Michigan's First CyberKnife® Radiosurgery Center

In 2007, SJMHS unveiled the first CyberKnife® in Michigan. CyberKnife® represents the latest generation of radiosurgery systems, combining image guidance technology with a compact linear accelerator. It has the flexibility to move in three dimensions to focus on the targeted area for treatment, practically anywhere in the body.

One of the Country's Few Brachytherapy Suites

SJMHS has one of few dedicated brachytherapy surgical suites in North America, offering high-dose-rate (HDR) and low-dose-rate (LDR) brachytherapy treatments for prostate, gynecologic, head and neck cancer and breast cancer (mammosite).

Brachytherapy has been an effective treatment modality for the treatment of cancer used for many years.  High Dose Rate (HDR) brachytherapy has specific treatment applications for breast cancers and uterine cancers (endometrial and cervical).

Intensity-Modulated Radiation Therapy (IMRT)

A specialized form of radiotherapy that allows treatment to be more exactly shaped to fit a patient's tumor, sparing normal healthy tissue and lowering the chance of side effects.

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.

IGRT involves radiation treatments guided by CT or X-ray imaging (Cone beam CT or KV matching). During IGRT treatments, doctors compare images daily, just prior to the treatment to see if the treatment needs to be adjusted. This increases the accuracy of very complex treatments. IGRT and CBCT are used in conjunction with IMRT and 3-D conformal treatments. In some cases, doctors will implant a tiny marker in or near the tumor to pinpoint it for IGRT.

CT Planning System

The Brilliance Big Bore CT with a 85 cm opening enables you to scan patients with positioning devices and other apparatus without compromising image quality of positioning. It also provides visualization of multiple lung phases giving the physician the tools necessary t o assess organ motion and define the tumor volumes in a more precise 4-D treatment. The Big Bore CT in combination with the Pinnacle radiation therapy planning system merges multiple images with other imaging technology (i.e. PET and MRI) to achieve the most advance and precise targeted radiation treatment plan.

Linear Accelerators (External Beam Radiation)

SJMHS has five linear accelerators with the most advanced technology capable of delivering stereotactic radiosurgery, IMRT, IGRT and 3D / 4D Gating. SJMHS has one of the nation's leading CCOP's designated by the NCI. This partnership allows access to Radiation Therapy Oncology Group (RTOG) protocols and other NCI sponsored cooperative groups to provide the latest treatments for our patients.
