Dynamic tomography
WebJun 14, 2024 · Dynamic tomography has become an important technique to study fluid flow processes in porous media. The use of laboratory X-ray tomography instruments is, however, limited by their low X-ray brilliance. The prolonged exposure times, in turn, greatly limit temporal resolution. We have developed a tom … WebMar 12, 2024 · Dynamic real-time cine magnetic resonance imaging in a patient with lung cancer and suspected myocardial invasion on computed tomography clearly identifies unrestricted sliding motion of the left ventricle while the pericardium demonstrates restricted motion and adherence to the lung cancer.

WebApr 1, 2015 · The concept of “dynamic thermal tomography” (DTT) was suggested in the 1980s. At that time, there was a wave of interest in the tomographic analysis of materials … WebDynamic topography is the reason why the geoid is high over regions of low-density mantle. If the mantle were static, these low-density regions would be geoid lows. However, these low-density regions move upwards in a mobile, convecting mantle, elevating density interfaces such as the core-mantle boundary , 440 and 670 kilometer discontinuities ...
