Process tomography (PT) is a leading technique for multiphase flow measurement and flow monitoring systems in various fields. PT has the advantage of interpreting acquired measurement data and transforming it into visual tomographic images. The most common method of image reconstruction uses the linear back projection algorithm which often results in blurry images. This paper proposes an enhancement of the reconstructed images using an edge detection image processing technique to convolve with the original image. This filtering technique calculates approximation changes of the horizontal and vertical image derivatives, thus further enhancing image accuracy. Several ultrasonic tomography images were put into a simulation test to validate it. Hence, the image results are being assessed for its performance.

“…The tomography system designer is faced with a major architectural decision in choosing between hard-field and soft-field modalities. Hard-field sensing methods refer to the sensing contribution to the actual measurements only depends on the process medium inside the volume defined by the source and detector [3,56]. The simplest example is X-ray tomography, where the measurements based on the straight-line path through the subject, such as the measurements will not influenced by the environment outside the subject volume.…”

This paper presented a survey on wireless based industrial tomography system, and to review design challenges in the field of embedded wireless solutions. Focuses are on presenting recent researches in wireless based industrial tomography system, and providing the wireless protocols supported by the current embedded technologies. We also explain the influences of wireless characteristics such as RF spectrum usage, Link budget, RF agility, antenna and power consumptions in the performance of the designed wireless system. In this paper, we intend to introduce a set of practical considerations for embedded wireless tomography system design.
