What treatment delivery options are available at our centers -
* 3D or ‘Three-dimensional' treatment is an advanced form of radiation therapy adopted as our gold standard at both facilities it uses CT or CAT scan images to plan, and then deliver tightly focused radiation beams to cancerous tumors. The number and size of radiation beams and the direction from which it is aimed can be customized to give a high radiation dose to the tumor while minimizing the radiation dose of surrounding normal tissues.
* IMRT or ‘Intensity-modulated radiation therapy‘. It is a new form of radiation therapy that uses CT images to plan, and then deliver hundreds of tightly focused radiation beamlets to cancerous tumors. The intensity (or amount) of the radiation is being changed during treatment to give a higher radiation dose to the tumor while minimizing the radiation dose of surrounding normal tissues. An analogy might be like having hundreds of bicycle spokes (radiation beamlets) going through your body, and the area where the spokes all meet is at the area where all the radiation adds together to kill the tumor.
* Image Guided Radiation Therapy (IGRT)
IGRT is at the forefront in radiation cancer treatment. IGRT is the next step above and beyond IMRT combining the benefits of the advanced treatment technology with an increased accuracy. Some tumors (such as the prostate) move from one treatment session to another as a result of normal internal organ action (digestion, elimination, and breathing). In the past, we treated areas larger than the prostate by as much as 1 cm to account for this normal movement and inherent daily setup differences. IGRT provides us with capability to target the prostate with an accuracy to within 0.2 cm.
* Stereotactic Radiosurgery - This treatment has been used as an alternative to brain surgery over the past 30 years allowing very precise delivery of Radiation to treat small abnormalities, tumors or other functional disorders, such as Glioma, Acoustic Neuroma, AVM malformations, Meningioma, and metastatic carcinoma, while sparing the normal brain tissue. The entire treatment is given in a single dose (Radiosurgery). Because a metal frame is fixed to the patient’s head, this type of treatment is the most accurate available
* Brachytherapy - Brachytherapy involves placing radioactive seeds directly into the tumor. Brachytherapy will direct radiation precisely to the immediate area of your tumor, while significantly sparing surrounding normal tissue, and decreasing the risk of unnecessary side effects. We are proud to offer our patients LDR Brachytherapy to treat diseases including female gynecological malignancies and male prostate cancers.
* Superficial X-Rays - Superficial radiotherapy is highly effective in the treatment of certain basal cell and squamous cell carcinomas of the skin. Low energy x-ray radiation is used to kill cancer cells on the skin and takes less than 5 minutes per day. The machine appears similar to an x-ray arm located in a dental office.
