An Investigation of Brightness Changes in Ultrasound Images due to Temperature Variations in Liver Tissue during Radiofrequency Ablation
Introduction: one of the minimally invasive methods of treatmenting liver malignancies is Radiofrequency Ablation (RFA) which can be applied to primary or secondary tumors. Nevertheless, the disease recurrence is probable after RFA application partially due to the inadequate capability of temperature monitoring of the target tissue and visualizing the thermal damage. The goal of this work was t...
متن کاملConsiderations for Modeling Thin Cirrus Effects via Brightness Temperature Differences
Brightness temperature difference (BTD) values are calculated for selected Geostationary Operational Environmental Satellite (GOES-6) channels (3.9, 12.7 pm) and Advanced Very High Resolution Radiometer channels (3.7, 12.0 pm). Daytime and nighttime discrimination of particle size information is possible given the infrared cloud extinction optical depth and the BTD value. BTD values are present...

متن کاملHighest Brightness Temperature Observed in the Universe
Giant radio pulses of the millisecond pulsar B1937+21 were recorded with the S2 VLBI system at 1.65 GHz with NASA/JPL’s 70-m radio telescope at Tidbinbilla, Australia. These pulses have been observed as strong as 65 000 Jy with widths ≤ 15 ns, corresponding to a brightness temperature Tb ≥ 5 · 10 39 K, the highest observed in the universe. The vast majority of these pulses occur in a 5.8 μs and...
متن کاملMathematical modeling of collagen turnover in biological tissue.
We present a theoretical and computational model for collagen turnover in soft biological tissues. Driven by alterations in the mechanical environment, collagen fiber bundles may undergo important chronic changes, characterized primarily by alterations in collagen synthesis and degradation rates. In particular, hypertension triggers an increase in tropocollagen synthesis and a decrease in colla...
