Enhanced Method for Providing Image Data of a Hollow Organ
Legal Citation
Summary of the Inventive Concept
An improved method for generating high-quality image data of a hollow organ, utilizing dual-contrast agents with distinct absorption spectra to enable accurate material separation and representation.
Background and Problem Solved
The original patent disclosed a method for providing image data of a hollow organ using a single contrast agent. However, this approach has limitations in accurately distinguishing between different materials within the organ. The present inventive concept addresses this limitation by introducing a dual-contrast agent approach, enabling more precise material separation and representation.
Detailed Description of the Inventive Concept
The enhanced method involves applying two contrast agents with distinct absorption spectra to the hollow organ. The first contrast agent is applied to the lumen of the organ, while the second contrast agent is applied to the wall of the organ. Spectrally resolved computed tomography (CT) data are then generated based on the absorption spectra of both contrast agents. This approach enables accurate material separation and representation, allowing for a more detailed and precise understanding of the organ's structure and composition.
Novelty and Inventive Step
The use of dual-contrast agents with distinct absorption spectra is a novel and non-obvious improvement over the original patent. This approach enables accurate material separation and representation, which was not possible with the single-contrast agent approach.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept may include varying the type and concentration of contrast agents, adjusting the CT scanner settings, or incorporating additional imaging modalities. These variations can be used to tailor the method to specific clinical applications or to improve its performance.
Potential Commercial Applications and Market
The enhanced method for providing image data of a hollow organ has significant commercial potential in the medical imaging industry. It can be used to improve diagnostic accuracy, enable more effective treatment planning, and enhance patient outcomes. The target market includes hospitals, clinics, and research institutions involved in medical imaging and diagnostics.
