Advanced Multi-Frequency Harmonic Acoustography System for Enhanced Target Tissue Identification and Border Detection

This inventive concept presents a novel, high-performance multi-frequency harmonic acoustography system that significantly improves target tissue identification and border detection capabilities. The system integrates advanced technologies, including dynamically adjustable frequency differences, dual-mode transducers, real-time signal processing, adaptive filtering, and compact probe designs, to provide high-contrast images, enhanced target tissue characterization, and improved portability.

The original patent, 'Multi-frequency harmonic acoustography for target identification and border detection,' introduced a method for performing multi-frequency harmonic acoustography for target tissue identification and border detection within a target tissue. However, the original patent's limitations include fixed frequency differences, limited transducer capabilities, and lack of real-time signal processing. The new inventive concept addresses these limitations by introducing advanced features that significantly enhance the system's performance, usability, and versatility.

The advanced multi-frequency harmonic acoustography system comprises a focused confocal transducer with a dynamically adjustable frequency difference Δf, allowing for real-time optimization of target tissue identification and border detection. The system also features a dual-mode transducer capable of switching between high-frequency and low-frequency operation, enhancing target tissue characterization. A real-time signal processing module provides instantaneous feedback on target tissue properties during imaging, while an adaptive filtering technique suppresses background noise and enhances target tissue visibility. The system's compact, handheld probe design ensures enhanced portability and ease of use in clinical settings.

The new inventive concept's novelty lies in its integration of advanced features, including dynamically adjustable frequency differences, dual-mode transducers, real-time signal processing, adaptive filtering, and compact probe designs. These features, individually and collectively, provide a significant improvement over the original patent, offering enhanced performance, usability, and versatility.

Alternative embodiments of the advanced multi-frequency harmonic acoustography system could include variations in transducer design, such as using phased arrays or annular arrays, or incorporating additional features like Doppler ultrasound or elastography. The system could also be adapted for use in different clinical settings, such as cardiology or neurology, or integrated with other imaging modalities like MRI or CT.

The advanced multi-frequency harmonic acoustography system has significant commercial potential in the medical imaging industry, particularly in the fields of oncology, cardiology, and neurology. The system's enhanced performance, usability, and versatility make it an attractive solution for clinicians and researchers seeking to improve patient outcomes and advance medical research.
