Enhanced Gantry Rotation for Multimodal Nuclear Medicine Tomography

A novel approach to nuclear medicine tomography, enabling simultaneous data acquisition in both SPECT and PET modes, with optimized gantry rotation and detector design for improved image quality, reduced imaging time, and increased system efficiency.

The original patent disclosed a gantry rotation method for nuclear medicine tomography, but it had limitations in terms of imaging flexibility, system efficiency, and image quality. The new inventive concept addresses these limitations by introducing a modular detector design, continuous gantry rotation, and optimized control systems, resulting in a more efficient and flexible multimodal imaging system.

The enhanced gantry rotation system comprises a rotatable gantry around a subject support axis, enabling simultaneous data acquisition in both SPECT and PET modes. The system features interchangeable detector heads optimized for different imaging modes, allowing for seamless mode switching. The detector carrier is designed for continuous rotation during scanning, reducing imaging time and increasing system efficiency. A dual-mode tomography system with a single detector capable of operating in both SPECT and PET modes increases imaging flexibility and reduces costs. The gantry rotation control system optimizes gantry rotation speed and angle of acceptance for improved image quality and reduced imaging time.

The new claims introduce a novel combination of modular detector design, continuous gantry rotation, and optimized control systems, which provide a non-obvious solution to the limitations of the original patent. The simultaneous data acquisition in both SPECT and PET modes, enabled by the rotatable gantry, is a key inventive step.

Alternative embodiments of the inventive concept could include different detector head designs, adjustable gantry rotation speeds, and varying control system algorithms. Variations of the system could be implemented for specific imaging applications, such as cardiac or neurological imaging.

The enhanced gantry rotation system has significant commercial potential in the nuclear medicine imaging market, particularly in hospitals and research institutions. The system's flexibility, efficiency, and image quality improvements could lead to increased adoption and market share in the multimodal imaging segment.
