SPECT-CT Fusion Unit for Soft Organ Lesion Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical imaging technologies, such as CT and SPECT, face challenges in providing accurate treatment planning for soft organ diseases due to insufficient anatomical and functional information, with SPECT images lacking detailed structural information and low resolution, making it difficult to combine anatomical and functional data effectively for precise treatment planning.
Innovation Solution
A system and method that integrates functional and anatomical information from SPECT and CT images using a segmentation unit, geometry transformation unit, fusion unit, and treatment planning unit to generate a combined image for accurate segmentation and treatment planning of soft organs, such as the liver, by mapping and combining CT and SPECT images to enhance lesion segmentation and treatment planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If SPECT imaging is used to obtain functional information, then metabolic measurement capability is improved, but anatomical structural detail and image resolution deteriorate
Solution Approach 1:
The patent combines SPECT and CT imaging modalities into a unified SPECT-CT system that simultaneously acquires both functional and anatomical information. The functional SPECT data and anatomical CT data are merged into a single integrated dataset, allowing both metabolic measurement and high-resolution structural visualization without the trade-offs of using either modality alone.
2Measurement precision
If CT imaging is used to obtain anatomical information, then structural detail is improved, but functional metabolic information is lost
Solution Approach 1:
The SPECT-CT system merges anatomical CT imaging with functional SPECT imaging, ensuring that high-resolution structural details are preserved while simultaneously capturing metabolic activity data. This combination eliminates the information loss inherent in using CT alone.
3Ease of operation
If SPECT and CT images are overlaid for cross-referencing, then ease of operation is improved, but segmentation accuracy and treatment planning precision deteriorate
Solution Approach 1:
The patent introduces a dedicated fusion unit that acts as an intermediary between SPECT and CT image processing. This fusion unit performs sophisticated image registration and fusion algorithms that go beyond simple overlay, creating a unified fused image that preserves segmentation accuracy while maintaining ease of cross-referencing. The fusion unit mediates the integration process to achieve both operational simplicity and precision.
