The Radiation On Demand concept evolved in trying to look for convenient and cost-effective ways to treat cancer while achieving the best clinical outcomes. Electron Radiation Therapy has become the mainstay of Cancer Treatment. The research and development of providing Radiation Therapy using Electrons have been the focus of all major Radiation Technology experts. The equipment previously used was a fixed and immobile Linear Accelerator. It was massive, bulky and heavy equipment, generally installed in lead shielded bunkers for protection of radiation scatter and management. The radiation given to patients is given externally, passing through many body parts, such as skin, flesh, muscle, bones, etc., before it reaches the desired tumor bed. Normal tissue is harmed along with the cancerous tissue. ROD’s approach was to eliminate all the above issues. Recently a more state of the art, mobile technology with a manageable footprint was developed. Now the ROD Team can provide Mobile Radiation Therapy by transporting the treatment unit into the operating room where a single dose radiation is given during surgery directly to the tumor bed, while the patient is under anesthesia. Treating the tumor bed rather than the whole body eliminates the undesirable side effects. It’s convenient as the patient does not have to go through up to 35 daily radiation center trips, avoids the anxiety of the long term cancer therapy, is cost-effective, easy, and complete one-day treatment. ROD is the only organization providing Mobile IOeRT Services for best outcomes of patients by bringing the technology to surgeons and hospitals throughout the continental USA.
