摘要: A first generating unit generates a plurality of blood vessel image data sets at the plurality of imaging angles by performing subtraction processing for the plurality of mask image data sets and the plurality of contrast image data sets. A second generating unit generates a blood vessel volume data set including an artery region, a vein region, and a capillary vessel region by performing reconstruction processing for the plurality of blood vessel image data sets. A third generating unit generates a capillary vessel volume data set associated with the capillary vessel region by removing the artery region and the vein region from the blood vessel volume data set. A fourth generating unit generates a capillary vessel image data set by performing three-dimensional image processing for the capillary vessel volume data set.
摘要翻译: 第一生成单元通过对多个掩模图像数据组和多个对比度图像数据组进行减法处理,在多个成像角度生成多个血管图像数据组。 第二生成单元通过对多个血管图像数据组进行重建处理,生成包括动脉区域,静脉区域和毛细血管区域的血管容量数据组。 第三生成单元通过从血管容积数据集中移除动脉区域和静脉区域而产生与毛细血管区域相关联的毛细血管容积体数据集。 第四生成单元通过对毛细血管容积数据组进行三维图像处理来生成毛细管血管图像数据。
