Intensity Modulated Radiation Therapy
Most Advanced Radiation Medicine
IMRT is the world’s most advanced radiation medicine and is having a profound impact on the way cancers are treated.
IMRT has sophisticated software & hardware.
Lexington Medical Center new and very powerful high-resolution radiotherapy system, Intensity Modulated Radiotherapy (IMRT), combines sophisticated software and hardware that:
- Assigns varying degrees of radiation to the tumor and normal structures
- Creates dose intensity patterns
- Is more flexible and more cost effective than other radiotherapy
- Radiation dose targeting
- Treats multiple targets simultaneously while sparing nearby healthy organs
Minimal Exposure & Complications
With this highly advanced technology, clinicians can escalate the dose of cancer-killing irradiation to tumors with minimal exposure and complications to surrounding healthy tissue.
The radiation dose reflects the volume of the tumor.
Unlike other curative radiation treatments, the new IMRT treatment can define the exact shape of the tumor in three dimensions and vary the radiation dose across the tumor volume to meet the requirements of thickness and the rules set by the Radiation Oncologist.
Inverse Planning Faster & More Accurate
The technology defines the anatomy and dosage goals with input from the Medical Center's CT and MRI units. The system software then analyzes those factors and helps modify or refine the plan. This procedure is called inverse planning. The computer goes through thousands of possible combinations to achieve the treatment plan which best meets the requirements set down by the Radiation Oncologist. This is significantly faster and more accurate than conventional methods of planning.
IGRT - Image Guided Radiotherapy
The newest modality is called IGRT, image-guided radiotherapy. The upgraded linear accelerator is capable of obtaining high-quality images or even CT scans, enabling the radiation team to see the tumor volume before and during each treatment.
Adjustments can be made.
Adjustments in the patient's position can be made to compensate for millimeter changes in organ motion, resulting from voluntary or involuntary causes. This greatly adds to the accuracy of IMRT and Respiratory Gating, which monitors and corrects for patient motion due to breathing.
A Fully-Integrated System
A fully integrated system literally handles the entire treatment process from patient registration to imaging, to treatment planning.
