The authors proposed a new usage of an imaging plate (IP) technique for estimating this uncertainty. This method needs only to set an array of regions of interest (ROIs) on a latent image obtained from the IP; each of the ROIs corresponds to an active area of the detector to be used. This work benchmarked the method through an experiment using a realistic torso phantom containing an 241Am liver source. The latent image of the source was obtained by irradiating the IP (20 x 40 cm2) from the anterior surface of the phantom. The phantom was also measured with a HPGe detector with an active area of 70 mm in diameter. As a result, the comparison in the response between the IP and the HPGe detector was made for six of 144 circular ROIs arranged on the latent image, showing in a good correlation (r2= 0.994). This suggested that the uncertainty of concern in the present measurement with the HPGe detector was inherited from the dispersion of counts on the latent image: 8.2% of the 144 ROIs. Although a practical use of the IP in the direct organ measurements still has difficulties (e.g., a fading effect), the IP would be a useful tool not only for optimizing the detector location, but also for avoiding possible underestimations of the activity amount due to inappropriate locations of the detector by visual confirmation.
