Honeycomb Ultrasound Breast Patch for Deep Tissue Scanning and Imaging

Technology 

The cUSBr-Patch consists of a honeycomb structure with multiple cells, each containing a window and magnetic attachment means. A tracker with a sensor can be systematically moved between these cells to scan different areas along the patch. The sensor, which may be an ultrasound sensor, blood oxygen sensor, heart rate sensor, or other type, is positioned in the window of each cell. The tracker can rotate the sensor 360 degrees at each position, allowing for multi-angle imaging. The patch is designed to conform to the shape of the body, ensuring consistent contact and accurate measurements. 

Problem Addressed 

This technology addresses several issues with conventional ultrasound imaging, such as poor skin contact, operator dependency, and imaging artifacts (features in an image that are not present in reality). Traditional handheld and automated ultrasound systems require strong compression and struggle with maintaining consistent contact and positioning, leading to variable image quality. The cUSBr-Patch overcomes these challenges by providing a scaffold for stable, repeatable scanning, ensuring consistent contact and positioning.  The honeycomb structure and the tracker system allow for precise sensor placement and movement, reducing imaging artifacts and improving the overall quality of the images. This design enhances patient comfort and reduces the dependency on operator skill, making it a more reliable option for breast screening. 

Advantages 

• Reduces reliance on the skill of the operator in sensor positioning and compression 
• Allows for comprehensive scanning with controlled sensor rotation for multi-angle imaging 
• Conforms to the body, reducing the need for strong compression 
• Can be used with various sensor types and shapes for different measurements 
• Reduces imaging artifacts and improves contact quality 
• The ability to move the tracker between cells allows for multi-angle image reconstruction
