在医学诊断术中关于三维物体特定断层面的成象问题或多或少已被X射线断层面照相法和断层面综合法所解决。但由于这些方法纪录过程相继的时间——纪录时间范围在几秒钟——所以不可能评价运动着的三维物体诸如跳动着的心脏图象。为了克 In medical diagnosis, the imaging problem of a particular slice of a three-dimensional object has been more or less solved by X-ray tomography and tomosynthesis. However, due to the sequential recording of these methods, which take several seconds to record, it is not possible to evaluate moving three-dimensional objects such as beating heart images.
