IMPROVEMENTS IN OR RELATING TO ULTRASONOGRAPHY

摘要

Local aberrations in the perfusion and/or compliance of vasculated tissue may be detected by contrast agent-enhanced ultrasound imaging procedures wherein a sequence of ultrasound image data is generated in respect of a region of interest in vasculated tissue, the image data is processed to generate waveforms representative of arterial pulsatility, and these waveforms are analysed for variations such as phase distortions which are characteristic of local aberrations in tissue perfusion and/or compliance.
