7.字段视野(Field of View,FOV): - FOV是指在图像中包含多大范围的解剖结构。FOV的大小与图像的空间分辨率有关。 8.空间分辨率(Spatial Resolution): -衡量图像中细节的清晰度和显示能力。空间分辨率取决于矩阵大小、切片厚度和FOV。 9.融合图像(Contrast Weighting): - MRI可以生成不同对比度的图像,根据所选择的...

Purpose: In diffusion MRI (dMRI), the volumetric and bundle analyses of whole-brain tissue microstructure and connectivity can be severely impeded by an incomplete field-of-view (FOV). This work aims to develop a method for imputing the missing slices directly from existing dMRI scans with an...
4. 视野 视野(fieldof view,FOV)是指MR成像的实际范围,即图像区域在频率编码方向和相位编码方向的实际尺寸,如30 cm×30 cm,因而是个面积概念。在矩阵不变的情况下,FOV越大,成像体素越大,图像层面内的空间分辨力降低。 5. 矩形FOV 一般的FOV是正方形的,但有些解剖部位各方向径线是不同的,如腹部横断面的前后...
Parameters for small- field-of-view imaging were as follows: field of view, 10.0 × 10.0 cm; matrix, 256 × 512 (dis- played at 512 × 512); slice thickness, 3 mm with a 0.3-mm interslice gap; and number of averages, 3. Imaging planes and sequences for the examination with the...
