The Elekta Infinity™ clinical linear accelerator (LINAC) is a comprehensive image-guided radiation therapy system that utilizes simultaneous manipulation of gantry position and speed, multileaf collimator, dose rate, and collimator angle for optimization of radiation delivery. It is used in conjunction with a Philips Brilliance Big Bore™ computed tomography (CT) instrument that features an 85 cm bore size for precise imaging of large sample sizes. The LINAC is useful for partial body irradiations.
