The UC Davis Comprehensive Cancer Center has unveiled its new Radixact linear accelerator, enhancing radiation therapy to improve outcomes for cancer patients. The Radixact system is the first of its kind in the region, offering more accurate and efficient radiation treatment by using CT imaging to shape beams to each patient's unique tumor characteristics.

Why it matters

The new Radixact system represents a major advancement in radiation oncology, allowing clinicians to deliver radiation therapy with greater precision and reduced risk of damage to healthy tissue. This can lead to better treatment outcomes and fewer side effects for cancer patients in the Sacramento region and surrounding areas.

The details

The Radixact system uses a continuous 360-degree radiation delivery pattern and real-time imaging to adapt the treatment to changes in a patient's anatomy during the course of therapy. This enables clinicians to more accurately target tumors while avoiding healthy tissue. The new system supports a wide range of cancer types, including brain, head and neck, lung, prostate, and gynecological cancers.

  • The Radixact system became fully operational at the UC Davis Comprehensive Cancer Center in February 2026.
  • Construction on the new radiation oncology treatment suite began in May 2025.
