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. 11,857,289.

Summary of the Inventive Concept

The inventive concept discloses specialized diffuse optical tomography (DOT) systems adapted for unique operational environments, such as disaster relief, high-security, extreme weather conditions, and high-altitude settings, enabling accurate breast cancer detection and optimized functional imaging in these niche markets.

Background and Problem Solved

The original patent disclosed a system for optimizing functional images of a lesion region using guided diffuse optical tomography. However, the original system had limitations in terms of portability, security, and environmental adaptability. The new inventive concept addresses these limitations by providing specialized DOT systems for specific, narrow markets or unique operational environments.

Detailed Description of the Inventive Concept

The inventive concept comprises a range of DOT systems, each tailored to a specific environment or application. For instance, a portable DOT device is designed for disaster relief settings, allowing for remote or damaged area imaging. A secure DOT device is developed for high-security environments, ensuring the integrity of sensitive information. Weather-resistant DOT devices are created for extreme weather conditions, and high-altitude DOT devices are designed for operation at elevated altitudes. Each system integrates a DOT device with a processing unit, enabling optimized functional imaging in these specialized settings.

Novelty and Inventive Step

The new claims introduce novel adaptations of the original DOT system, including portability, security, and environmental hardening features, which provide a non-obvious solution for breast cancer detection and imaging in unique operational environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include wearable DOT devices for remote monitoring, cloud-based processing units for secure data transmission, or modular DOT systems for easy transportation and assembly in disaster relief settings.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical imaging and healthcare industries, particularly in niche markets such as disaster relief, high-security, and remote or underserved areas. The specialized DOT systems can provide accurate breast cancer detection and optimized functional imaging, improving healthcare outcomes in these unique environments.
