Varian Trilogy™ Linear Accelerator (LINAC)
The Varian Trilogy™ Linear Accelerator (LINAC) is an advanced radiotherapy system designed to deliver highly precise external beam radiation therapy for the treatment of cancer and selected benign conditions. The platform integrates advanced imaging, treatment planning, and radiation delivery technologies to support personalized treatment while minimizing radiation exposure to surrounding healthy tissues whenever possible.
Advanced Treatment Technologies
The Varian Trilogy™ system supports a comprehensive range of modern radiotherapy techniques, including:
- RapidArc® / Volumetric Modulated Arc Therapy (VMAT)
- Intensity-Modulated Radiation Therapy (IMRT)
- Three-Dimensional Conformal Radiation Therapy (3D-CRT)
- Stereotactic Radiotherapy (SRT)
- Stereotactic Radiosurgery (SRS)
- Electron Beam Therapy
The most appropriate treatment technique is selected individually by the radiation oncology team according to the patient's diagnosis, tumor characteristics, and clinical requirements.
Radiation Delivery System
The system provides multiple photon and electron energy options to support the treatment of various tumor types and anatomical regions. Its 120-leaf High-Definition Multileaf Collimator (HD120 MLC) enables highly conformal radiation beam shaping, supporting accurate and controlled radiation delivery.
Image-Guided Radiotherapy (IGRT)
The Trilogy™ platform incorporates advanced image-guidance technologies that allow patient positioning to be verified immediately before treatment. These technologies include:
- Cone Beam Computed Tomography (CBCT)
- Kilovoltage (kV) imaging
- Megavoltage (MV) imaging
- Electronic Portal Imaging (EPID)
These imaging systems support Image-Guided Radiation Therapy (IGRT) by helping verify accurate patient positioning and treatment alignment during each radiotherapy session.
Simulation and Treatment Planning
Our Radiation Oncology Department utilizes advanced simulation and treatment planning technologies, including:
- Three-dimensional CT simulation
- Siemens Biograph Duo PET/CT simulation for image-guided treatment planning
- Eclipse® three-dimensional treatment planning system for individualized treatment planning
- ARIA® Oncology Information System for integrated patient management, treatment verification, and network connectivity
Together, these technologies enable comprehensive image-based treatment planning and support individualized radiotherapy approaches tailored to each patient's clinical condition.
