maximizing the benefits and minimizing the risks of treatment delivery to the patient. Prism software leverages existing investments in scanners and treatment systems to optimize planning workflow. Prism makes the power of functional magnetic resonance imaging (fMRI), diffusion tensor imaging (DTI) and advanced physiological sequences practical in the treatment planning process. With Prism, treatment plans based on fMRI and DTI studies deliver treatment that is faster, safer and more effective for the patient. Pre-treatment mapping identifies functional structures to avoid during treatment, enabling physicians to deliver treatment that reduces the risk of post-treatment complications. Prism helps establish critical spatial relationships between the patient's anatomical and functional structures in relation to the physiology and pathology of the patient's condition. This allows the physician to avoid damaging valuable tissue during the course of treatment.
