Legal Citation
Summary of the Inventive Concept
A paradigm-shifting ultrasound guidance system that integrates real-time MRI-ultrasound fusion, machine learning-based lesion detection, and advanced tracking and registration capabilities to revolutionize targeted biopsy and interventions.
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, this approach still relied on manual registration and lacked real-time feedback. The new inventive concept solves these limitations by introducing a next-generation system that combines real-time MRI-ultrasound fusion, automated probe tracking, and personalized diagnosis capabilities, enabling more accurate and efficient targeted interventions.
Detailed Description of the Inventive Concept
The new inventive concept comprises a real-time MRI-ultrasound fusion module, a machine learning-based lesion detection module, and a user interface displaying a 3D visualization of the fused MRI and ultrasound images. The system also includes automated ultrasound probe tracking using deep learning-based algorithms and real-time registration capabilities. Additionally, the system enables personalized prostate cancer diagnosis using generative adversarial networks and convolutional neural networks. The wearable sensor-based adaptive ultrasound imaging capability further enhances image quality and operator experience.
Novelty and Inventive Step
The new claims introduce a novel fusion of real-time MRI-ultrasound fusion, machine learning-based lesion detection, and advanced tracking and registration capabilities, which are not obvious from the original patent. The integration of these components enables a paradigm shift in ultrasound-guided interventions, providing a more accurate, efficient, and personalized approach to targeted biopsy and diagnosis.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of different machine learning algorithms, various sensor arrays for probe tracking, or different registration algorithms. Additionally, the system could be adapted for use in other anatomical regions or medical applications, such as cardiovascular or neurological interventions.
Potential Commercial Applications and Market
The next-generation ultrasound guidance system has significant commercial potential in the medical device industry, particularly in the fields of urology, radiology, and interventional oncology. The system's ability to improve accuracy, efficiency, and patient outcomes could lead to widespread adoption in hospitals and clinics, generating significant revenue and market share.
