Publication number: 20230099906Abstract: An image registration method, a computer device, and a non-transitory storage medium. The method includes: acquiring a target moving image and a target reference image to be registered, the target moving image and the target reference image being scanned medical images with the same dimension; and performing a registration process on the target moving image and the target reference image by using a pre-trained image registration model to obtain a target registration parameter. The image registration model is a deep learning model for performing registration process on a moving image and a reference image between which a scan field of view difference is greater than a predetermined difference value. The method can improve registration efficiency.Type: ApplicationFiled: September 25, 2022Publication date: March 30, 2023Inventor: XIN WENG

Publication number: 20140213971Abstract: Neuromodulation assemblies (200) include an extravascular prosthesis (202) disposed around and contacting at least a portion of an exterior surface (204) of a vessel (V) and a radially expandable intravascular prosthesis (206) contacting an interior surface (208) of the vessel. The neuromodulation assemblies are configured to compress, pinch, or squeeze a target nerve within the adventitia of the vessel between the extravascular and intravascular prostheses in order to impinge and disrupt the target nerve, thereby blocking or stopping nerve signal transduction. Neuromodulation assemblies configured in accordance with the present technology may also utilize radio-frequency energy, a drug, and/or magnetic attraction to block nerve signal transduction for neuromodulation thereof.Type: ApplicationFiled: April 26, 2012Publication date: July 31, 2014Inventors: Mark J. Dolan, Lance Ensign, Joseph Berglund, Xin Weng, Lori Garcia, Benjamin J. Clark
