This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,356.

Summary of the Inventive Concept

The present invention improves medical imaging by providing a system and method for real-time control and synchronization of manual contrast administration with data-acquisition scans, ensuring accurate and efficient image capture.

Background and Problem Solved

The original patent (PCT/EP2015/052484) relates to a method and device for recording medical images, but it lacks real-time synchronization and control of manual contrast administration, which can lead to inaccurate or incomplete imaging data. The present invention addresses this limitation by introducing a novel system and method that ensures accurate and efficient image capture.

Detailed Description of the Inventive Concept

The enhanced medical imaging system comprises a data-acquisition unit, a signaling unit, and a synchronization module. The data-acquisition unit performs a data-acquisition scan, while the signaling unit outputs a signal for starting and/or stopping manual contrast administration relative in time to the data-acquisition scan. The synchronization module synchronizes the manual contrast administration with the data-acquisition scan and adjusts the timing based on the patient's physiological response. Additionally, the system may include a safety module to detect potential adverse reactions and a tracking module to provide real-time feedback to the operator.

Novelty and Inventive Step

The present invention's novelty lies in the real-time synchronization and control of manual contrast administration with data-acquisition scans, ensuring accurate and efficient image capture. The inventive step is the introduction of a synchronization module that adjusts the timing of manual contrast administration based on the patient's physiological response.

Alternative Embodiments and Variations

Alternative embodiments may include varying the type of imaging modality, incorporating additional sensors to monitor patient response, or using machine learning algorithms to optimize the synchronization process. Variations may also include adapting the system for use in different medical imaging applications, such as cardiovascular or neurological imaging.

Potential Commercial Applications and Market

The enhanced medical imaging system has significant commercial potential in the medical imaging industry, particularly in hospitals and imaging centers. The system's ability to ensure accurate and efficient image capture can improve patient outcomes, reduce costs, and increase productivity.
