Varian Launches Velocity 4.0 Cancer Imaging Software With SIRT Dosimetry Analysis
April 11, 2018—Varian Medical Systems, Inc. announced the launch of a new version of its Velocity cancer imaging software, which includes Rapidsphere, a module for yttrium-90 (Y-90) selective internal radiation therapy (SIRT) dosimetry analysis. Velocity 4.0 and the Rapidsphere module have received US Food and Drug Administration 510(k) clearance.
According to the company, Rapidsphere provides the ability for cancer care teams to better understand tumor response and normal tissue toxicity for individual patients receiving SIRT. This new software module extends Varian's Velocity software to interventional radiologists for use in targeted cancer therapy delivery to patients with liver malignancies.
Rapidsphere runs on the Velocity software platform, which aggregates unstructured treatment and imaging data from diverse systems to show a comprehensive view of a patient's diagnostic imaging and treatment history. Rapidsphere is an integrated image-guided dosimetry system for calculating the absorbed dose using posttreatment emission tomography imaging from Y-90 SIRT.
Varian stated that additional new features of Velocity 4.0 include:
- Velocity M3i multimodality motion imaging, which provides simultaneous display and contouring of up to 10 imaging studies (CT, MR, positron emission tomography, single-photon emission CT, ultrasound/, four-dimensional CT, cone-beam CT) with deformable image registration
- Velocity Aria Sync, which provides automatic synchronization of approved objects from Aria and Eclipse and one-click save of Velocity data with Aria and Eclipse
- Velocity Tumor and Dose Tracking, which provides image-based tumor and radiotherapy dose tracking across multiple treatment courses and therapy modalities to verify both volumetric tumor change and the cumulative dose history for cancer patients
