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. 11,857,354.

Summary of the Inventive Concept

The inventive concept adapts angiographic examination methods for specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, or extreme weather conditions.

Background and Problem Solved

The original patent relates to an angiographic examination method for depicting a target region inside a patient with a vascular system. However, it lacks consideration for specialized scenarios where standard angiography systems may not be suitable. The present inventive concept addresses this limitation by providing customized solutions for high-security, disaster relief, extreme weather, and other niche environments.

Detailed Description of the Inventive Concept

The inventive concept encompasses a range of specialized angiographic examination systems and methods tailored to specific operational environments. For high-security needs, a secure data storage unit and biometric authentication module ensure sensitive patient information is protected. For disaster relief, a portable and compact angiography system with a communication module enables remote medical experts to receive examination results. In extreme weather conditions, the system is adapted to withstand extreme temperatures and humidity levels. Additionally, the inventive concept includes adaptations for high-altitude environments, compensating for the effects of high altitude on X-ray emission and detection, and for emergency response scenarios, integrating the angiography system with a telemedicine platform and GPS module.

Novelty and Inventive Step

The new claims introduce novel adaptations of the original angiographic examination method, specifically designed for specialized environments. These adaptations provide a non-obvious solution to the limitations of the original patent, offering a unique combination of security, portability, and adaptability features.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include additional features, such as encryption methods for secure data transmission, modular design for easy transportation, or integrated sensors for monitoring environmental conditions. Variations could also include customized systems for other niche environments, such as space exploration or search and rescue operations.

Potential Commercial Applications and Market

The specialized angiographic examination systems and methods have significant commercial potential in various industries, including healthcare, emergency response, and disaster relief. The target market includes hospitals, clinics, and medical research institutions operating in high-security, disaster relief, or extreme weather environments.
