Multi-modality tomography

A Tactile Skin System for Touch Sensing with Ultrasound Tomography

“…Advanced iterative reconstruction algorithms such as Total Variation (TV) regularization are used, which has more potential in the solution of the regularized inverse problem in a fixed manner as described in [18]. Simple image fusion is used as a means of data fusion to combine two forms of transmission images [10], in which the average of the normalized intensities of TOF and AA images.…”

“…We then use the average value of TOF and AA for each imaging pixel for the fusion image. It is the same approach used in [10]. In [10], a triple modality UST system was developed that included the reflection mode UST, while the reflection mode UST can also work for the UST based touch skin.…”

“…It is the same approach used in [10]. In [10], a triple modality UST system was developed that included the reflection mode UST, while the reflection mode UST can also work for the UST based touch skin. In this paper, the focus is on transmission mode UST.…”

“…Transmission mode UST is based on imaging properties such as acoustic attenuation (AA) or time of flight (TOF), which can be used to determine the amplitude and velocity profiles of sound in the region of interest (ROI) through quantitative information. Image fusion uses the results of TOF-UST and AA-UST measurements [10]. In terms of the size of UST based skin, it can be implemented in a large area, in particular the sensitivity in the central area is high.…”
