Introduction

Padmavathi Sundaram is a notable inventor based in Palo Alto, California. He has made significant contributions to the field of medical imaging, particularly in the detection of polyps. With a total of 2 patents, his work has the potential to enhance diagnostic procedures in healthcare.

Latest Patents

One of his latest patents is titled "Polyp detection using smoothed shape operators." This invention improves surface feature recognition in CT images by extracting a triangulated mesh representation of the surface of interest. The shape operators are computed at each vertex of the mesh from finite differences of vertex normals. These operators are then smoothed through an iterative weighted averaging procedure. Principal curvatures at each vertex are calculated from the smoothed shape operators, allowing for the identification of maxima and minima. Vertices marked with the same feature type are clustered together to provide candidate patches, with feature scores computed for each patch.

Another significant patent is "Polyp identification through subtraction of models of medical images." This method involves creating a 3-dimensional model of a medical image that includes both polyps and folds. A second model is constructed to filter out polyps while preserving folds. By subtracting the second model from the first, polyps can be easily identified without interference from folds. This innovative approach streamlines the identification process, making it quicker and more efficient.
