NewYork-Presbyterian Brooklyn Methodist Hospital

Radiation Oncology Residency Program

NewYork-Presbyterian Brooklyn Methodist Hospital combines the award-winning expertise of Weill Cornell Medicine physicians, experienced healthcare staff, the intellectual energy of graduate residency and fellowship training programs, and the latest technologies to provide compassionate, culturally sensitive care to Brooklyn’s residents.

The NewYork-Presbyterian Brooklyn Methodist Hospital Radiation Oncology Residency Training Program is fully accredited by the Accreditation Council for Graduate Medical Education (ACGME). We are a community-based program with accreditation from the American College of Radiology We offer four years of post-graduate training in the specialty of radiation oncology following the completion of a year of training in an ACGME-accredited medical, surgical, or transitional-year internship.

Our faculty includes:

  • Radiation oncologist
  • Medical physicists
  • Radiation biologist

The department has:

  • Megavoltage linear accelerators (Varian TrueBeam, Clinac iX)
  • Siemens Somatom large-bore CT simulator
  • Advanced image-guided radiotherapy
    • This includes intensity-modulated radiotherapy, volumetric-modulated arc therapy, and stereotactic radiotherapy

On our premises, we perform:

  • All types of Stereotactic Radiosurgery
  • Stereotactic Body Radiation Therapy (SBRT)
  • Respiratory gated and deep Inspiratory Breath Hold Technique (DIBH) when indicated
  • Contact HDR brachytherapy
  • LDR prostate implants
  • Balloon-based accelerated partial breast irradiation offered to select patients
  • High-dose-rate treatments delivered by a Varian GammaMedPlus Iridium-192 remote afterloader.

We are a main member of the NRG cooperative group (RTOG, NSABP, GOG).

We are also a clinical affiliate of the University of Wisconsin-La Crosse Medical Dosimetry Masters Program and the NewYork-Presbyterian Brooklyn Methodist Hospital School of Radiation Therapy.

Each year, residents are required to take the In-Service Training Examination administered by the American Board of Radiology. This comprehensive exam covers clinical oncology, radiation physics, and radiobiology. It is intended to prepare residents for the written board examinations and evaluate their performance relative to peers at the same level in training.

The exam also helps the program director and residents identify areas where improvement may be needed in basic science or clinical knowledge. The RAPHEX exam is also given annually, specifically to assess physics proficiency.

We participate in the National Resident Matching Program. Applications are accepted through the Electronic Residency Application Service.
