    In recent years, radiation therapy outcomes have improved significantly because of the ceaseless efforts of healthcare professionals, as well as the new developments and widespread availability of high-precision radiation therapies, which were realized by the increased sophistication of control and computing technologies and the intensive and accurate delivery of radiation beams to the target tumor, while minimizing damage to the surrounding healthy tissue. On the other hand, there has been a growing need for the "more efficient" delivery of high-precision radiation therapies because of the increase in the number of cancer patients waiting for treatment. This report introduces "Vero4DRT," our radiation therapy equipment sold under the "MHI-TM2000 Linear Accelerator System" brand name. Utilizing its unique hardware structure and configuration, this system has made it possible to establish a truly innovative beam delivery method for achieving further improvements in radiation therapy outcomes.
