由于与这些放射性核素的衰变相关的低能 X 射线和光子的严重衰减，全身计数数据的最佳使用来估计许多锕系元素的肺部沉积取决于胸壁厚度的精确测量。基于测量的胸壁厚度与其他常见生物特征量的相关性，导出了一种通过实时超声测量验证的女性胸壁厚度估计算法。使用该算法将减少通常与先前由于假设所有女性受试者的平均胸壁厚度而产生的内部锕系元素沉积估计相关的误差。
Optimal use of whole-body counting data to estimate pulmonary deposition of many of the actinides is dependent upon accurate measurement of the thickness of the chest wall because of severe attenuation of low-energy x rays and photons associated with the decay of these radionuclides. An algorithm for estimation of female chest wall thicknesses, verified by real-time ultrasonic measurements, has been derived based on the correlation of measured chest wall thickness and other common biometric quantities. Use of this algorithm will reduce the error generally associated with estimation of internal actinide deposition previously resulting from assuming an average chest wall thickness for all female subjects.
