Radiation therapy firm Nomos has rejected the claims filed by medical technology developer Zmed charging the company with patent infringement for its recently released ImageSync ultrasound real-time imaging and positioning software.
The suit, filed in federal court in Boston, accuses Cranberry Township, PA-based Nomos’ BAT SXi ultrasound-based stereotactic tumor localization device of infringing on U.S. Patent No. 5,447,154, which covers 3-D to 3-D matching technology in Zmed’s SonArray system. Nomos noted that the same court has previously ruled that the Nomos technology does not infringe on the Zmed patent.
The BAT SXi technology in ImageSync correlates anatomical structure and isodose information and displays it in two-dimensional form, according to John Manzetti, president and CEO of Nomos. He said that the product does not reconstruct tumor images in a 3-D rendering, but rather allows the user to visualize, in real time, both anatomy and isodose structures superimposed on an ultrasound image.
