Tittle:
Method and device for time encoding of ultrasonic impulses
Summary:
A German scientist from a university in the North-east of Germany developed a method and a device that reduces the occurrence of faulty ultrasonic images by time encoding, applicable in human medicine as well as material technologies.
Industrial partners are sought for a license agreement or a further development on the basis of research cooperation agreement.
Description:
Ultrasonic imaging is widely used in applications for medical and material inspection. The basic principle is an Impulse-Echo-mechanism in which a sonic wave is generated and then reflected by organic tissue. With constant speed of sound the time between sending and receiving of the signal can be used to determinate a distance. With this information it is now possible to form the different distances of all reflecting surfaces into one ultrasonic scan.

A problem with ultrasonic scans are artifacts which are results of faulty time correlations, the main reasons for faulty resulting images. Furthermore, the depth of signal penetration is determinated by the frequency of impulse repetition. Goal of this innovation is to reduce the occurrence of faulty images by removing artifacts as well as enhancing the signal penetration depth.

The offered method describes a mechanism in which the ultrasonic impulse is time encoded by adding a time signal to the main pulse. By alternating between time encoded and normal impulses it is possible to determinate which of the received signals was send at an even or an uneven cycle. Faulty echo detection is prevented by this method along with the possibility to double the sending frequency which leads to twice the penetration depth.
Additionally, it is possible to encode the ultrasonic impulse further by using amplitude modulation. With this mechanism the received signal is spited into a measurement and an encoded signal. By doing so it is possible to allocate time and volume information to the received signal. Because of this allocation the occurrence of artifacts is further reduced which leads to a higher quality of ultrasonic scans.

This innovation is applicable in various fields, e.g. human medicine and in detection of corrosion/degration of materials.

The scientist wants to find an industrial partner who is interested in a license agreement and/or a further development on the basis of a research cooperation agreement in order to generate a functional model or a prototype to commercialize the innovation.
Advantages and Innovations:
- less faulty scans (higher quality of the scans) by filtering artifacts
- higher signal penetration depth
- better handling of non-vertical reflections as well as signal scattering
