In the patient-centric world of radiation oncology, it is critical that computed tomography (CT) simulation is accessible, repeatable and flexible. To build on these values, Canon Medical Systems USA Inc. is now expanding its offerings for CT simulation in radiation oncology to include the Aquilion Prime SP and Aquilion Lightning 80 premium CT systems. In addition to the Aquilion LB, the Aquilion Prime SP and Aquilion Lightning 80 now include radiation therapy (RT) options that provide high-quality CT imaging and precision tools for oncology planning.
