Meet The Team

The Hoag Radiation Oncology Team consists of many members, some of which our patients become very familiar with on a daily basis, and others who are hard at work behind the scenes.

Our main goal is to provide patients with the best care possible, using the latest technologies, in a safe and proven manner. Hoag’s expert radiation oncology team consists of several very specialized individuals who are specially trained, licensed and/or certified to aide in your care.

Radiation Oncologists

A radiation oncologist is a physician with specific training in radiation oncology. At Hoag, all of our radiation oncologists are board certified by the American Board of Radiology. They meet with patients in consultation to discuss the role of radiation therapy as part of a patient’s treatment plan.

Hoag’s radiation oncologists direct each patient’s radiation course, and work closely with a patient’s medical oncologist, surgical oncologist and other physicians to ensure the best possible outcome.

Although many individuals are involved in the delivery of a patient’s radiation treatment, the radiation oncologist is the “leader” directing each patient’s care. Hoag’s radiation oncologists meet frequently with patients during the course of their treatment to answer questions and meet any needs as they arise.

Medical Physicists

Hoag Family Cancer Institute has four medical physicists dedicated to supporting the Radiation Oncology department. At Hoag, each of our Medical Physicists is board certified by the American Board of Radiology.

The Medical physicist works directly with radiation oncologists and medical dosimetrists in the planning phase of a patient’s treatment. The physicist provides the technical information needed to understand how each of the treatment machines work, how much and what type of radiation they produce, and performs regular quality assurance checks to ensure the safe, accurate delivery of the patient’s treatment.

These highly trained professionals are critical to implementing and maintaining the sophisticated technology of a highly advanced radiation oncology program. In addition, Hoag’s medical physicists meet directly with patients to answer questions regarding the physics of radiation, or the complex equipment used in a patient’s treatment plan.

The following medical physicists are part of the radiation oncology team at Hoag Family Cancer Institute:

  • Ralph Mackintosh, Ph.D., D.A.B.R.
    Dr. Mackintosh is an American Board of Radiology certified Medical Physicist with over 30 years of experience in the field. He obtained his Ph.D. in Radiologic Physics from UCLA and was the chief physicist at several Southern California medical centers before coming to Hoag in 1993. His clinical specialties and research interests include Gamma Knife radiosurgery, high dose-rate brachytherapy (HDR), IMRT and endovascular brachytherapy.
  • Marianne E. Plunkett, M.Sc., D.A.B.R.
    Dr. Plunkett is an American Board of Radiology certified Medical Physicist with over 20 years of experience at several nationally known radiotherapy centers. She received her Masters degree from the University of Kentucky in 1989 and has worked at the Dana Farber Family Cancer Institute in Boston, Harvard Medical School’s Joint Center for Radiation Therapy, and William Beaumont Medical Center in Michigan. Her clinical interests and specialties include Intensity-Modulated Radiation Therapy (IMRT), 3D conformal therapy, image-guided surgery, stereotactic radiotherapy and functional MRI.
  • Annamarie Minion, M.S., D.A.B.R.
    Annamarie is an American Board of Radiology certified Medical Physicist with almost 13 years of experience in Medical Physics. She received her Masters degree from East Carolina University in 1997. Prior to coming to Hoag in 2002, she was a consulting physicist in the Chicago-area and then southern California. Her clinical interests are image-guided intensity-modulated radiation therapy, stereotactic radiation therapy, stereotacticradiosurgery and adaptive radiation therapy.
  • Jinchu Huang, Ph.D., D.A.B.R.
    Dr. Huang is an American Board of Radiology certified Medical Physicist with over 15 years of experience in the field of radiation therapy. He obtained his PhD in physics from New York University (NYU). Before joining Hoag in 2007, he worked as clinical faculty at State University of New York at Stony Brook (SUNYSB), Winthrop University Hospital (WUH), and University of Southern California (USC). His clinical experience and interests include Gamma Knife radiosurgery, IMRT and image-guided radiotherapy.

Medical Dosimetrists

In addition to medical physicists, the physics staff at Hoag Hospital also includes medical dosimetrists – each is certified by the Medical Dosimetrist Certification Board.

Hoag dosimetrists work together with the radiation oncologists and medical physicists to prepare a custom treatment plan designed specifically for each patient. They utilize specialized computer systems and programs with each patient’s image studies to plan the delivery of radiation. The Medical Dosimetrists also work closely with the radiation therapists to ensure that each treatment plan is clearly defined for accurate delivery on a daily basis.

Radiation Oncology Nurses

The Hoag Radiation Oncology nursing staff is composed of registered nurses (RNs) licensed in the state of California. The nursing staff is highly skilled in the field of oncology with a minimum of five years of clinical oncology experience prior to working in Hoag Radiation Oncology. Most are members of the Oncology Nursing Society and are credentialed as Oncology Certified Nurses by this national organization.

Hoag nurses are an integral part of the radiation oncology treatment team and work very closely with the radiation oncologists to manage patient care. They meet with patients weekly to discuss concerns and answer any questions, as well as provide the highest level of patient-centered care.

Radiation Therapists

Our Radiation Therapists are certified by the American Registry of Radiologic Technologists (ARRT), licensed by the state of California (CRT) and are required to comply with continuing education requirements. The radiation therapists administer treatment to the patients on a daily basis. Consequently, they provide the most immediate link to the treatment team. The therapists are caring and compassionate and are focused on the successful outcome of each patient’s treatment plan.
