Advantages and Precision of Technique. As a result of low-angle filtration, the intensity at the exit of the capillary
structure is significantly less than the total flux emanating from the surface of the anode. In certain cases, this is useful
since it is then no longer necessary to install additional x-radiation attenuators for the purpose of preventing overloading of
the detector systems.
The precision of the technique and the minimal threshold of the dimensions of the spots are limited by the dimension
of the element of the transmitted image, or effective dimension of the channel, i.e., the resolution of the given optics
(cf. Fig. 1).
