There are many ways to deliver and target radiation into the body.  As with other modalities, radiation delivery techniques give the physician more choices as to how best to treat and target the cancer.  Depending on the type of cancer and stage, one or more methods may be used to maximize tumor reduction and minimize damage to normal healthy tissues. Below is a summary of treatment services we provide. For additional information about these technologies or treatments, please contact us.


The TomoTherapy Hi·Art System® combines a very sophisticated form of intensity-modulated radiotherapy (IMRT) and CT image-guided patient positioning into one integrated system.  Photon radiation is produced by a linear accelerator (Linac) inside the machine that is rotates around the patient 360 degrees. The linac moves in association with a device called a multi-leaf collimator, a computer-controlled set of interlaced leaves that dynamically contours the shape of the radiation beam while the patient is slowly advanced via the treatment table through the center of the machine.(more info)

3-D Conformal Radiation Therapy

3-Dimensional Conformal Therapy allows us to shape the radiation beam around the tumor thereby limiting exposure to normal healthy tissues.  3-D Conformal Therapy involves the use of Computer Tomography (CT) images to construct a 3-D computer-generated re-creation of the internal organs and the tumor. This allows the radiation oncologist to target the treatment area while minimizing side effects.

Intensity Modulated Radiation Therapy (IMRT)

Intensity Modulated Radiation Therapy (IMRT) involves the use of multiple high-energy x-ray beams to target the tumor. The radiation beams are calculated in advance as part of a patient specific treatment plan to deliver precise radiation while minimizing the dose to the normal surrounding tissues. The strength of the beams can be adjusted as necessary depending on the size, location and stage of the cancer.

Image Guided Radiation Therapy (IGRT)

Image Guided Radiation Therapy (IGRT) is a radiation treatment supported by enhanced graphic targeting. By targeting the treatment area using 2 and 3-D imagery, we can achieve better patient outcomes with fewer side effects.  This is particularly useful when addressing prostate, breast, lung, spine, head/neck cancers and other sites in the body.  The clinician can retarget the treatment area daily to, not only to overcome any movement of internal organs, but also to adjust for the change in size and shape of the cancer.

Computer Tomography (CT) Scanning & Simulation

Computer Tomography (CT) Scanning is used to map the organs and structures within the body.  When a treatment plan is developed, a CT Simulation is necessary to acquire measurements and other technical data.  The patient is positioned on the CT scanner table where multiple scans are performed to generate a digital 3-D reconstruction of the tumor area.  The information collected during simulation helps the radiation oncologist and other staff prepare and deliver the radiation.
