Large-Scale Propagation of Ultrasound in a 3-D Breast Model Based on High-Resolution MRI Data
2010
IEEE Transactions on Biomedical Engineering
A 40 × 35 × 25-mm 3 specimen of human breast consisting mostly of fat and connective tissue was imaged using a 3-T magnetic resonance scanner. The resolutions in the image plane and in the orthogonal direction were 130 μm and 150 μm, respectively. Initial processing to prepare the data for segmentation consisted of contrast inversion, interpolation, and noise reduction. Noise reduction used a multilevel bidirectional median filter to preserve edges. The volume of data was segmented into regions
