Hoffman 3-D腦模體，霍夫曼腦模體工作原理：

-在腦部SPECT及腦部PET的研究中，從解刨學(xué)角度精確的模擬放射性分布；在MRI研究中，精確模擬質(zhì)子密度及馳豫參數(shù)打的分布
Anatomically accurate simulation of radioactivity distribution for brain SPECT and brain PET studies* and distribution of proton density and relaxation parameters for brain MRI studies
-在血流和代謝研究中模擬正?；屹|(zhì)和白質(zhì)的4:1攝取率(按部分體積效應(yīng)模擬)
Simulates 4:1 uptake ratio (by partial volume effect) seen for normal gray and white matter in flow and metabolic studies
-單體填充腔設(shè)計，消除了制備不同濃度放射性物質(zhì)的必要
Single fillable chamber eliminates the necessity of preparing different concentrations of radioactivity
-為基底神經(jīng)節(jié)區(qū)域提供了可填充固體缺陷
Fillable and solid defects for basil ganglia region available
