Figure 3.

These figures show the following parameters, determined via the algorithm in Sec. 3B, as a function of object size: (a) pinhole diameter, (b) fraction of detector filled, (c) object-to-pinhole distance, (d) pinhole-to-detector distance, (e) total system length, (f) magnification, (g) resolution in object space of a projection image (overall system resolution is shown as well as the three individual components), and (h) sensitivity (counts∕s/mCi). These results are for the imaging system diagrammed in Fig. 2, where the single pinhole has four diameter choices (0.25, 0.5, 1.0, 1.25 mm) and the system has a maximum length of 283 mm.
