Varian Medical Systems has released a new version of its Velocity cancer imaging software that includes Rapidsphere, a module for dosimetry analysis of yttrium-90 (Y-90) selective internal radiation therapy (SIRT).
Rapidsphere allows cancer care teams to understand tumor response and normal-tissue toxicity for individual patients receiving SIRT, Varian said. The module extends Varian's Velocity software to interventional radiologists for use in targeted cancer therapy delivery to patients with liver malignancies.
Rapidsphere uses the Velocity software platform, which aggregates unstructured treatment and imaging data from systems to show a complete view of a patient's diagnostic imaging and treatment history. Rapidsphere calculates the absorbed dose using post-treatment emission tomography imaging from Y-90 SIRT.
Other updates to Velocity 4.0 include Velocity M3i (multimodality motion imaging), which simultaneously displays and contours up to 10 imaging studies with deformable image registration; Velocity Aria Sync, an automatic synchronization of approved objects from Aria and Eclipse and one-click save of Velocity data with Aria and Eclipse; and Velocity tumor and dose tracking to verify both volumetric tumor change and the cumulative dose history for cancer patients.
