The Radixact System with TomoTherapy technology is one of the most integrated, advanced systems for comprehensive cancer treatment available today and is routinely used to treat a variety of cancers - from routine to complex tumors, those located in hard-to-reach areas and recurrent tumors.
The Radixact System is a sophisticated radiation therapy system that effectively treats cancer anywhere in the body with high precision. The only radiation therapy system designed on a CT scanner foundation, the Radixact System uses daily imaging to guide the treatment each day and deliver highly accurate radiation dose from 360 degrees around the patient.
The Radixact System provides a non-invasive treatment option that is designed to target tumors anywhere in the body, while significantly reducing common side effects that may occur with older radiation therapy techniques. The unique design of the Radixact System - featuring integrated CT imaging and helical delivery - provides greater control of the radiation dose so it conforms precisely to the tumor and helps minimize dose to healthy tissue.
The helical design of the Radixact System - unique among radiation therapy systems - enables continuous 360-degree radiation dose delivery as the patient table moves. The Radixact System revolves around you while thousands of "beamlets" - more precise than the radiation beams of conventional systems - are delivered to the tumor. Each beamlet can deliver a different dose of radiation. Different doses go to different parts of each tumor, with less damage to surrounding healthy tissue.
Designed on a CT scanner foundation, the Radixact System features fully integrated, daily imaging. This sophisticated imaging technology is seamlessly built into the way your Radixact treatment is delivered, giving your treatment team the ability to clearly see the shape and location of your tumor - anywhere in the body - in real time before each treatment session.
The Radixact System now features Accuray's unique Synchrony real-time motion synchronization technology. It is designed to correct for tumors that move as a result of bodily processes, including respiration and digestion, as well as patient movement. Synchrony is the only technology that uses image guidance during treatment delivery to automatically adapt the movement of the radiation beam in synchronization with the movement of the tumor. The beams of radiation are delivered continuously throughout the treatment session as the patient breathes naturally. In comparison, gating methods deliver radiation only when the tumor is close to the expected location and pause treatment delivery when the moving tumor is outside of the "treatment window." This lengthens the time the patient needs to be on the treatment table.
The Radixact System was designed to revolve around you. The gantry - which holds the radiation source, or the linear accelerator (commonly called a LINAC) - physically revolves around your body during treatment to allow continuous 360-degree delivery of the radiation beams as the treatment table also moves. This not only enhances delivery precision, but largely eliminates the need to stop and reposition the patient during treatment.
The collimator shapes the radiation beam and can modulate one beam into many smaller, narrow beamlets. Each beamlet can deliver a different dose of radiation. Different doses go to different parts of each tumor. The very large number of small, independent dose contributions is the key to the flexibility in creating highly personalized dose distributions. This allows your treatment team to deliver 3D image-guided intensity-modulated radiation therapy (IG-IMRT).
