Types of Radiation Therapy

 

Varian Triology Linear Accelerator          
The Varian Trilogy Linear Accelerator is the world's first Image-Guided Radiation Therapy (IGRT) system optimized for both conventional and stereotactic approaches to treating cancer. This cutting-edge equipment precisely targets tumors without affecting surrounding healthy tissues. This permits higher radiation doses and higher cure rates for early-stage cancer patients and supportive therapy with fewer side effects for advanced-stage cancer patients. The Trilogy System shortens daily treatment times and offers greater patient comfort. The Stereotactic Radiosurgery package enables physicians to treat tumors in a short course of only a few days or even in a single session.


BrainLab ExacTrac® X-Ray 6D Image-Guided Radiation Therapy (IGRT) System               
The BrainLab ExacTrac IGRT System is a cutting-edge technology that provides unparalleled capabilities to deliver precisely-targeted radiation therapy. It can pinpoint the exact location of the cancer on a daily basis, correcting for any patient or target motion, allowing high doses of radiation to be delivered while protecting adjacent healthy tissues.
 

Intensity Modulated Radiation Therapy (IMRT)             
IMRT is a treatment technique that uses beams that change shape during the treatment creating many beamlets (beam segments) to vary the radiation intensity across each beam. Thus, allowing us to precisely conform the dose to the target while sparing the nearby normal tissues.  Consequently, tumors that could be treated using conventional techniques can now be treated in much higher doses, resulting in improved cure rates while reducing side effects. IMRT also enables the treatment of hard-to-get-to tumors that were considered untreatable using conventional techniques.
 

Varian RapidArc® Radiotherapy Technology                   
This technology is an effective cancer treatment representing an advanced new form of image-guided IMRT. This technology enables clinicians to program a linear accelerator to deliver precise forms of IMRT up to eight times faster than other IMRT systems. It does this by delivering the complete IMRT treatment to the patient in fewer rotations than traditional IMRT. As a result, the tumor will receive the full radiation dose within less than two minutes compared with 10 minutes or longer for conventional IMRT. Treatment speed is important because it reduces the time that the patient must lie still and avoid any movement. As treatment time is reduced, Varian RapidArc® has the potential to improve the patient's quality of care and comfort.
 

High Dose Rate Brachytherapy (HDR)                 
Patients may benefit from High Dose Rate Brachytherapy, a treatment that allows for the temporary implantation of a high dose radioactive source. This results in shorter duration of treatment time. Our center utilizes the MammoSite, Contura and SAVI technique for the treatment of breast cancer using HDR. 
 

Three-Dimensional Conformal Radiation Therapy (3-D CRT)               
3-D CRT is an image-based computerized treatment planning and delivery technique that utilizes the beam's eye view (BEV) to shape the radiation fields to conform the dose to the target. The planning is performed using ADAC Pinnacle³ treatment planning systems that employ sophisticated three-dimensional dose calculation algorithms to determine the dose given to the patient.


PET/CT Simulation and Three-Dimensional Reconstruction
This treatment process utilizes CT imaging to simulate the radiation treatment. All the necessary images and parameters for the treatment planning process are obtained during the simulation.
 

Electron Beam Therapy              
This is a form of radiation treatment using electrons to treat specific cancers or lesions. Because electrons penetrate only millimeters under the surface of the skin, this is a very useful treatment for skin cancers.
