The Add Study dialogue box is then displayed where the Patient Type is selected to perform the study. Due to a software defect, when the study is initiated by pressing Start Procedure , the Patient Type changes inadvertently to a Patient Type different than the one selected as shown in the Table below. Patient type is one of the factors involved in the dose control process. The incorrect patient type changes the technique factors to be used by the system without notification to the user.
