Radiation Oncology in Arizona

Meet Our Staff

Led by our physicians, the radiation oncology team includes therapists, nurses, nurse practitioners (NPs), dosimetrists, physicists, and other support staff, all working together to deliver efficient and effective treatments.

Radiation Therapists

A radiation therapist gives the radiation treatments prescribed by the physician. During each treatment, the therapist positions the patient correctly on the treatment machine and directs each radiation beam in turn to the area designated in the plan.

Nurses

A nurse works closely with each radiation oncologist, assisting with patient care and helping address questions and concerns that patients have during treatment.

Nurse Practitioners

Working under the direct supervision of the radiation oncologists, our nurse practitioners assist physicians in the management of patients under treatment and during their subsequent follow-up care.

Dosimetrists

Working under the direction of the radiation oncologists and physicists, a dosimetrist helps plan the details of each patient treatment. Using a computer, the dosimetrist plans the best way to deliver radiation to the target while minimizing the dose to nearby healthy tissues.

Physicists

Physicists measure the radiation beams and provide the data used to plan the treatments. The physicist ensures that the treatment machines are operating safely, accurately, and consistently. Frequently physicists work together with radiation oncologists and dosimetrists to plan and verify special treatments (IOERT, IMRT, 3-D conformal, other) and they participate in research and development of new treatment techniques. Our physicists are all certified by the American Board of Radiology and/or the American Board of Medical Physics in the Physics of Radiation Oncology.
