Profile: Radiation Oncology Services provides radiation therapy for cancer patients. We have obtained the Joint Commission (JC) accreditation. We are equipped with state-of-the-art linear accelerators and computerized treatment planning systems. Each of our centers has a state-of-the-art Varian linear accelerator with multi-leaf collimation and intensity modulated radiation therapy (IMRT). In conjunction with BrainLAB's ExacTrac® system, our Varian linear accelerators are capable of advanced technology known as image-guided radiation therapy (IGRT). We also use Synergy® which is a state-of-the-art digital accelerator equipped with multi-leaf collimation, a wide spectrum of X-ray energies, and both IMRT and IGRT technology. The IGRT technology used by us improves the accuracy in patients treated with external beam radiation therapy whether the patient is treated with 3D conformal therapy or IMRT. Imaging followed by adjusting the patient into perfect position forms the basis of IGRT. Our treatment methods include external beam radiation therapy and brachytherapy.
