Radiography. 1978 May;44(521):116-28.
In summary, a mathematical model has been developed, tested, and applied which measures effectively the number as well as the type of radiographic rooms needed to meet the current and projected radiographic demand for a typical health care facility. The model first required a projection of radiographic procedures, based on historical data. Secondly, the projected total by patient classification was subdivided into procedure categories. Finally, the projected categorised radiographic procedures are introduced into the formula (Equation 1) and is shown below: (formula: see text). The formula is applied to each procedure category. The grand total for each of the four separately calculated categories will measure the total number of rooms and type of facility needed in the future. (formula: see text).
综上所述，已开发、测试并应用了一种数学模型，该模型能有效测算出满足典型医疗机构当前和预计的放射检查需求所需的放射科室数量及类型。该模型首先需要根据历史数据对放射检查程序进行预测。其次，按患者分类的预测总数被细分为程序类别。最后，将预测的分类放射检查程序代入公式（公式1），如下所示：（公式：见正文）。该公式应用于每个程序类别。分别计算的四个类别中每一个的总计将测算出未来所需的房间总数和设施类型。（公式：见正文）
