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. 11,857,370.

Summary of the Inventive Concept

A novel, AI-powered ultrasound system that integrates MRI, IoT, and blockchain technologies to enhance cancer detection, tracking, and treatment.

Background and Problem Solved

The original patent addressed the limitations of MRI-guided biopsy by proposing a method for visually assisting an operator of an ultrasound system. However, the patent did not leverage advanced technologies to further improve the accuracy and efficiency of the biopsy process. The new inventive concept tackles this limitation by combining the original patented method with AI, IoT, blockchain, and other cutting-edge technologies to create a more powerful and effective system for cancer detection and tracking.

Detailed Description of the Inventive Concept

The Synergistic Ultrasound System consists of a machine learning module that predicts regions of interest in anatomical regions, a display module that displays fused images of the predicted regions with other anatomical regions, and an IoT sensor module that provides real-time feedback to the operator. The system also utilizes blockchain technology to securely store and share integrated imaging data. Additionally, the system can generate 3D models of regions of interest and track targets in ultrasound images using AI and blockchain, respectively. This integrated system enables more accurate and efficient cancer detection, tracking, and treatment.

Novelty and Inventive Step

The new claims introduce the novel combination of AI, IoT, blockchain, and ultrasound technologies, which provides a synergistic effect that enhances the accuracy and efficiency of cancer detection and tracking. The inventive step lies in the integration of these distinct technologies to create a more powerful and effective system that overcomes the limitations of the original patented method.

Alternative Embodiments and Variations

Alternative embodiments of the Synergistic Ultrasound System could include the use of other advanced technologies, such as augmented reality or robotic-assisted surgery. Variations of the system could be designed for specific types of cancer or anatomical regions, or could be adapted for use in different medical specialties.

Potential Commercial Applications and Market

The Synergistic Ultrasound System has significant commercial potential in the medical device and healthcare industries, particularly in the areas of cancer diagnosis and treatment. The system could be marketed to hospitals, clinics, and medical research institutions, and could potentially be used in conjunction with other medical imaging technologies to create a comprehensive diagnostic platform.
