Services
Stereotactic Radiosurgery
Stereotactic Radiosurgery delivers high-dose radiation to brain tumors with sub-millimeter precision. This single-day treatment effectively targets metastatic cancers and non-cancerous growths while preserving surrounding healthy tissue. Our advanced linear accelerators enable precise delivery for meningiomas, pituitary adenomas, and arteriovenous malformations.
SpaceOAR Placement
SpaceOAR gel creates temporary separation between the prostate and rectum during radiation therapy. This innovative solution reduces rectal exposure by 50% while maintaining therapeutic prostate doses. Clinical studies show significant reductions in urinary and sexual side effects for prostate cancer patients.
Intensity-Modulated Therapy
IMRT uses computer-controlled linear accelerators to deliver precise radiation doses to prostate tumors. The technology modulates beam intensity to conform to irregular tumor shapes while protecting adjacent bladder and rectal tissue. This approach enables higher curative doses with reduced treatment-related complications.
Stereotactic Body Radiation
SBRT delivers highly focused radiation in 3-5 sessions for lung and prostate tumors. This hypofractionated approach concentrates doses within small treatment volumes while minimizing exposure to healthy tissue. Effective for oligometastatic disease and early-stage cancers.
Image-Guided Therapy
IGRT integrates CT imaging with treatment delivery for daily tumor localization. Our systems automatically adjust patient positioning to account for anatomical changes, ensuring sub-millimeter accuracy. This technology enables smaller treatment margins and reduced radiation exposure to surrounding organs.
