Flow imaging using ultrasonic time-resolved transmission mode tomography

Describes an image reconstruction algorithm for ultrasound tomography using time-resolved transmitting mode ultrasound. It is applicable to many ultrasound imaging areas and is particularly suitable for process tomography like multiphase flow imaging. The special feature of this algorithm is that it tests at a specific time the pulse´s arrival instead of attenuation information. This algorithm is developed from a system point of view therefore the data collection is discussed in detail. The system using transmitting mode algorithm substantially reduces the data measurement time compared to the one using reflection mode algorithm. In contrast the former can handle the data measurement with ease. The images reconstructed by this algorithm are encouraging and are ready for further processing if needed
