Radiation Oncology

A nurse and patient prepare for procedure.

Cutting edge technology is the cornerstone of our radiation oncology department. Utilizing state-of-the-art equipment including two linear accelerators with Multileaf Collimator. We have also just introduced an advanced Image-Guided Radiation Therapy system new to the area. Our board certified radiation oncologists, nurses, radiation therapists, dosimetrist and medical physicist use radiation therapy to treat many different types of cancer.

We work together to provice the most advanced patient care possible. Benefits of our sophisticated equipment include minimizing radiation to the surrounding normal tissues and organs and reduced patient treatment time on the table.

Scheduling and Consultations

We offer treatments on the leading edge of technology including:

CT Scan Simulation

Simulation is used to locate and accurately pinpoint the areas of the body that need radiation. Simulation assures the patient is positioned for each treatment in the exact same manner and that the radiation is being delivered to the precise location of the cancer. The simulation images are used to produce a computerized 3-D model of the actual site of the tumor. Our staff can then study the affected area from all possible angles in order to treat the cancer from the optimal direction, providing the highest possible dose of radiation to the tumor, while maximally sparing the surrounding normal tissue.

3-D Conformal Radiation Therapy

Three-dimensional (3-D) conformal radiation therapy uses computer technology to allow more precise targeting of a tumor with radiation beams using width, height, and depth. A 3-D image of a tumor is obtained using computed tomography simulation. Special computer programs design raditation beams that "conform" to the shape of the tumor. Because the healthy tissue surrounding the tumor is largely spared by this technique, higher doses of radiation may be used to treat the cancer, while maintaining lower levels of toxicity.

Intensity Modulated Radiation Therapy

Intensity modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that utilizes computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor.

The radiation dose is designed to conform to the three-dimensional (3-D) shape of the tumor by modulating or controlling the intensity of the radiation beam to focus a higher radiation dose to the tumor while minimizing radition exposure of surrounding normal tissues.

Combinations of serveral intensity modulated fields from different beam directions produce a customized radiation dose that maximizes tumor dose while minimizing the dose adjacent normal tissues.

Digital Portal Imaging

As conformal techniques progress to full dynamic intensity modulation the assurance of accurate target localization is nearly impossible to achieve by conventional means.

The digital portal imaging system provides high-resolution, high-contrast images, which enable faster verification of portal conformance for assurance of treatment quality. These superb quality images are available within seconds, paving the way for image guided therapy.

Image Guided Radiation Therapy

Image Guided Radiation Therapy (IGRT) requires extremely accurate target localization as margins decrease and dose escalates: steep dose falloff at the field edge is a particular IGRT advantage.

Exact target localization must always be assured. With our IGRT, gold fiducial marker technology is used to provide submillimeter localization accuracy. A pair of digital portal images is acquired daily. The location of the gold markers is identified.

Utilizing a triangulization localization method through a sophisticated software package, the computer automatically calculates the directions and distances required to have the target volume in exactly the same position as was planned and shifts the table automatically to get it there. Thus accounting for internal motion to enhance the level of target localization precision.

High & Low Dose Radiation Brachytherapy

Brachytherapy places a radioactive source inside your body, tightly focused to the site of the cancer. This technique ensures the maximum radiation dose is given where you need it most, while allowing only small amounts of radiation to reach the healthy surrounding tissue. In many cases, brachytherapy is an effective alternative to surgical removal of a tumor and the affected organ.

Brachytherapy treatment at the Springfield Regional Cancer Center is often used for internal cancers of the breast, cervix, uterus, lung and esophagus.

Breast Brachytherapy

The Springfield Regional Cancer Center offers the latest innovations in breast cancer treatment through internal radition procedures called breast brachytherapy. Breast brachytherapy has many distinct advantages including:

  • Radiation can be directly targeted to areas at higher risk from cancer.
  • Since radiation is administered interally, it is less likely to harm healthy tissue surrounding the affected area.
  • Treatment is done on an outpatient basis and is usually completed within a week's time.

MammoSite is for select patients with early stage breast cancer following breast conserving surgery. Utilizing a ballon catheter, which can be inserted into the lumpectomy cavity up to 10 weeks after breast conserving surgery, a radioactive source is placed directly into the cavity.

Delivering partial breast irradiation through the MammoSite appoarch can decrease the number of visits to the radiation department from being daily, Monday-Friday, for 6 1/2 weeks, via external beam, to twice a day visits for one week.

Contura - Multilumen Breast HDR
Contura Breast HDR is a new minimally invasive treatment of delivering internal radiation therapy following a lumpectomy for breast cancer. The Contura method uses a small balloon catheter that fits inside the lumpectomy cavity. A tiny radioactive seed is inserted into the balloon and delivers the radiation.

Therapy with the Contura device is typically preformed over a period of one to five days. Contura patients receive treatment twice a day for five days.

Cone Beam CT

With Cone Beam CT, tumors can be tracked each day before patient treatment so that even the slightest movement within the body will be visualized before treatment is delivered.
