1.1多模生物医学三维(3D)生物医学成像始于1960年S-1970年S(Cormack，1963，Hounsfield，1973)的计算机断层扫描(CT)，随后是1970年S(Lauterbur，1973，Garroway等，1974，Mansfield&Maudsley，1977)的磁共振成像。这些解剖成像技术是基于患者解剖的物理特征，如线性衰减系数或电磁相互作用和松弛。三维生物成像(分子成像或功能成像)，如正电子发射断层扫描和单光子发射计算机断层扫描，也是在20世纪70年代中期发展起来的(S，Ter-Pogossian等，1975，菲尔普斯等，1975)。他们使用标记有正电子发射器或伽马发射器的分子探测器来检测生物特征，以瞄准分子、细胞或生理事件、过程或产品。因此，来自特定解剖部位的x射线/γ射线强度与放射性标记分子标记的浓度直接相关。因此，生物事件将在3D空间中成像。自从混合PET/CT扫描仪的概念被引入(Beyer，et al，2000)以来，生物图像和解剖图像的联合配准提供了空间中的生物和解剖学信息，假设在两个图像采集之间和期间没有患者的运动。还开发了其他组合扫描仪，如SPECT/CT和PET/MRI(Cho等人，2007年，Bybel等人，2008年，Chowdhury&Scarsbrook，2008年)。生物和解剖图像在采集或采集后的配准提供了关于患者疾病阶段的多维信息(Ling，et al，2000)，便于用于诊断的病变识别和用于治疗的靶点勾画。
1.1 Biomedical Imaging of Multimodality Three-dimensional (3D) biomedical imaging starts from computed tomography (CT) in 1960’s-1970’s (Cormack, 1963, Hounsfield, 1973) followed by magnetic resonance imaging (MRI) in 1970’s (Lauterbur, 1973, Garroway et al, 1974, Mansfield & Maudsley, 1977). These anatomical imaging techniques are based on physical features of a patient’s anatomy, such as linear attenuation coefficient or electromagnetic interaction and relaxation. 3D biological imaging (molecular imaging or functional imaging), such as positron emission tomography (PET) and single photon emission computed tomography (SPECT), was also developed in mid 1970’s (Ter-Pogossian, et al, 1975, Phelps, et al, 1975). They detect biological features using a molecular probe, labelled with either a positron emitter or a gamma emitter, to target a molecular, cellular or physiological event, process or product. So, the x-ray/γ-ray intensity from a particular anatomical site is directly related to the concentration of the radio-labelled molecular marker. Therefore, a biological event will be imaged in 3D space. Since the concept of hybrid PET/CT scanner was introduced (Beyer, et al, 2000), the coregistration of biological image with anatomical image offers both biological and anatomical information in space, assuming that there is no patient’s motion between and during the two image acquisitions. Other combined scanners, such as SPECT/CT and PET/MRI, have also been developed (Cho, et al, 2007, Bybel, et al, 2008, Chowdhury & Scarsbrook, 2008). Registration of biological and anatomical images at acquisition or post acquisition provides multi-dimensional information on patient’s disease stage (Ling, et al, 2000), facilitating lesion identification for diagnosis and target delineation for treatment.
