Elekta AB has developed a wide range of products and accessories to enable highly accurate and precise delivery for stereotactic body radiation therapy (SBRT). In this chapter the specific systems designed and manufactured by Elekta will be presented, including their developments for image guidance, multileaf collimation, specialized couchtops, and motion management strategies. Elekta has developed image guidance technology for kilovoltage cone beam CT, ultrasound, and 4D motion management tools. Elekta multileaf collimator (MLC) technology provides modulation for intensity modulated radiation therapy (IMRT) and has recently been improved to provide 4 mm leaves for high conformality SBRT. Elekta couchtops and treatment tables with 6D motion provide for improved patient setup, and a wide range of motion management solutions such as abdominal compression, active breathing coordination, and laser-based positioning systems. These technologies are combined in the latest line of linacs from Elekta, including the Synery-S and Axesse with their dedicated stereotactic radiotherapy (SRT) and SBRT features.
