  • Stereotactic body radiotherapy (SBRT)
  • Stereotactic radiosurgery (SRS)
  • Intensity modulated radiotherapy (IMRT)
  • Image Guided Radiotherapy (IGRT)
  • Volumetric modulated arc therapy (VMAT)
  • 3D conformal radiotherapy (3D-CRT)
  • Deep Inspiration Breath Hold (DIBH) and Respiratory Gating using Optical Surface Monitoring System (OSMS) and Real-Time Position Management systems
  • 4-dimensional CT simulation
  • High dose rate brachytherapy (HDR), including image-guided brachytherapy
  • Electron beam therapy
  • Radioisotope therapy

Varian Edge®

Varian Edge

As part of Good Samaritan Hospital Medical Center’s ongoing commitment to clinical excellence, The Varian Edge Radiosurgery Suite represents the most advanced radiosurgery technology available.  The Edge Radiosurgery System offers sub-millimeter pinpoint accuracy featuring a 6-degree of freedom robotic couch combined with extra-fine 2.5 mm high definition multileaf collimators leaves for beam shaping.  Good Samaritan is one of only two centers on Long Island to offer this cutting-edge technology.  Stereotactic radiosurgery allows physicians to precisely target tumor cells while delivering high doses in a small number of treatments.  The Varian Edge Radiosurgery System is a precise, efficient and integrated non-invasive cancer treatment modality designed to deliver high precision radiation treatment.   

Varian TrueBeam®

Varian TrueBeam

Good Samaritan was the first hospital in Suffolk County to implement the state-of-the-art Varian Truebeam in 2014.  The Varian Truebeam is an advanced medical linear accelerator that is fully integrated for image-guided radiotherapy to treat targets with enhanced speed and accuracy.  Truebeam offers cancer patients faster, shorter and more precise treatments while monitoring and compensating for tumor motion. This technology treats cancer anywhere in the body where radiation therapy is indicated.

HyperArc High-Definition Radiotherapy

Multiple brain metastases are now frequently treated with stereotactic radiosurgery instead of whole brain radiation therapy.  Good Samaritan Hospital Medical Center is the first center on Long Island to adopt HyperArc High Definition Radiotherapy.  This new technology allows for fully automated robotic treatment delivery to safely, accurately and comfortably treat multiple brain tumors. 

RapidPlan Knowledge-Based Planning

Good Samaritan Hospital Medical Center has been at the forefront of high quality radiation planning for many years.  RapidPlan Knowledge-Based Planning offers machine learning capabilities to further improve treatment plan quality and consistency.   


AlignRT is a system that tracks a patient’s position before and during radiation therapy to improve treatment accuracy. Using 3-dimensional stereo camera units, AlignRT tracks the skin surface in real time to compare the current location to ideal position with submillimeter accuracy. AlignRT has been shown to facilitate Deep Inspiration Breath Hold (DIBH) to reduce heart dosage for patients with left breast cancer.  AlignRT is also used to precisely perform frameless stereotactic radiosurgery for brain tumors that eliminates the need for invasive head frames.
