Legal Citation
Summary of the Inventive Concept
An improved system and method for observing objects containing a bolus of at least one fluorophore, enhancing the accuracy and efficiency of fluorophore concentration mapping through advanced image processing techniques.
Background and Problem Solved
The original patent disclosed a method and device for observing objects containing a bolus of at least one fluorophore. However, the method was limited by the need for iterative processing, weight thresholding, and manual selection of component signals. The new inventive concept addresses these limitations by incorporating advanced image processing techniques, including noise reduction, machine learning-based decomposition, real-time image registration, and spatial filtering.
Detailed Description of the Inventive Concept
The enhanced system comprises a multi-spectral camera, an illumination system, and a processing unit. The processing unit applies a noise reduction algorithm to the input frames prior to decomposition into component signals. The decomposition is performed using a machine learning-based algorithm, which enables more accurate and efficient separation of the component signals. Additionally, the processing unit applies a real-time image registration algorithm to align the input frames, ensuring accurate spatial registration. Furthermore, a spatial filtering algorithm is applied to enhance the visibility of the fluorophore. The system generates a fluorophore concentration map based on the decomposed component signals, providing a more accurate and detailed representation of the fluorophore distribution.
Novelty and Inventive Step
The new inventive concept introduces several novel and non-obvious features, including the application of noise reduction, machine learning-based decomposition, real-time image registration, and spatial filtering algorithms. These advancements provide a significant improvement over the original patent, enabling faster, more accurate, and more efficient fluorophore concentration mapping.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of different machine learning algorithms, such as deep learning-based approaches, or the incorporation of additional image processing techniques, such as edge detection or feature extraction. Variations of the system could also include the use of different types of cameras, illumination systems, or processing units.
Potential Commercial Applications and Market
The enhanced fluorophore observation system has significant commercial potential in the medical imaging and diagnostics industry, particularly in neurosurgery and cancer research. The system's ability to provide more accurate and detailed fluorophore concentration maps could lead to improved treatment outcomes and reduced healthcare costs.
