Abstract
We propose two continuous shear wave elastography visualization methods to reveal hardened tissue areas regardless vibration direction. Using a tissue-mimicking phantom, vibrations at 78.1 Hz were applied from both the longitudinal and transverse directions relative to the probe. Small-divided-region shear wave velocity imaging consistently identified stiff inclusions under both conditions, while shear strain imaging clearly highlighted their boundaries. Conventional shear wave velocity imaging, in contrast, showed direction-dependent variability.
