Problems
- The current focal region is too large for some applications of focused ultrasound.
- Reducing the focal region will increase resolution, which is always desired.
- There is a trade-off between penetration depth and spatial resolution, caused by the frequency choice.
- Expensive and complex phased array systems with many ultrasound elements are required to overcome trade-offs and increase focusing.
Why NovusTX Devices?
- Our patented multiaxial driving transducers can achieve 3D beam steering.
- The multiaxial transducers allow increasing the degree of focusing without sacrificing penetration depth.
- We can significantly reduce the number of ultrasound elements required in a phased array system to achieve equivalent or superior focusing.
- We can also control the transmitting efficiency when using multiaxial driving.
