Title: Qian Diao’s Patents in Dental Claims and Periodontal Chart Processing.

Introduction

Qian Diao is an inventor based in San Jose, California, and works at Optum, Inc. His patent work focuses on applying artificial intelligence and image processing to dental claims and periodontal records. He is named on 2 patents.

Latest Patents

Diao’s recent inventions address two related challenges in processing dental information.

“Methods, Systems, and Computer Program Products for Flagging Dental Claims for Further Scrutiny Based on Processing of Dental Clinical Images and Periodontal Charts Using Multiple Artificial Intelligence (AI) Models” describes a system for reviewing dental claims. It analyzes clinical images with multiple AI models to identify procedure codes, and uses optical character recognition to extract periodontal pocket measurements and their positions from chart images. The system compares the submitted claim code with the image-based findings and checks whether the measurements support the code. It flags claims when the submitted code is inconsistent with the images, is not for a visibly detectable procedure, or is unsupported by the periodontal measurements.

“Methods, Systems, and Computer Program Products for Processing a Periodontal Chart to Store the Information Items Therein in a Construct That Preserves the Relationships Between the Information Items” focuses on converting periodontal chart images into structured data. Optical character recognition extracts pocket measurements and their coordinates, while layout rules associate each measurement with the corresponding tooth. The resulting computer-readable format preserves those relationships for later use.
