Publication number: 20240148252Abstract: A neurosurgery system for probing brain tissue of a patient for tumorous tissue. The system including a suction tool, an excitation source, an optical instrument, and a controller. The suction tool including a suction cannula defining a lumen, an optical fiber configured to transmit fluorescence emitted by the brain tissue; and an indicator configured to selectively emit visible light. An excitation source is configured to emit an excitation light having a wavelength to induce the fluorescence in the tumorous tissue. The optical instrument is coupled to the optical fiber. The optical instrument configured to convert the fluorescence emitted by the brain tissue and transmitted by the optical and configured to determine that the brain tissue is tumorous based on the electrical signal and activate the indicator based on the determination.Type: ApplicationFiled: March 14, 2022Publication date: May 9, 2024Applicant: Stryker European Operations LimitedInventors: Kevin Buckley, Gerard Nunan, Stephen Faul, David Eustace, Kevin Manley, Robert Mitchell Baldwin, David Tallon

Patent number: 8577114Abstract: An apparatus and method for expanding the FOV of a truncated computed tomography (CT) scan. An iterative calculation is performed on the original CT image to produce an estimate of the image. The calculated estimate of the reconstructed image includes the original image center and a estimate of the truncated portion outside the image center. The calculation uses an image mask with the image center as one boundary.Type: GrantFiled: February 20, 2012Date of Patent: November 5, 2013Assignee: Siemens Medical Solutions USA, Inc.Inventors: David Faul, Christian J. Michel
