Technology and Treatments

At the Mount Sinai Hospital, we merge the most advanced technology with some of the most experienced professionals in the field to offer state-of-the-art treatment options using a total of five external-beam radiation therapy treatment machines and two simulators. We have the most up-to-date linear accelerators, including Varian TrueBeam systems with three-dimensional on-board imaging.

The following technologies are available for our patients:

  • 3D conformal radiation therapy (3D CRT): 3D CRT is a method of treating patients who have tumors that are too close to vital organs and other structures for normal radiation therapy. Using this technique, highly focused radiation beams maximize the radiation of tumors, while minimizing damage to normal tissue in adjacent organs.

  • Brachytherapy: This type of radiation involves the implantation of radiation devices adjacent to or within a tumor, maximizing the preservation of healthy tissue. This approach is highly effective and commonly used to treat prostate cancer and gynecological malignancies.

  • Image-guided radiotherapy (IGRT): IGRT is one of the most advanced forms for radiation therapy; this treatment is guided by imaging, such as CT scan or X-rays.

  • Intensity modulated radiotherapy (IMRT): IMRT is a state-of-the-art treatment that allows the radiation oncology to deliver a high dose of radiation to a concentrated region of the body by using 3D technology, implemented my special equipment and a sophisticated computer system.

  • Intracoronary brachytherapy: Intracoronary brachytherapy is a highly effective technique, which prevents in-stent restenosis in patients undergoing cardiac catheterization and stent placement for coronary artery disease.
  • Proton Beam Therapy (PBT): Whereas other forms of radiation therapy use x-rays to kill cancer cells, proton beam therapy (PBT) uses particles called protons, which are easier to aim directly at a tumor, thus largely sparing healthy tissue. This sophisticated form of therapy is often used to target cancers located in close proximity to vital parts of the body, and can be combined with conventional photon treatments. Mount Sinai also offers a delivery technique called pencil beam proton therapy, which “sweeps” protons across the treatment area, thus maintaining conformity, eliminating an exit dose and reducing the dose to normal tissues.

  • Stereotactic radiotherapy/radiosurgery (SRS): SRS is a non-invasive method of delivering a single, high-dose of radiation to a tumor. It is principally used to treat cancers of the brain and spinal cord.

  • Superficial Radiotherapy (SRT) - Superficial Radiotherapy (SRT) is a low-energy radiotherapy that penetrates a short distance below the skin's surface. It is a painless and effective alternative to surgery in selected cancers, such as non-melanoma skin cancers found on the surface of the skin. It is especially suitable for instances where surgery could lead to a less than desirable cosmetic outcome (nose, eyelids, lips, ears) or for patients who are too high-risk for surgical procedures. Our SRT-100(™) machine offers the newest and most advanced SRT technology, and is currently the only machine of its kind available in Manhattan. See Patient Stories for an example of a patient who was successfully treated with SRT.
