Which segment leads?
Ultrasound-based and Doppler technologies represent an important portion of the blood-flow measurement landscape, owing to their established use in clinical imaging and flow assessment. Doppler ultrasound measures blood-flow velocity by analyzing frequency shifts associated with moving blood cells and has evolved into continuous-wave, pulsed-wave, color Doppler, power Doppler, and other advanced imaging approaches.
Laser Doppler technology is another important segment, particularly for assessing microvascular and tissue perfusion. Laser Doppler flowmetry uses optical signals generated by moving blood cells to derive information about tissue perfusion. Laser Doppler imaging can also provide perfusion maps across larger tissue areas.
Transit-time flow measurement is particularly relevant to intraoperative cardiovascular and vascular applications. Unlike Doppler measurements that primarily provide velocity information, TTFM can quantify blood-volume flow in vessels and grafts. This makes it useful for assessing blood flow during surgical procedures.
