Types of Treatment

Volumetric Modulated Arc Therapy (VMAT)

delivers a highly precise treatment much faster than other accelerators. Treatments that once took up to 35 minutes sometimes can be accomplished in as little as a single rotation of the machine around the patient in about two minutes! Volumetric arc therapy rotates 360 degrees around the patient, enabling the very small beams with varying intensity to be aimed at the tumor from multiple angles.

Intensity-Modulated Radiation Therapy (IMRT)

is similar to 3D-CRT, but it changes the strength of some beams in certain areas, so that certain parts of the tumor receive stronger doses, while lessening damage to nearby normal body tissues.

Three-Dimensional Conformal Radiation Therapy (3D-CRT)

delivers radiation beams from different directions to match the shape of the tumor. This helps reduce radiation damage to normal tissues and better destroys the cancer by focusing the radiation dose on the tumor.


Brachytherapy is a type of radiation therapy that is given inside the body or close to the surface. The physician will use radioactive material directly inside the body or next to the treatment site for delivering a higher dose of radiation to a smaller area and in a shorter time than is possible with external beam radiation treatment. The tissues surrounding the radiation material receive the most radiation while sparing healthy tissue at a distance away.


In addition to two linear accelerators, we also offer AccuBoost as a treatment option. Genesys Hurley Cancer Institute is excited to announce we are the only cancer center in Michigan to offer this new technology that targets radiation doses even more precisely than previous techniques while further limiting radiation to healthy tissue.
