Doctors Hospital is one of a small number of hospitals in the US to earn accreditation in radiation oncology by the American College of Radiology (ACR). Radiation oncology is the careful use of high-energy radiation to treat cancer. A radiation oncologist may use radiation to cure cancer or to relieve a cancer patient's pain.

The ACR is the nation's oldest and most widely accepted radiation oncology accrediting body, with over 500 accredited sites. The ACR seal of accreditation represents the highest level of quality and patient safety. It is awarded only to facilities meeting specific Practice Guidelines and Technical Standards. Patient care and treatment, patient safety, personnel qualifications, adequacy of facility equipment, quality control procedures, and quality assurance programs are assessed.
