Description:
Project ID: TECH-2025-34
Background:
Despite that there are many companies that develop POCUS devices, many have so many problems with good images, short battery life, heating issues and no 3D images. Traditionally, a one-dimensional (1D) array transducer is used for two-dimensional (2D) imaging, where the transducer and its cable are heavy and bulky, and only a single slice of an image of the heart can be acquired at each transducer position. Although a 2D array transducer can be used to acquire three-dimensional (3D) images, it is heavier and bulkier. Considering the importance of accuracy within medical diagnostic tools, there is a pressing need for novel technologies to improve imaging systems, but also for other needs of medical ultrasound imaging. This invention provides such tools that are high-quality at a low cost.
Invention Description:
Researchers at the University of Toledo developed a method to use electromagnets or micro step motors with attached or embedded encoders to vibrate a reflector to steer an ultrasound Bessel or focused beam in multiple directions to form a three-dimensional (3D) or multi-plane two-dimensional (2D) images for wearable or point-of-care applications. The new approach will solve the quality of ultrasound and the focus variation in quality by using a Bessel or focused beam and the new configuration will resolve the other issues of being bulky, heavy, fast heating, and it will allow long life for battery in addition to low weight. The approach will additionally allow capturing changes of diseases that may be missed with current ultrasound imaging systems or procedures.
Applications:
- Novel approach for producing real-time 3D Imaging in handheld point-of-care ultrasound and wearable stress echocardiography devices.
Advantages:
- Real-time Wearable or point-of-care 3D or multi-plane 2D imaging
- Battery operated
- Wi-Fi capable
- Smart phone and computer compatible
- Simple way to produce Bessel beam and increase image depth of field
- Simplified imaging system without compromising image quality
- Much lower cost than any 3D or multi-plane 2D imaging systems in the
IP Status: Patent Pending
