我们提出了一个霍特林观测器的实现，可以应用于数字乳房断层合成中线性图像重建算法的优化。该方法基于考虑特定感兴趣区域内的信息，并将其应用于微钙化可检测性算法的优化。考虑了几种线性算法：简单反投影、滤波反投影、反投影滤波和层析成像。然后通过重建幻像数据来评估优化后的算法。该方法在算法和参数上表现出鲁棒性，并导致生成的算法实现在主观上看起来针对感兴趣的任务进行了优化。
We propose an implementation of the Hotelling observer that can be applied to the optimization of linear image reconstruction algorithms in digital breast tomosynthesis. The method is based on considering information within a specific region of interest, and it is applied to the optimization of algorithms for detectability of microcalcifications. Several linear algorithms are considered: simple back-projection, filtered back-projection, back-projection filtration, and-tomography. The optimized algorithms are then evaluated through the reconstruction of phantom data. The method appears robust across algorithms and parameters and leads to the generation of algorithm implementations which subjectively appear optimized for the task of interest.
