Types of Treatment

Volumetric Modulated Arc Therapy (VMAT)

Volumetric modulated arc therapy (VMAT) delivers a highly precise radiation treatment much faster than other accelerators.  Treatments that once took up to 35 minutes can be accomplished in as little as 2 minutes!  VMAT 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)

Intensity-modulated radiation therapy (IMRT) is a type of radiation therapy in which the intensity of the radiation beam is adapted to match the precise contours of a tumor.  This allows stronger doses to reach the tumor and helps lessen damage to nearby normal tissues.

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

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 by focusing the radiation dose directly 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 inside the body or directly on the treatment site to deliver a high dose of radiation to a small treatment area.  The tissue touching the radioactive material will receive the most radiation while sparing the surrounding healthy tissue.


Genesys Hurley Cancer Institute is excited to announce we are the only cancer center in Michigan to offer AccuBoost!  AccuBoost is new technology that targets radiation doses more precisely than previous techniques while limiting radiation to healthy tissue. [Read More]
