Our radiation oncologists work with clinical physicists to bring the latest technological developments from industry to our patients.

Proton Therapy

As one of the first hospitals in the world to establish its own proton therapy system, Mass General has an unmatched history in treating both benign and malignant tumors with proton therapy.

Clark Center for Radiation Oncology

The goal of radiation therapy is to eradicate or shrink the tumor cells without damaging the surrounding tissue.

Treatment Procedures

Intensity modulated radiation therapy (IMRT)
A type of conformal radiation which shapes the radiation beam to approximately the shape of the tumor. IMRT enables a more precise conformal radiation dose distribution to the target area by allowing the physician to control the intensity of the radiation beam within a given area.

Volumetric Arc Therapy (VMAT)
An IMRT radiation technique, which can achieve highly conformal dose distributions with improved target volume coverage and sparing of normal tissues compared in one or two gantry arcs which results in reduced treatment time.

Stereotactic radiation surgery and fractionated stereotactic therapy
Precise delivery of radiation to a brain tumor while sparing normal surrounding brain tissue. This technique achieves a higher dose than what could be given with conventional techniques.

Intra-operative radiation therapy
A treatment technique which delivers a large, precise dose of radiation directly into the tumor bed during surgery.

High dose rate brachytherapy
Procedure where doctors place a very high energy radiation source inside your body near the tumor site for a brief period of time. Healthy exposure to normal surrounding tissue can be minimized.

Image guided therapy
High quality, pre-treatment imaging to pinpoint the tumor site and verify correct patient positioning.

PBI (Partial Breast Irradiation)
Breast sparing procedure that delivers external beam radiation twice a day for five days following lumpectomy surgery. This technique offers a significant time saving compared to the whole breast irradiation protocol which requires five to seven weeks of radiation therapy. Treatment with this technique includes a critical selection process by the treatment team.

4-D Computed Tomography (CT) Scan
Adds another dimension (time) to the traditional CT scan used to plan radiation treatment. This method allows radiation therapists to precisely target therapy to moving organs such as the lungs.

Respiratory Gating
A technique that synchronizes radiation to a tumor’s movement, sparing healthy tissue by stopping or "gating" the beam when the tumor moves out of treatment range.

Total Body Radiation Therapy
A radiation treatment technique which is generally delivered as part of the preparation for a bone marrow transplant.

Surface Imaging
A special 3D imaging technique used to verify patient alignment before treatment, as well as track positioning in real time during treatment. This technology uses cameras that detect the patient's skin surface and computes it into a 3D image. It is often used to track deep inspiration breath holds during certain breast cancer treatments.

Pencil Beam Scanning Proton Therapy
A proton treatment technique which allows even more precise shaping of the beam's range and dosage to a three-dimensional target area.
