Varian and GE Medical Systems have combined imaging and radiotherapy to create the EXaCT Targeting Cancer Care system. The new product, shown Nov. 4 to 8 at the annual meeting of the American Society for Therapeutic Radiation and Oncology (ASTRO) in San Francisco, features a GE HiSpeed CT scanner combined with Varian’s Clinac medical linear accelerator.
