FIGURE 1. (A) A simplified schematic presentation of the phantom. Under the kidney containers are 7 steel plates. Six of the 7 plates have been moved away from the space between the -camera detector and the left kidney container, and 2 of the 7 have been moved under the right kidney container. (B) A photograph of the phantom on a -camera, beside the control unit on a table.
FIGURE 2. (AD) The simulated 4 curves and corresponding regions of interest (white outlines drawn around the kidney areas). (E) An example of the image series of a simulation. Each image is summed over a period of 1 min 45 s. The series goes from left to right, starting at the upper left corner.
