Perfusion CT is a feasible technique for obtaining quantitative informations about tumor-related vascularization of liver. Time Attenuation Curve (TAC) computation is the first step to obtain perfusion parameters from mathematical modeling. We apply “slope method” analysis to TAC to assess arterial blood flow (BFa) in liver tumor (HCC-Hepatocellular Carcinoma). A new algorithm which removes outlier...
Radiofrequency (RF) ablation uses RF current to heat and kill cancer applied via an electrode inserted under image-guidance, and is in clinical use for tumors in liver, lung kidney, and bone. Mathematical models are frequently used to determine tissue temperature during RF ablation, but most prior models do not include accurate implementation of power control algorithms as are used in clinical devices...
Hyperthermia treatment incorporating magnetic nanoparticles (MNPs) is a hopeful therapy for cancers. Acquiring information about the MNPs' deposition in tumor tissues and modeling magnetic heating invivo are essential for successful treatment. In this paper, we discuss the inhomogeneous heat generation by MNPs distributed heterogeneously in a liver tumor during arterial embolization hyperthermia...
