Eclipse is a compete treatment planning system that simplifies modern radiation therapy planning for various kinds of treatment, including 3D conformal, intensity-modulated radiation therapy (IMRT), electron, proton, and brachytherapy. With the functionality in Eclipse, dosimetrists, physicists, and physicians can efficiently create, select, and verify the best treatment plans for their patients.  In addition to ensuring high standards of care and effective protocols, Eclipse provides clinicians with the flexibility to quickly tailor plans for each patient.  Designed to meet the needs of modern clinics and evolving technologies, Eclipse supports advanced processes such as Image-Guided Radiation Therapy (IGRT) and Dynamic Adaptive Radiation Therapy (DART).
