal medicine. Then, questions arise. What potential development opportunities does the development of network transmission technologies, such as blockchain and 5G, provide to promote the progress of tumor RT? What will the future of smart RT (SART) look like? The purpose of this article is to introduce briefly the main characteristics of blockchain and 5G transmission technologies and share ideas to imagine the “tomorrow” of smart RT, hoping to provide a more accurate, safe, and comfortable RT experience for patients in the future.
