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. 11,857,317.

Summary of the Inventive Concept

A real-time, intraoperative tissue classification and surgical margin assessment system that leverages advanced hyperspectral imaging, machine learning, and multi-modal imaging capabilities to revolutionize surgical guidance and decision-making.

Background and Problem Solved

The original patent's hyperspectral fluorescence and reflectance imaging technology, while innovative, has limitations in terms of speed, resolution, and adaptability. The new inventive concept addresses these limitations by introducing real-time, adaptive, and multi-modal imaging capabilities that enable more accurate and effective surgical guidance.

Detailed Description of the Inventive Concept

The new inventive concept comprises a hyperspectral imaging device capable of resolving wavelengths into more than 100 discrete wavelength bands, a machine learning module for processing said hyperspectral data to generate a probability map of tissue types and margin assessment, and an adaptive imaging system that adjusts its wavelength resolution and range in response to changing tissue conditions and surgical goals. The system integrates with real-time surgical navigation and guidance systems, enabling surgeons to make more informed decisions during procedures. Additionally, the system can incorporate patient-specific hyperspectral imaging data into personalized, 3D-printed surgical models, providing a more accurate and effective surgical planning tool.

Novelty and Inventive Step

The new claims introduce a paradigm shift in hyperspectral imaging for surgical guidance, moving from a static, model-based approach to a real-time, adaptive, and multi-modal imaging system that leverages machine learning and advanced data analytics. The inventive step lies in the integration of these components to enable real-time tissue classification and surgical margin assessment, which is not anticipated by the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different machine learning algorithms, the integration of additional imaging modalities, such as optical coherence tomography, or the development of handheld or robotic-assisted hyperspectral imaging devices. Variations of the system could also be tailored to specific surgical applications, such as neurosurgery or oncology.

Potential Commercial Applications and Market

The next-generation hyperspectral imaging system has significant commercial potential in the surgical guidance and medical imaging markets, with potential applications in a wide range of surgical specialties and procedures. The system's ability to provide real-time, accurate tissue classification and margin assessment could improve surgical outcomes, reduce complications, and enhance patient safety, making it an attractive solution for hospitals, clinics, and medical device manufacturers.
