Established in 1917, RAS offers an advanced array of diagnostic imaging, interventional radiology and nuclear medicine imaging technologies as well as radiation therapy through a network of facilities in the greater Sacramento region. We have 23 locations throughout Auburn, Cameron Park, Carmichael, Folsom, Roseville, Sacramento and Vacaville.

RAS is accredited by the Accreditation Association for Ambulatory Health Care, which develops standards for patient safety and quality of care. RAS regards its certificate of accreditation as confirmation that our medical practice demonstrates a commitment to high-quality care.

We’ve designed this Web site to help our patients learn about the procedures we perform, to help them prepare for examinations and treatments, and to introduce them to our staff of distinguished medical professionals. This site also contains a section to guide referring physicians in accessing online services.
