该方法涉及一种从至少一个接收元素的投影数据生成图像的系统，包括输入投影数据，生成包含位置和信号数据的第一数据点阵列，随机移除数据点形成多个子阵列，基于子阵列生成初步图像，比较像素确定每个位置的较小或等于像素值，合并这些值以形成最终图像，重复此过程直至达到所需图像质量。
摘要：
A method and system for generating images from projection data; a preferred embodiment comprising inputting projection data from at least one receiving element; generating a first aperture or array of data points containing positional and signal data; arbitrarily and/or randomly removing data points from the first array to form a series of subarrays comprising different sets of data points; generating preliminary images from the subarrays; comparing the corresponding image pixels from two preliminary images to determine for each pixel location the lesser or equal pixel values; forming a merged image from the lesser or equal pixel values; and repeating the comparison of corresponding image pixels of another preliminary image to the merged image to determine the lesser or equal pixel values until a merged image of the desired quality is obtained. A preferred embodiment of the system may comprise at least one processor, comparator and/or image generator.
