HBCol can automatically collect the results from HBCal.

 

肝脏血流灌注计算器

Hepatic Blood Supply Calculator, HBCal

 

肝脏血流灌注计算器可以帮助计算肝脏血流灌注指标，包括肝动脉系数，门静脉系数，动脉增强分数。使用者只需输入肝脏三期增强CT平扫期、动脉晚期、门静脉期、延迟期4期：肝脏任意部位（或肿瘤）、腹主动脉（腹腔干水平）、门静脉（左右支分叉附近）3个部位平均CT值（单位HU），点击计算即可得到结果。

 

HBCal can calculate hepatic blood supply parameters,including hepatic artery coefficient (HAC), portal vein coefficient (PVC), arterial enhancement fraction (AEF) of HCC or liver based on mean attenuation values (Hounsfield units) of regions of interest in the HCC or liver, aorta (at the level of the celiac artery), and portal vein (near the bifurcation) in different phases of triphasic CT.

肝脏血流灌注功能图绘制器

Hepatic Blood Supply Image Maker, HBIM

 

肝脏血流灌注功能图绘制器可以重建出肝动脉血供功能图、门静脉血供功能图、和动脉增强分数功能图。使用者在肝脏三期增强CT的DICOM数据平扫期、动脉晚期、门静脉期、延迟期4期，勾画肝脏轮廓，即可的得到上述图像。

 

HBIM can reconstruct HAC, PVC, and AEF functional images by delineate the liver in different phases in original DICOM data from triphasic CT.
