Streustrahlung in der Ultraschall-Computertomographie zur Verifizierung der Echtheit von Perlen
- This paper describes a new analysis method developed to distinguish real from fake pearls using non-ionizing, non-destructive ultrasound computed tomography (USCT): In the USCT Shepp-Logan-filtered time-of-flight image, a fake pearl shows irregular, asymmetric scattering of ultrasound, whereas the pattern in a natural pearl is regular and symmetric. We strongly assume that pattern recognitionThis paper describes a new analysis method developed to distinguish real from fake pearls using non-ionizing, non-destructive ultrasound computed tomography (USCT): In the USCT Shepp-Logan-filtered time-of-flight image, a fake pearl shows irregular, asymmetric scattering of ultrasound, whereas the pattern in a natural pearl is regular and symmetric. We strongly assume that pattern recognition of the scattering of ultrasound cannot only play an important role in verifying pearls, but also in testing other materials and tissues in (bio-)medical engineering. Furthermore, and most importantly, this new approach could be helpful for a variety of clinical diagnoses using high-resolution 3D-USCT, such as the detection of X-ray-negative micro-calcifications in early breast cancer. Moreover looking at scattering patterns in dedicated positron emission tomography systems may promote new developments in nuclear medicine diagnostics.…
