common diagnostic procedure for visualizing cardiac function
in human subjects. Recently, this procedure has been modified
to evaluate cardiac function in mice. However, the high heart
rates encountered in these animals (often greater than 400
beatdmin) can confound R-wave trigger devices, acquisition
systems and image processing software containing default
conditions tailored specifically to the lower heart rates of
human subjects. In order to determine whether data acquisition
and processing components of a commercial or self-generated
gated blood pool imaging procedure are performing properly,
input of known timing and imaging signals that mimic those
generated during high heart rate gated blood pool imaging is
required. Here, we describe an inexpensive phantom that is
suitable for initial evaluation of an unknown system or for
ongoing QC of a previously verified system.[+][-]
