3D ultrasound imaging has become of tremendous value in obstetrics, gynaecology, radiology, cardiology, and image-guided surgery and therapy. The increasing use of 3D ultrasound has been due to the limitations of 2D viewing of 3D anatomy using conventional ultrasound. However, despite significant advances in 3D imaging techniques, commercially available technology suffers from low resolution, speed issues, and probe heating problems.
Researchers at the University of Alberta have developed a new imaging method, Fast Orthogonal Row-Column Electronic Scanning (FORCES), that is capable of 3D ultrasound imaging with unprecedented image quality. This technology is coupled with novel bias-sensitive top orthogonal to bottom electrode (TOBE) arrays and capacitive micromachined ultrasound transducers (CMUT) to outperform industry alternatives at a much lower cost. These arrays offer 3D imaging without a complex fully-wired array. By using crossed electrode arrays, this technology also avoids any probe heating problems and size limitations that are encountered with current technologies.
- Much lower cost than current industry standards
- Capable of whole-organ 3D imaging
- High image quality, imaging speed, and robustness to motion
The invention represents a valuable opportunity for use in the medical diagnostics and imaging industry.
