Regularized ultrasound phantom-free local Attenuation Coefficient Slope (ACS) imaging in homogeneous and heterogeneous tissues
Rafati, Iman; Destrempes, François; Yazdani, Ladan; Gesnik, Marc; Tang, An; Cloutier, Guy (Institute of electrical and electronics engineers, 2022-11-01)Attenuation map or measurements based on local attenuation coefficient slope (ACS) in quantitative ultrasound (QUS) has shown potential for diagnosis of liver steatosis. In liver cancers, tissue abnormalities and tumors detected using ACS are also ... -
The revisited frequency-shift method for shear wave attenuation computation and imaging
Yazdani, Ladan; Bhatt, Manish; Rafati, Iman; Tang, An; Cloutier, Guy (2022-04-11)Ultrasound (US) shear wave (SW) elastography has been widely studied and implemented on clinical systems to assess the elasticity of living organs. Imaging of SW attenuation reflecting viscous properties of tissues has received less attention. A revisited ...
