| Tv(Abstract)F |
Katsuyuki Taguchi: Recently energy-sensitive photon counting x-ray detectors (PCDs) have been developed which can be operational under intense x-ray flux used in clinical CT. PCD-based CT is one of the hottest topics in the x-ray CT community and expected to not only improve the current CT images but also enable novel applications such as molecular CT. During todayfs talk, we will review the status of PCDs and the algorithms we have been developing for PCD-CT. Kenji Amaya: Inverse problems are one of the practical topics in engineering where unknown information is determined from external observations. The field of Inverse problems is an interdisciplinary and integrated research area. For example, X-ray CT, a well-known technology that uses inverse analysis, is based on engineering, medical science, mathematics and computer science. In this talk I will provide an introduction to inverse problems, as well as outline some of our recent results in this area such as on-line quality inspection of camera module, estimation of pressure and temperature in air bag, estimation of pressure distribution on brake pad and corrosion detection system of seaside structures. |
