Tuy和其他人已经导出了使用锥束几何进行完全采样的充分条件。这里,我们用平行光束准直的奥尔洛夫条件的语言和几何形式来表示图伊锥束条件。可以从该条件确定什么体积被完全采样。这种反演已经在软件中实现。软件确定任意轨道的完全采样体积的下限。
Tuy and others have derived a sufficiency condition for complete sampling using a cone-beam geometry. Herein, we express Tuy's cone-beam condition in the language and geometry of Orlov's condition for parallel-beam collimation. One may determine from this condition what volume is completely sampled. This inversion has been implemented in software. The software determines a lower bound on the completely sampled volume for arbitrary orbits.
