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. 11,857,374.

Summary of the Inventive Concept

This inventive concept improves upon the original patent by introducing novel features that enhance the accuracy, speed, and usability of registering live streams of ultrasound images with X-ray images, enabling more effective medical procedures and improved patient outcomes.

Background and Problem Solved

The original patent's limitations include potential inaccuracies in image registration, slow processing times, and operator dependency. This new inventive concept addresses these limitations by incorporating advanced modules for real-time image quality assessment, dynamic beamforming parameter adjustment, automatic segmentation, machine learning-based position prediction, and haptic feedback.

Detailed Description of the Inventive Concept

The enhanced image registration system comprises a real-time image quality assessment module that optimizes image registration accuracy by analyzing the quality of both ultrasound and X-ray images. The system also features a dynamic beamforming parameter adjustment module that improves image registration speed by adapting the ultrasound probe's parameters in real-time. Additionally, an automatic segmentation module isolates the medical device from surrounding tissue in the X-ray image, reducing operator intervention. Machine learning-based algorithms predict the position of the medical device in the X-ray image, further enhancing registration accuracy. Finally, a haptic feedback module provides tactile feedback to the operator during the registration process, improving usability and reducing operator fatigue.

Novelty and Inventive Step

The new claims introduce novel features that are not obvious from the original patent, including the integration of real-time image quality assessment, dynamic beamforming parameter adjustment, automatic segmentation, machine learning-based position prediction, and haptic feedback. These features provide a significant improvement in image registration accuracy, speed, and usability, making the inventive concept non-obvious and innovative.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different image quality assessment algorithms, varying beamforming parameter adjustment strategies, or alternative machine learning-based position prediction methods. Additionally, the haptic feedback module could be replaced with alternative tactile feedback mechanisms or augmented reality visualization tools.

Potential Commercial Applications and Market

The enhanced image registration system has significant commercial potential in the medical imaging industry, particularly in applications such as interventional radiology, cardiology, and oncology. The system's improved accuracy, speed, and usability make it an attractive solution for medical device manufacturers, hospitals, and research institutions.
