Images?of?the?human?body?are?derived?from?the?interaction?of?energy?with?human?tissue.?The?energy?can?be?in?the?form?of?radiation,?magnetic?or?electric?fields,?or?acoustic?energy.?The?energy?usually?interacts?at?the?molecular?or?atomic?levels,?so?a?clear?understanding?of?the?structure?of?the?atom?is?necessary.?In?addition?to?understanding?the?physics?of?the?atom,?learning?imaging?jargon?is?also?necessary.?For?example人体的图像来自能源与人类之间的相互作用的组织。能量可以以辐射的形式,磁场或电场,或声波能量,能量通常在分子或原子水平相互作用,所以清楚地了解原子的结构是必要的。除了了解原子的物理,学习成像术语也是必要的。例如: ??Tomography:?a?cross-sectional?image?formed?from?a?set?of?projection?images.?The?Greek?word?tomo?means?cut.? ?断层扫描:横断面图像由一组投影图像。希腊语tomo意味着削减。 ??CT:?Computed?(or?Computerized)?Tomography? ?CT:(或计算机)计算层析成象技术 ??MR,?or?MRI:?Magnetic?Resonance?Imaging.?This?was?first?called?nuclear?magnetic?resonance?(NMR),?but?the?mention?of?anything?nuclear?scared?patients,?so?the?“N”?was?dropped.? ?先生,或MRI:磁共振成像,这是第一次被称为核磁共振(NMR),但提到任何核害怕病人,所以“N”掉了。 ??PET[1]:?Positron?Emission?Tomography.?Understanding?this?phenomenon?requires?acceptance?of?the?theory?that?there?is?antimatter?in?the?universe,?and?when?antimatter?meets?matter,?then?both?kinds?of?matter?are?annihilated,?and?pure?energy?is?formed.? ?宠物[1]:正电子发射断层扫描,理解这种现象需要接受的理论,宇宙中有反物质,反物质与物质,这两种物质是湮灭,纯粹的能量就形成了。 ??SPECT[2]:?Single?Photon?Emission?Tomography???Ultrasound:?Sonar?in?the?body? ?SPECT[2]:单光子发射断层扫描?超声波:声纳 ??OCT:?Optical?Coherent?Tomography?–?the?use?of?infrared?light?to?image?(particularity)?the?walls?of?an?art?10月:光学相干断层扫描,使用红外线图像(特殊性)动脉的城墙A?modality?is?a?method?for?acquiring?an?image.?MR,?CT,?etc.?are?all?imaging?modalities.?Modalities?are?sometimes?categorized?based?on?the?amount?of?energy?applied?to?the?body.?For?example,?the?X-ray?modality?produces?energy?that?is?sufficient?to?ionize?atoms?(i.e.,?eject?an?electron?from?an?orbit?of?an?atom,?thereby?creating?a?positively?charged?ion?that?damages?human?tissue).?The?modalities?that?cause?ionizing?radiation?are?X-rays,?CT,?SPECT,?and?PET.?Non-ionizing?modalit
