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. 11,857,803.

Summary of the Inventive Concept

A novel radiation therapy system that integrates real-time tumor response monitoring, machine learning algorithms, and multi-modal imaging data to dynamically adjust radiation intensity and spectrum, ensuring optimal tumor destruction while minimizing healthy tissue damage.

Background and Problem Solved

The original patent disclosed an interstitial source for diffusing alpha-emitter radiation therapy with enhanced beta treatment. However, this approach has limitations in terms of personalized treatment, real-time adaptation, and optimal radiation protocol selection. The new inventive concept addresses these limitations by introducing a system that can dynamically adjust radiation intensity and spectrum based on real-time tumor response monitoring, enabling more effective and personalized radiation therapy.

Detailed Description of the Inventive Concept

The Personalized Adaptive Radiation Therapy System consists of a radiation source configured to emit alpha radiation and beta radiation, a controller that dynamically adjusts the radiation intensity and spectrum, and a real-time tumor response monitoring system. The system utilizes machine learning algorithms and multi-modal imaging data to optimize tumor destruction while minimizing healthy tissue damage. The radiation source can be modified in real-time to optimize radiation protocols, and the system can predict radiation therapy outcomes using a combination of machine learning algorithms, genomic data, and multi-modal imaging data.

Novelty and Inventive Step

The new inventive concept introduces a paradigm shift in radiation therapy by integrating real-time tumor response monitoring, machine learning algorithms, and multi-modal imaging data to dynamically adjust radiation intensity and spectrum. This approach is novel and non-obvious compared to the original patent, which focused on a static interstitial source with fixed radiation intensity and spectrum.

Alternative Embodiments and Variations

Alternative embodiments of the Personalized Adaptive Radiation Therapy System could include the use of miniaturized radiation sources, robotic systems for precise placement and retraction of the sources, and feedback loops that adjust radiation intensity and spectrum based on real-time monitoring of patient vital signs and tumor response. Other variations could include the integration of genomic data, artificial intelligence, and advanced imaging modalities to further personalize and optimize radiation therapy.

Potential Commercial Applications and Market

The Personalized Adaptive Radiation Therapy System has significant commercial potential in the radiation oncology market, with potential applications in treating various types of cancer. The system's ability to provide personalized and adaptive radiation therapy could lead to improved treatment outcomes, reduced side effects, and increased patient quality of life.
