Heterogeneous tissue characterization using ultrasound: a comparison of fractal analysis backscatter models on liver tumors

no code implementations20 Dec 2019 Omar S. Al-Kadi, Daniel Y. F. Chung, Constantin C. Coussios, J. Alison Noble

Performance was assessed based on 608 cross-sectional clinical ultrasound RF images of liver tumors (230 and 378 demonstrating respondent and non-respondent cases, respectively).

Quantification of Ultrasonic Texture heterogeneity via Volumetric Stochastic Modeling for Tissue Characterization

no code implementations14 Jan 2016 O. S. Al-Kadi, Daniel Y. F. Chung, Robert C. Carlisle, Constantin C. Coussios, J. Alison Noble

In the case of ultrasound, the Nakagami distribution is a general model of the ultrasonic backscattering envelope under various scattering conditions and densities where it can be employed for characterizing image texture, but the subtle intra-heterogeneities within a given mass are difficult to capture via this model as it works at a single spatial scale.
