Next-Generation Multi-Modality Imaging System
Legal Citation
Summary of the Inventive Concept
A novel multi-modality imaging system integrating SPECT, PET, and MRI capabilities, enabling simultaneous scans and advanced image reconstruction, revolutionizing medical diagnosis and treatment planning.
Background and Problem Solved
The original patent's SPECT system, although innovative, has limitations in terms of imaging capabilities and data acquisition. The new inventive concept addresses these limitations by introducing a multi-modality system that combines the strengths of SPECT, PET, and MRI, allowing for more accurate and comprehensive diagnoses.
Detailed Description of the Inventive Concept
The next-generation multi-modality imaging system consists of a single-photon emission computed tomography (SPECT) module, a positron emission tomography (PET) module, and a magnetic resonance imaging (MRI) module, all sharing a common collimator with multi-pinholes equipped with filters. This design enables simultaneous SPECT, PET, and MRI scans, which are then reconstructed using a machine learning-based algorithm to generate a fused image of the subject. The system's advanced capabilities facilitate more accurate diagnoses, improved treatment planning, and enhanced patient care.
Novelty and Inventive Step
The new claims introduce a paradigm shift in medical imaging by integrating three modalities into a single system, allowing for simultaneous scans and advanced image reconstruction. This represents a significant departure from the original patent's SPECT-only system, demonstrating a novel and non-obvious inventive step.
Alternative Embodiments and Variations
Alternative embodiments of the multi-modality imaging system could include variations in the collimator design, filter materials, and machine learning algorithms used for image reconstruction. Additionally, the system could be adapted for use in different medical specialties, such as cardiology or oncology.
Potential Commercial Applications and Market
The next-generation multi-modality imaging system has vast commercial potential in the medical imaging industry, with potential applications in hospitals, research institutions, and pharmaceutical companies. The system's advanced capabilities and improved diagnostic accuracy could lead to increased adoption and market share, particularly in the growing fields of personalized medicine and precision healthcare.
