摘要目的了解血液灌注分布对于活体成像实性肿瘤的异质性判断是非常重要的,它建立构成肿块多参数,包括缺氧、营养梯度、细胞活力、增殖和药物反应电位等。材料与方法我们开发了一种基于体积的方法,即多光谱光声层析 Abstract Objective To understand the heterogeneity of blood perfusion distribution in vivo imaging of solid tumors. It is important to establish multi-parameters of tumor mass, including hypoxia, nutrient gradient, cell viability, proliferation and drug response potentials. Materials and Methods We developed a volume-based approach, multispectral photoacoustic tomography
