In this work, a study of hepatocellular carcinoma and normal livers in rats using nuclear magnetic resonance (NMR) based on superconducting quantum interference devices (SQUIDs) was presented. The time domain free induction decay signals, Sy(t), of cancerous liver tissue and control liver tissue of rats were measured to study the respective longitudinal relaxation rate T1-1 . The NMR data were fitted...
Active Appearance Models (AAMs) is a deformable model based on statistical information, and also is an efficient method of image segmentation by extracting the features of the image. Its statistical analysis is Principal Component Analysis (PCA). PCA only takes into account the second order statistical information, which doesn't include the phase information, so it is difficult to extract the local...
High-temperature superconducting (HTS) coil is one of the best ways to increase the signal-to-noise ratio (SNR). Bi2Sr2Ca2Cu3Ox (Bi-2223) tapes were suitable to use because of the easier fabrications and lower cost. In this study, we built HTS Bi-2223 tape coils and demonstrated that the SNR of using the HTS tape coil was 3 or 4 folds higher than that of the traditional copper coil for a rat brain...
One way to reduce receiving coil noise in MRI scans is using non-resistive high-temperature superconducting (HTS) coils. They show advantages of much lower cost and easier fabrication over HTS thin film coils. In this work, we built a 200 mm in diameter Bi2Sr2Ca2Cu3Ox (Bi-2223) tape HTS RF coil and demonstrated that the SNR of using the HTS tape coil was 2.22 folds higher than that of the traditional...

High-temperature superconducting (HTS) coil is the reactance created by the inductive loop. A trimmer one of the best ways to increase the signal-to-noise ratio (SNR).
