1 results about "Virtual endoscopy" patented technology

The application provides a virtual endoscopy imaging method, system, device and medium. The method comprises: acquiring multi-energy level imaging body data of a target object; performing base substance decomposition processing on the multi-energy level imaging body data based on a preset base substance combination to generate base substance images corresponding to each base substance; reconstructing a luminal three-dimensional structure model representing a luminal region of the target object based on the multi-energy level imaging body data; performing lesion detection according to the base substance images and the multi-energy level imaging body data to obtain lesion information and associating the lesion information with the luminal three-dimensional structure model; performing endoscopy in the luminal three-dimensional structure model through a virtual endoscope and generating visualization information of a check region of the virtual endoscope in the check region; wherein the visualization information comprises the check region and / or lesion information in the check region. The application can intuitively observe the lesion position and component information in a dynamic check process.
