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. 11,857,364.

Summary of the Inventive Concept

The present inventive concept relates to an improved ultrasound transducer probe with enhanced thermal management and electromagnetic interference (EMI) control, ensuring more efficient and reliable medical imaging.

Background and Problem Solved

The original patent disclosed an ultrasound transducer probe with thermally conductive fins or planar layers. However, the existing design still faces limitations in thermal management and EMI control, which can compromise image quality and probe durability. The new inventive concept addresses these limitations by introducing advanced thermal management systems and EMI control mechanisms.

Detailed Description of the Inventive Concept

The enhanced ultrasound transducer probe features a thermally conductive layer integrated with a return plane to reduce thermal resistance and improve heat dissipation. Additionally, the probe incorporates a Faraday cage with overlapping joints and EMI gaskets to minimize electromagnetic interference. The probe array assembly can be manufactured using 3D printing, enabling enhanced structural integrity and reduced production time. The probe's metal inner shell is overmolded with a transparent plastic cover, providing improved durability and resistance to damage. A thermal management system utilizing a combination of thermally conductive fins and a heat sink minimizes thermal buildup.

Novelty and Inventive Step

The new inventive concept's novelty lies in the integration of advanced thermal management systems and EMI control mechanisms, which provide a significant improvement over the original patent's design. The inventive step resides in the specific combination and implementation of these features, which result in a more efficient, reliable, and durable ultrasound transducer probe.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different thermally conductive materials, varied Faraday cage designs, or alternative manufacturing methods. Additionally, the thermal management system could be adapted for use in other medical imaging applications.

Potential Commercial Applications and Market

The enhanced ultrasound transducer probe has significant commercial potential in the medical imaging industry, particularly in applications requiring high-quality images and reliable probe performance. The target market includes hospitals, clinics, and medical research institutions.
