报告内容：

Among recently appeared medical imaging techniques, diffusion tensor magnetic resonance imaging (DTI) has received particularly intensive attention of researchers and clinical doctors. DTI has emerged as a new and promising technique for investigating the 3D fiber structures of brain and heart tissues. A weak point of DTI is however its relatively low signal-to-noise ratio (SNR) due to the difficult dilemma between acquisition time and image quality. This presentation attempts to present a recent method for denoising diffusion weighted images in DTI. Different aspects, from mathematical formulation to final adaptive filtering, will be dealt with.
