Calculation of Renal Depth by Conjugate-View Method Using Dual-Head Gamma Camera
In this study, we developed a new method for the determination of renal depth with anterior and posterior renal scintigrams in a dual-head gamma camera, considering the attenuation factor e[superscript -μx] of the conjugate-view method. We developed abdomen and kidney phantoms to perform experiments using Technetium-99m dimercaptosuccinic acid (99mTc-DMSA). The phantom images were obtained by dual-head gamma camera equipped with low-energy, high-resolution, parallel-hole collimators (ICONf, Siemens). The equation was derived from the linear integration of emission γ-ray considering attenuation from the posterior abdomen to the anterior abdomen phantom surface. The program for measurement was developed by Microsoft Visual C++ 6.0. Renal depths of the phantoms were derived from the derived equations and compared with the exact geometrical values. Differences between the measured and the calculated values were the range of 0.1 to 0.7 cm (0.029± 0.15 cm, mean ±S. D.). The present study showed that the use of the derived equations for renal depth measurement, combined with quantitative planar imaging using duel-head gamma camera, could provide more accurate results for individual variation than the conventional method
