提出了一种基于衍射层析成像原理的超声成像技术。该方法利用发射机和探测器的固定圆形配置。之所以选择这种配置，是因为它避免了与医学成像设备设计相关的许多实际限制。实际考虑也促使纳入与发射机波束方向图有关的影响，而不是追求需要平面波照明的更传统的方法。此外，还考虑了密度和可压缩性变化分别成像的问题。
A technique for ultrasonic imaging based on the theory of diffraction tomography is presented. The method utilizes a fixed, circular configuration of transmitters and detectors. This configuration was selected because it avoids many practical limitations associated with the design of a medical imaging device. Practical considerations also motivated the inclusion of effects associated with the transmitter beam pattern rather than pursuing the more conventional approach in which plane-wave illumination is required. In addition, the problem of separately imaging both density and compressibility variations is considered.
