B-Flow の技術とその臨床結果

概要

論文の詳細を見る
Blood flow can be visualized at a higher resolution and higher frame rate with the new technique, B-Flow, than with CFM or PDI. Small signals were detected by digitally encoded ultrasound (DEU) using LOGIQ 700 EXPERT Series. DEU is the original GE technique. LOGIQ 700 can transmit the encoded pulses and decode them on receipt in order to improve SNR or to suppress unwanted signals. DEU improves major imaging methods such as B-mode and harmonic imaging, in terms of resolution, penetration and frame rate.<BR>The key aspects of B-Flow are Coded Excitation and tissue equalization. Coded Excitation can detect much weaker signals from blood cells. Tissue equalization can reduce non-moving tissue signals to the level of the flow signals; both signals may be displayed simultaneously without overlay (as in color-flow) .
