- Pre-clinical imaging using animal or other experimental models
- Clinical diagnoses
Abstract
USC researchers have developed a high-resolution volumetric imaging system capable of producing realtime in-vivo datasets of macro-scalar tissue structures. The device is fabricated using a 3D printer and consists of a 1.75D array utilizing a novel, high frequency pitch-changing interposer backing that maps from a 70 µm x 150 µm transducer element grid to a 150 µm x 150 µm ASIC assembly grid to facilitate access to the 2D array of elements.
Benefit
- Improves on prior-art imaging methods
- Operates at fine resolution
- Produces real-time in vivo images
Market Application
High-frequency arrays (above 10 MHz) offer promising clinical applications in ophthalmology, breast cancer, and skin cancer diagnosis. The adoption of a 1.75D array architecture improves elevation focus and contrast resolution. However, challenges arise with routing bottlenecks due to the tight pitch of elements in the azimuthal and elevational directions. Overcoming these challenges is crucial for unlocking the full potential of subdivided elevation elements, ensuring superior imaging quality and reduced artifacts.
