美国DSC Hoffman 多隔室2-D脑模体™主要特点:-解刨学上矫正不同的同位素摄取率；模拟正常及异常人体脑部的血流及代谢影像中的活动分布Anatomically correct – varying isotope uptake ratios – simulation of the activity distribution in a flow or metabolic image of normal and abnormal human brain*-七(7)个灰质隔室，可分别填充不同数量的放射性示踪剂，以模拟一系列不同的“热”和“冷”异常Seven (7) gray-matter compartments that may be separately filled with varying amounts of radiotracer to simulate a variety, of “hot” and “cold” abnormalities-正常灰质:白质:脑室放射性活度比为4:1:0 (按部分体积效应模拟)Normal gray-matter:white-matter:ventricle activity, ratio is 4:1:0 (simulated by partial volume effect)-异常灰质:正常灰质活动比率可在0.25:1到大于100:1范围内调整Abnormal-gray-matter:normal-gray-matter activity, ratios can be varied from 0.25:1 to greater than 100:1美国DSC Hoffman 多隔室2-D脑模体™主要应用领域:-用于针对SPECT及PET系统的研究、系统性能测定、优化成像协议、影像诠释及培训 SPECT and PET applications include research, system performance measurements, optimization of imaging protocols, image interpretation, and training图A：Hoffman 多隔室2-D脑模体™的SPECT影像及轮廓，箭头指示的隔室显示加剧的放射性活动，以模拟发作期时灌注量增加67%的现象SPECT image and profile of Hoffman 2-D Multi-Compartment Brain Phantom™ with a compartment (arrow) filled with increased activity to simulate a 67% increase in perfusion during an intraictal phase图B：Hoffman 多隔室2-D脑模体™的SPECT影像及轮廓，箭头指示的隔室显示衰减的放射性活动，以模拟发作期时灌注量减少67%的现象SPECT image and profile of Hoffman 2-D Multi-Compartment Brain Phantom™ with a compartment (arrow) filled with decreased activity to simulate a 67% reduction in perfusion during an interictal phase.图C：Hoffman 多隔室2-D脑模体™的SPECT影像及轮廓，箭头指示的隔室显示衰减的放射性活动，以模拟发作期时灌注量减少33%的现象SPECT image and profile of Hoffman 2-D Multi-Compartment Brain Phantom™ with a compartment (arrows) filled with decreased activity to simulate a 33% reduction in perfusion in the left frontal lobe.* Hoffman EJ, Ricci AR, van der Stee LMAM, Phelps ME.
