Varian Medical Systems has received Food and Drug Administration 510(k) clearance for a new dose calculation algorithm based on AAA techniques. The algorithm improves radiation dose distributions in heterogeneous areas of the body such as the lung, where bone, dense soft tissues, and air pockets each interact with radiation in unique ways, Varian said.
The AAA algorithm is used in the Palo Alto, CA-based vendor's Eclipse 3D radiotherapy treatment-planning software, which also offers the electron Monte Carlo algorithm for planning radiotherapy treatments, Varian said.
