Summary: | The invention discloses a photon counting non-vision-field three-dimensional imaging super-resolution method based on interpolation. The method comprises the following two steps of 1, selecting a proper interpolation method for low-resolution acquisition data, and completing data interpolation to obtain updated acquisition data, and 2, performing inversion reconstruction on the updated acquisition data according to a non-vision-field reconstruction algorithm to obtain a three-dimensional image with a higher resolution. The method can effectively solve the problem that a non-vision-field imaging system based on the photon counting technology needs a large amount of accumulation time when high-resolution and high-frame-rate imaging is carried out.
本发明公开了一种基于插值的光子计数非视域三维成像超分辨方法。该方法包括以下两个步骤:步骤一:对低分辨率的采集数据选择合适的插值方法,完成数据插值,得到更新的采集数据;步骤二:根据非视域重建算法对更新后的采集数据进行反演重建,得到更高分辨率的三维图像;该方法可以有效地解决基于光子计数技术的非视域成像系统在进行高分辨率、高帧率成像时需要大量累积时间的问题。 |
