Enhanced Acoustically Transparent Window for Intraluminal Ultrasound Imaging Devices

The present disclosure relates to a novel, improved acoustically transparent window for intraluminal ultrasound imaging devices, offering enhanced imaging resolution, reduced reflections, and real-time feedback capabilities.

The original patent, 'Acoustically transparent window for intraluminal ultrasound imaging device', has limitations in terms of imaging resolution and signal-to-noise ratio. The new inventive concept addresses these limitations by introducing novel materials, designs, and system integrations to improve the overall performance of the intraluminal ultrasound imaging device.

The new inventive concept comprises an acoustically transparent window integrated with an ultrasound imaging assembly, featuring a novel, spiral-patterned acoustic impedance matching layer to reduce reflections and improve signal-to-noise ratio. Additionally, the window can be integrated with a machine learning-based processing system to provide real-time feedback on imaging quality and suggest adjustments to the imaging parameters. Furthermore, the flexible elongate member can be equipped with an integrated, piezoelectric-based acoustic sensor array to detect changes in acoustic impedance and adjust the imaging frequency accordingly. The nanostructured acoustic window coating reduces acoustic reflections and improves imaging resolution at higher frequencies.

The new claims introduce novel materials, designs, and system integrations that improve the overall performance of the intraluminal ultrasound imaging device. The spiral-patterned acoustic impedance matching layer, machine learning-based processing system, piezoelectric-based acoustic sensor array, and nanostructured acoustic window coating are non-obvious and novel compared to the original patent.

Alternative embodiments of the inventive concept may include variations in the spiral pattern, different materials for the acoustic impedance matching layer, or alternative machine learning algorithms for real-time feedback. Additionally, the inventive concept can be adapted for use in other medical imaging applications, such as intravascular ultrasound or endoscopic ultrasound.

The enhanced acoustically transparent window has significant commercial potential in the medical imaging industry, particularly in the fields of intraluminal ultrasound imaging, cardiovascular disease diagnosis, and minimally invasive procedures. The target market includes medical device manufacturers, hospitals, and research institutions.
