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. 11,857,361.

Summary of the Inventive Concept

This inventive concept introduces significant enhancements to the original acoustically transparent window for intraluminal ultrasound imaging devices, enabling improved image resolution, faster scanning, and increased patient safety.

Background and Problem Solved

The original patent disclosed an acoustically transparent window for intraluminal ultrasound imaging devices, which, despite its innovative approach, had limitations in terms of image quality, scanning speed, and patient safety. The new inventive concept addresses these limitations by introducing a tunable acoustic impedance window, an integrated acoustic lens, a nanostructured surface, a real-time feedback mechanism, and an integrated temperature sensor.

Detailed Description of the Inventive Concept

The advanced acoustically transparent window comprises a tunable acoustic impedance material, allowing for real-time adjustments based on the patient's body lumen characteristics. Additionally, an integrated acoustic lens enhances the ultrasound signal quality, while a nanostructured surface improves image resolution. The window is designed to operate with a real-time feedback mechanism, enabling the ultrasound imaging device to adjust its operating frequency accordingly. Furthermore, an integrated temperature sensor allows for temperature-based frequency adjustments, ensuring optimal performance and patient safety.

Novelty and Inventive Step

The new inventive concept's tunable acoustic impedance window, integrated acoustic lens, nanostructured surface, real-time feedback mechanism, and integrated temperature sensor provide a significant improvement over the original patent, offering enhanced image quality, faster scanning, and increased patient safety.

Alternative Embodiments and Variations

Alternative embodiments of the advanced acoustically transparent window may include the use of different materials for the tunable acoustic impedance, varying nanostructured surface patterns, or the integration of additional sensors for real-time monitoring. Variations of the inventive concept could also include the application of the advanced window in other medical imaging modalities or non-medical fields.

Potential Commercial Applications and Market

The advanced acoustically transparent window has significant commercial potential in the medical imaging industry, particularly in the field of intraluminal ultrasound imaging. The enhanced image quality, faster scanning, and increased patient safety offered by this inventive concept could lead to increased adoption and market share in the medical imaging market.
