A comparison of one shot and continuous modes for Shear Wave

When using the shear wave elastography mode, the Aplio 500 system supplies two methods to obtain readings of meters per second (m/s), and kilopascals (kPa) to assess the stiffness of tissues in the human body; the one-shot and continuous methods. The one-shot method activates the main pulse over one frame to measure the resultant speed of the shear wave and elasticity in the tissue being examined. A single image is produced to register the stiffness measurements. The continuous mode provides a live acquisition of the elastographic and propagation maps, and multiple images are acquired over time. It is also possible to cine-loop back through the frames to register multiple stiffness measurements from the one acquisition. Read the full paper now…
