This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,354.

Summary of the Inventive Concept

A novel angiographic examination system that integrates AI, IoT, blockchain, and new materials to provide enhanced image quality, improved medical instrument tracking, and secure data management, enabling more accurate and efficient vascular interventions.

Background and Problem Solved

The original angiographic examination method (U.S. Pat. No. 7,500,784 B2) has limitations in terms of image quality, instrument tracking, and data security. The new inventive concept addresses these limitations by combining the original method with distinct technologies to create a more powerful and efficient system.

Detailed Description of the Inventive Concept

The synergistic angiographic examination system consists of a C-arm X-ray system, an AI-powered image processing module, a blockchain-based data storage system, an IoT-enabled cloud server, a machine learning-based image segmentation module, and a new material-based stent graft. The AI-powered image processing module enhances X-ray images, while the blockchain-based data storage system securely stores and manages patient medical records and imaging data. The IoT-enabled cloud server enables remote processing and analysis of imaging data, and the machine learning-based image segmentation module automates vascular system segmentation from X-ray images. The new material-based stent graft is designed for improved biocompatibility and durability.

Novelty and Inventive Step

The new claims introduce a synergistic combination of AI, IoT, blockchain, and new materials, which is not obvious from the original patent. The integration of these technologies provides a novel and non-obvious solution for angiographic examination, offering improved image quality, instrument tracking, and data security.

Alternative Embodiments and Variations

Alternative embodiments of the synergistic angiographic examination system could include the use of different AI algorithms, IoT protocols, or blockchain architectures. Variations could also include the integration of additional technologies, such as robotics or virtual reality, to further enhance the system's capabilities.

Potential Commercial Applications and Market

The synergistic angiographic examination system has significant commercial potential in the medical imaging and interventional cardiology markets. It could be used in hospitals, clinics, and research institutions, and could also be integrated into telemedicine platforms for remote consultations and procedures.
