A mathematical model to determine facility needs for a radiology department.

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).
