Latest Patents

Liang's latest patents include a method for rib suppression in X-ray chest images based on a Poisson model. This innovative approach conducts contourlet transformation on the image and utilizes the correlation of transformation coefficients across different scales to enhance texture. By designing a strip-type detection filter according to the Hessian matrix eigenvalue, the method effectively identifies rib locations. The combination of enhanced texture and rib area information allows for the establishment and solution of a rib suppression Poisson model, significantly improving the observation quality of X-ray images.

Another significant patent is a lung lobe contour extraction method aimed at digital radiography (DR). This method involves obtaining a representative lung lobe contour template through offline training and initializing a contour extraction system for chest DR radiography. The process includes three-layer pyramid decomposition of DICOM images, the use of a Gabor filter bank for image reconstruction, and refinement of the resulting black and white image using the Zhan-Suen algorithm. This comprehensive approach results in accurate lung lobe contour shapes, enhancing the diagnostic capabilities of radiologists.
