“…There is a clear tendency to implement more optimal solutions with an emphasis on active control and optimization [11][12][13][14][15][25][26][27]. There are many numerical methods [1-4, 17, 24, 28, 29], but in order to solve the inverse problem, ultrasound tomography [5][6][7][8][9][10]16] can be used.…”

This article presents the ultrasonic structure for the analysis of technological processes in the field of reflective and transmission waves. Ultrasound tomography enables the analysis of processes occurring in the examined object without interfering with its interior through appropriate acquisition and analysis of data. The design goal is to verify the repeatability of measurement results by eliminating laboratory equipment. The ultrasonic tomograph has been designed in a modular way and consists of a motherboard connected to an analog signal conditioning board, a liquid crystal display with an integrated graphics processor and a high voltage pulser with a 64 channel multiplexer. The solution was designed for tomographic measurements of technological process properties.

“…In such a way we have got much faster imaging software, which is particular important in cases where "on line" imaging is needed. Time profit is particularly high for 3D problems [12][13][14][15][16][17][18].…”

This article presents a new effective imaging method that can be applied in ultrasonic and radio tomography. The proposed method by changing the shape of the voxels leads to a substantial simplification of the algorithm at the cost of small approximations of the voxels. As proved in the work, these approximations do not have a significant impact on the readability of the image which is several times faster. Streszczenie. W pracy przedstawiono nową efektywną metodę obrazowania, która może mieć zastosowanie w transmisyjnej tomografii ultradźwiękowej lub radiowej. Proponowana metoda zmienia kształt voksela z sześciennego na kulisty dzięki czemu uzyskuje się znaczące uproszczenie algorytmu kosztem niewielkiej aproksymacji wokseli. Jak udowodniono w pracy, przyjęta aproksymacja nie ma znaczącego wpływu na wiarygodność obrazów, a jest kilkukrotnie bardziej efektywna. Efektywny algorytm do konstrukcji trójwymiarowych obrazów tomograficznych

Ultrasound tomography provides the ability to analyse processes occurring inside the facility without interfering with the production, analysis and detection of obstacles, defects and various anomalies. The presented measuring system has a specially designed measuring structure (including electrodes, thanks to which it is an innovative solution in the field, particularly effective in the analysis). Knowledge of the characteristics of each tomographic technique solution, the application allows you to choose the appropriate method of image reconstruction. A reverse problem is the process of identifying optimization or synthesis, in which the goal is to determine the parameters describing the data field.Streszczenie. Tomografia ultradźwiękowa daje możliwość analizowania procesów zachodzących wewnątrz obiektu bez zakłócania produkcji, analizy i wykrywania przeszkód, wad i różnych anomalii. Prezentowany układ pomiarowy ma specjalnie zaprojektowaną strukturę pomiarową (w tym elektrody, dzięki czemu jest innowacyjnym rozwiązaniem w terenie, szczególnie skutecznym w analizie). Znajomość charakterystyki każdego rozwiązania techniki tomograficznej, aplikacja pozwala wybrać odpowiednią metodę rekonstrukcji obrazu. Odwrotnym problemem jest proces identyfikacji optymalizacji lub syntezy, w którym celem jest określenie parametrów opisujących pole danych (System pomiarowy tomografii ultradźwiękowej do pozyskiwania i analizy danych.
