In the case of ultrasound colour flow imaging (CFI) (known also as colour Doppler imaging), a colour map depicting movement is superimposed on the PE image (figure 2). Because ultrasound images are captured in real-time, they can show the structure and movement of the body’s. Only the mode that is active during the US examination can undergo optimization. This physical phenomenon is related to change in wave frequency that is observed when the wave is moving or when it is reflected off a moving object. STIC, tissue Doppler, and multiplanar imaging are added advantages. Ultrasound Probes Transducer. It appears attached to the upper wall of the gall bladder, though some movement was present on real time imaging. Check best price of Portable Color Doppler Ultrasound. With this technique it became possible to directly "observe" blood flow within the heart. Recently, color-doppler ultrasound, spleen and liver stiffness measurements via point shear wave elastography have shown promise in potentially serving as non-invasive methods to assess for dysfunction[12-16].
